As a landscaper of a few years now, I'd like to point out that it might be way easier to have one large motor spin two blades instead of all the smaller blades. This will disperse the grass farther out and will have a much higher speed at the cutting edge, meaning that it would cut more effectively even when dull. It would probably save battery power too. Hope you read this.
i was thinking something more like those old rotary movers Way back int he day. or maybe a hedge trimmer style with high torque, and a chain rake to move grass to one side. or, mimics a combine harvester mechanism
He is also using this in super long grass, which even for commercial mowers can present a challenge at times, especially when wet. It's pretty impressive it somewhat worked, I was expecting him to use it on like 3 inch grass
As a farmer I can inform you that cutting thick brush in your case with such small scale you don’t use speed you use momentum with a heavy blade but if you mow your yard regularly your little rig will work good and if you look a a lawn mower the blades are angled to throw the grass away
Super cool! I have 2 questions: Do you have the 2 blades on the left running counter-clockwise and the 2 blades on the right running clockwise? This would help clear the cut grass out of the way better. Do you have plans for an autonomous mower??? That would be super cool!
Autonomous lawn mowers have been a thing for at least a decade. If it was just him, then they might pass a law but there's a built up industry, and therefore, a lobby to prevent any regulation on them.
@@crazycarl864 Lobbies promote regulation to make sure they're the only players in town. The government will pass laws precisely to stop the "just hims" to make sure the corporations can make bank. Did you know that the 1968 gun control act was envisioned by Thomas J. Dodd, a Connecticut politician with ties to the Connecticut gun industry? Connecticut was home of Colt, Winchester, Savage, Stag Arms, Mossberg & Sons, Sturm Ruger, etc. and the gun industry was suffering from the competition of war-bringbacks and surplus. Millions of rifles already bought and paid for during wartime that were sold to importers for pennies on the dollar were much cheaper to sporterize than buy factory new. That's just an example that's fresh on my mind because I learned it in a podcast the other day, the point is that corporations write laws that they know they can follow but stifle competition.
With the current shroud making the right two and left two blades spin away from the center and opening the ends would probably give the best performance. But it is going to be hard to discharge wet grass like that with such a small machine.
This is a super cool idea. It'd be good for disabled people who can't use a push mower or transfer easy into a riding mower. Heck, I'm in a power wheelchair and I'd totally use something like this to help elderly or other disabled people by mowing their lawns people's yards. You can have fun using an RC car AND be productive! I know they make grass cutting but those are at least $1000 and for small yards, it might be more beneficial to have a human that can navigate weird obstacles anyhow. You're channel is both entertaining but also very eye opening to what's possible
The concept is sound. But take it from someone who has been in lawncare for 30+ years. This would be great for a maintained lawn but you're trying to use it as a brushcutter. A few design changes I would make are as follows: - Pitch the trailing edge of the blades to about 15 degrees. This will provide airflow to help lift un-cut blades of grass, and to blow away the cut ones. -Take a look at most lawn tractor mower-decks which use multi-blade setups. The front of the deck is flat, while the rear is curved to hug the blades. Additionally, notice how the front of the deck increases in height toward the discharge chute. as the first blade cuts grass in its path, it will throw the grass toward the discharge chute and over the second blade down the line. The second blade also cutting ad discharging grass over the third, and so on. with each pass toward the chute, more clippings are being transported, thus needing more room to transport them. Hence the raise in the top-front edge leading to the chute. The top-rear of the deck can remain flat. Basically, build a mower-deck using the design from a typical lawn tractor deck, while adapting it to use your 4-blade configuration. Side note, The swing-away blades are a nice touch though. You'll see those on brush-hogs to allow the blade to deflect off of a hard object rather than breaking or bending due to being rigid. Another idea, one that I have wanted to try for a while is a rear-discharge deck. That rise toward the cute would begin on each outer side of the front of the deck and peak in the middle.then carry rearward to a rear-facing opening. however, the leading area two sets of blades would each need to rotate toward the center so the clippings can all be transported toward the chute, and thrown rearward. However it would be good to add a wedge at the front to the deck, between the the two centermost sets of blades to prevent the right side from trying to throw it's clipping into the left side & vice-versa. Helps to think of mower decks as centrifugal fans. think of airflow or fluid dynamics, and where you want it to go. Hope all that made sense.
you should make an autonomous rover that charges a lipo with its solar panels to activate the cutters once a week, with that you should be able to make some cool sattelite art in your field after a few months
Greetings from Finland! I think it would make a ton of difference if the blades weren't heading straight into the direction of movement, but to position them in a V-configuration like an old-fashioned snow plow. Then also implementing clockwise and counter-clockwise movement to reduce the amount of built up grass. Really cool project!
For cutting large swaths of grass and longer lengths. The Husqvarna robotic lawn mower uses razor blades and works on a higher frequency of cutting, but shorter cuts are required.
I think lawn mowers are optimized for humans, so they are about the size a human can push while still being big so it's faster work. For something that's autonomous, the time won't matter as much so it can be smaller. Weed whackers work just fine and are smaller. I think the largest issue here was that there was nowhere for the cuttings to go - it needs to push them to the side or something.
I'm not able to mow my lawn due to a stroke and ever since I wanted to build a robot lawn mower. Hence the reason I'm trying to learn how via DIY videos. I'm glad I came across your video. I'm going to order the Hobbywing QuicRun Fusion Brushless System Motor & ESC 2-in-1 1200Kv / 1800Kv 540 Waterproof For RC Crawler you suggested. I was quite impressed on how well your mower performed. Thanks for the video.
This is an awesome project! One thing to keep in mind- if this were to go on tour autonomous vehicle and run every day, it wouldn’t be mowing down tall grass. The grass would only grow so little, those little blades would be great! Take for example all the autonomous lawn mowers coming to market. Their blades are super tiny, but that okay because they’re only cutting a few millimeters of grass a day.
I was expecting a mower deck with some rc parts attached, but what i watched was even better. Like watching a dumpster fire going down hill into a daycare.
you need to add a auger on top of the blades in front and one behind the blades in the shroud. look at hay mowers for examples. the augers clear all the buildups
The amount of rainfall that you seem to get where you live has seriously impacted the end product of your videos. I know it's not something that you can easily change, just saying so you know what I found negative about your video. Great work all around. Very inspiring stuff.
Since discovering FPV I've ALWAYS wanted to build something like this so I could sit in a comfortable chair in my backyard and mow both my front and backyard and still have a bit of fun. This is the closest I've seen. I always envisioned using a self propelled mower stripped down, a couple of big servos for steering and actuating the propulsion mechanism and a big lithium ion battery.
Awesome project! Development seems to never end with this since the ideas keep coming up for improvements. Been working out the bugs on a moss pellet sprayer quad to keep me from crawling on the roof, seems the Washington rain really benefits or the pellet granules roll off the roof after the last couple test hops.

I really admire your determination to find a process that works when you run into a problem,plus the innovative ideas you come up with are inspiring! I like this build and may use some of your building ideas to make use of a working practical RC lawnmower that is variably simple yet reliable to handle some tough tasks in the yard mowing a tough lawn or weeds. Thank you definitely for sharing and agree there should be more interested people that can build these and modify results to make them better and share with others ideas for improvement!
One thing that holds this back is the blade geometry. Normal lawnmower blades have a angled part at the rear of the blade which causes the chopped grass pieces to fly up into the mower deck where they are bounced around until they make their way to the outsides of the mower and ejected. With completely flat blades, the mowed grass chunks fall back into the mower blades where they are rechopped and gum up the mower
This is the worst video I've ever seen on this channel. He tried to reinvent the lawnmower instead of simply adding RC to a regular lawn mower (which would have been easier, cheaper, and far more effective).
While visiting Sweden in 1995, I went on a tour of the Ringhals nuclear energy facility just north of Varberg. As fascinating as the nuclear plant was, I was amazed by the autonomous lawnmower that was mowing the grass around the plant. It was manufactured by Huskvarna.
@@TH-camAdministrator how can it be shitty if it’s cutting grass before it gets too long to be too much for the mower? And do you own one? The reviews I’ve read are pretty good on certain brands also they’re not that expensive if you’re about to spend the equivalent on a lawn mower.
They have autonomous mowers and commercially available units you mount to a full size commercial zero turn that are used for big fields. There are rc controlled units used for ditches and steep inclines as well
This video reminds me of Uncle Shortfinger. I met him a couple of times, but I never learned what his real name was. He was our introduction to lawnmower safety. I thought of him during the scenes with bare fingers cleaning up around the blades.
As someone who owns a Lawncare company, a couple tips for you would be 1: have some sort of way to move the blade heads higher or lower from the ground. 2. Put a movable metal rectangle on the top right above the blades, anything grass taller than the wire rectangle on top of the blades, I wouldn't use it for. 3. The grass is way too tall for this to function properly, I would say the best use for this would be to use after you initially mow your yard, so it's not trying to cut huge things of grass, it only keeps it trimmed and tighty after my luge already mowed. The best application would be to keep this thing running after you've used a real mower to take down the huge tall chunks of grass, and keep this thing running after you've mowed to keep it trimmed nicely and consistently.
This is so cool. Just did a school project where I designed a similar trimmer line testing rig. Designed to cut 24" tall wheat. Would love to show you how similar it is and how I aimed to avoid some of the issues you had. Keep in mind this is a huge rig that uses 14" strips of trimmer line. Lmk if you'd like to see it
Very cool project. I live really close to you so I know that the winter grass around here can be a serious challenge to cut. So I am super impressed at how well the mower did at the flying field.
More rotating mass on the cutters might help. And designing the cutters to have a lot of vertical airflow to help "pull" the grass upward might also help. Might be worthwhile experimenting with a cylindrical blade. Similar to older manual push mowers.
I can see u building a rc mower that has waypoints and mows the whole yard,, tc roomba mower, u would sell alot,, keep up the great content, love ur channel, from a 62 yo closet nerd 👍❤
Awesome job man!! 👍👍 All you need now is a camera mounted on a pole up above that you can access wirelessly and you can sit inside and mow your grass..... Food for thought!! 🤔
Spinning blades that can easily be touched while they spin. Yeah. That's horrifying. I wonder if a weed eater style cutter would work better. as I feel the lawn mower blades have mass and torque on their side.
@@georgewashington1621 believe me there is. I've had the fun of grabbing into a full speed 5inch prop that was only on 2s in a wing launch scenario. Those poly carbonate props go through skin like butter
@@georgewashington1621 No, it wasn't anything crazy like that. I want to say it had 3S motors but it was a while ago. I was writing a flight control firmware for it and I made a mistake in the code that made all the motors spin up to 100% and, like an idiot, I tried to grab it to disconnect the battery. Still have the scar to remember it by.
thats sad. when i was a kid i cut the front of a lawnmower off so the blades were exposed so i could cut down taller grass. also cut a hole in the top so i could feed in sticks to chop them like a woodchipper still have all 11 fingers
Couple things i noticed, (long time landscaper) I would suggest taking a look at commercial lawn mower decks. Look at the grass "pathway" tothe exit shoot on the right. They purposely have it all going to the same exit point and use the front edge of the deck as a channel. The smoother the spot that the grass travels at, the better it will expel. Also would suggest angling the deck upward in the front. Sounds odd, but I think if you had say 15% angle(?) on it it would help. So you would essentially set the rear at the desired cut height. This allows the front side to start cutting at a slight higher cut height and finish lower in the back. May help, and really just a thought. One really big thing i can say is, even with a $25k commercial mower, they dont easily go through grass above 5-6" let alone if wet. Starting at like a 4" cut height would help a lot. Also what if instead of exacto blades, try it more like a weed wacker?
This! Make em barbed (like arrow heads) to help direct and control the tall stalks. A RC lawnmower that cuts a lawn regularly as it starts to grow in shouldn't have issues with regular trimming. Its that "I'm too lazy to cut my lawn so its massive now." kind of cutting that will have issues.
The problem with this idea is that while corn is planted in fairly symmetrical rows, and thus grows as such, grass doesn't grow in any semblance of order. The fingers on a corn header just help to direct the corn onto the cutters and keep it from folding away; meanwhile, on a self-propelled mower, there's a big wheel like on a wheat head.
@@cbpercy06 sounds like you have some farming background and your points are valid. I know current mowers generally use the vacuum created by the blade to lift the grass. Maybe a pre-rake before it hits the blade(s)?
*Most nonchalant voice ever* "So I made a trailer for my automated rc tank that has two propellers with razor blades on the end spinning at incredibly high rpms just to see what happens."
Ditch the spinning blades! What you REALLY need is a scythe blade mounted at an angle up front, statically, and just drive it through the grass. Where i live we don't have flat ground or grass so i can't do it, but i bet it'd pretty cool to mount a couple of scythe blades on a FAST RC truck so they part the grass and full send it through the field. See if you can cut grass at like 50mph with a big fast 4wd truck and toss clippings into the air with a wedge shaped body. THAT'D be COOL! Thumbs up if you want to see him build this!
Currently working on making my own Tip to anyone reading this : hacknife blades are really easy to mount on a bldc cuz of the small hole on the side, but they're very brittle and break easily, so make them red hot with a blowtorch and let them cool down slowly to make the metal more flexible
A bit of a strange comment, but your ad for the motor was really well done. Managed to showcase the sponsors product in a way that was relevant to the content. Of all of the neat things that were in this video, this is what I notice...
Idea: have all the cutters at the same level, but placed in an arrow head shape. Think the front of a train, and if you can control motor rotation, have each side rotate opposite to sling the grass away from the crawler. That should boost efficiency and help clear the cuttings out of the front of the travel path.
Use 4 blades per head (make them as heavy as possible) and place them at an angle like a propeller. Put them at 2 different heights, the lower to cut, the upper to chop and clear the grass out of the shroud (optionally add a strip to the back of the top blade to increase airflow). This top pair of knives can be hidden fully inside the shroud to increase airflow efficiency and should just mulch and expel the grass. Use pairs of 2 heads and have them counter rotate, and attach them to 1 motor so you can have them overlap while never hitting each other. This will make the result look better and help expel the grass from the shroud. And most importantly, add holes in the back of the shroud where the grass can exit the shroud. Augers like some suggested shouldn't be necessary, they are used when sucking up the grass and moving it towards the vacume or for processing like in a harvester. The faster you can get rid of the mown grass the better it will work. The more airflow the better. The shape of the shroud can help, make the "tunnel" towards the exit taller the closer you get to exit as there will be more grass on those locations. Final suggestion, use 2 heads in front as wide as the crawler, later you can attach additional mowers on the side, 2 between the wheels and if you want 2 on longer arms at the rear.
Have a look at a brush hog mower. The idea of the deck is that it folds over the grass and push it down onto the blade. This allows the blade to cut and mulch the grass and anything that it cuts is thrown to the rear of the more deck. It will allow it to mulch.
Yes revisit this project please. Great idea. Whilst watching it seems the biggest problem is with grass cuttings building up around the cutters. I was wondering if something like a hoovering system could suck the cuttings away and blast them out evenly behind the machine? Once this machine has been perfected your next task will be to automate it. Then you can relax with your tea and a scone whilst watching the show.
NASA, should be funding YOU. These are very appealing and well engineered, each generation better Maybe an eye which triggers the mower bar to raise or lower so that it could mow progressively?
Great proof of concept project that is also practical and much more fun than running an actual mower. Have you considered a sickle bar approach? It would have the advantage of one motor, and the grass wouldn't accumulate in front of the vehicle. Great channel. Absolutely love your work.
3D printed sickles would work fine, would be safer that commercially made steel ones, and would be a profitable market niche. One could also explore the possibility of metallic edges on 3d printed sickles. Sorry, my Alabama is showing...
I actually use a RC mower on a daily for work mowing banks that ride on mowers and or reach mower tractor units can't get to. it uses a gnarly track system that is similar to an excavator. for the mowing head it uses a rotor with flail and roller design which mulches the grass so that It can mow through grass that has been growing for 10+ years with no trouble. the model I use is a energreen robogreen. really appreciate the video!
I remember in the movie "Honey I shrunk the kids" there was a RC lawnmower. It's funny that idea never took off as a consumer product, it would be cool especially when it's super hot out, you could sit inside the house and mow the lawn. Could have FPV camera on it too.
4:56 he says "its a lot more fun than using a normal lawn mower" honestly his grass is so long I don't even think he has ever even used a "normal lawn mower".
I love how occasionally we see the solar rover running in the background.
Its like the channels autonomous mascot
Yup. Would love to have seen a single blade mower head attached to the solar rover.
Need to keep it going as long as this channel is, would be a neat mascot/inside joke/running gag.

There are 2 ways to create RC lawnmower:
1. add grass cutter to RC car
2. add RC car to grass cutter
3. Fly drone upside down and very low to the gound

Or add roomba electronics to electric self propelled lawnmower.

I wonder if reversing the rotation on half the cutting heads would help feed the grass out and prevent clogging.
@S Grim Yes, I was thinking that too.

I don't care.
You could possibly angle the blades themselves to act like a propeller and fling the grass away

Normal lawnmower blades have a angled part at the rear of the blade which causes the chopped grass pieces to fly up into the mower deck where they are bounced around until they make their way to the outsides of the mower and ejected. With completely flat blades, the mowed grass chunks fall back into the mower blades where they are rechopped and gum up the mower
Awesome content!!!
Brian!!!!! Whats up!!!
Say hi to the" camera crew"
This is the worst video I've ever seen on this channel. He tried to reinvent the lawnmower instead of simply adding RC to a regular lawn mower (which would have been easier, cheaper, and far more effective).
While visiting Sweden in 1995, I went on a tour of the Ringhals nuclear energy facility just north of Varberg. As fascinating as the nuclear plant was, I was amazed by the autonomous lawnmower that was mowing the grass around the plant. It was manufactured by Huskvarna.
That was probably before this guy was born. I'm sure theirs actually works, too.
"No one does this" Autonomous electric lawnmowers are commercially available.
Awesome vid tho, keep em coming mate, well worth the wait for each one.
But they're autonomous, not RC :)
Most of them are also overpriced and pretty shitty.
@@TH-camAdministrator how can it be shitty if it’s cutting grass before it gets too long to be too much for the mower? And do you own one? The reviews I’ve read are pretty good on certain brands also they’re not that expensive if you’re about to spend the equivalent on a lawn mower.
They have autonomous mowers and commercially available units you mount to a full size commercial zero turn that are used for big fields. There are rc controlled units used for ditches and steep inclines as well
@@shadyknolllandscapes1781 Hey, I really like the idea of using RC units for those dangerous areas! Glad to learn something new today.
This dude finna have his whole property controlled by rc things bro….. that’s so dope I wanna try
This was fun as heck to watch, man!
This video reminds me of Uncle Shortfinger. I met him a couple of times, but I never learned what his real name was. He was our introduction to lawnmower safety.
I thought of him during the scenes with bare fingers cleaning up around the blades.
I think you've just made a " grassdozer " 3:28
As someone who owns a Lawncare company, a couple tips for you would be
1: have some sort of way to move the blade heads higher or lower from the ground.
2. Put a movable metal rectangle on the top right above the blades, anything grass taller than the wire rectangle on top of the blades, I wouldn't use it for.
3. The grass is way too tall for this to function properly, I would say the best use for this would be to use after you initially mow your yard, so it's not trying to cut huge things of grass, it only keeps it trimmed and tighty after my luge already mowed. The best application would be to keep this thing running after you've used a real mower to take down the huge tall chunks of grass, and keep this thing running after you've mowed to keep it trimmed nicely and consistently.
This is so cool. Just did a school project where I designed a similar trimmer line testing rig. Designed to cut 24" tall wheat. Would love to show you how similar it is and how I aimed to avoid some of the issues you had. Keep in mind this is a huge rig that uses 14" strips of trimmer line. Lmk if you'd like to see it
Post it public - everyone benefits!!!
AWESOME project, my fellow Washingtonian!
Ahh cool, been waiting for the new season of Black Mirror to start.
!!!
That thing will scare whatever grass it isn’t cutting 💪 sounds horrifying I love it!!!
Very cool project. I live really close to you so I know that the winter grass around here can be a serious challenge to cut. So I am super impressed at how well the mower did at the flying field.
That was great. High tech toys. Looks like a lot of fun building and flying. Nice catch.
More rotating mass on the cutters might help.
And designing the cutters to have a lot of vertical airflow to help "pull" the grass upward might also help.
Might be worthwhile experimenting with a cylindrical blade. Similar to older manual push mowers.
I can see u building a rc mower that has waypoints and mows the whole yard,, tc roomba mower, u would sell alot,, keep up the great content, love ur channel, from a 62 yo closet nerd 👍❤
Dude just get those weed eater plastic blades. Why mess around with razor blades? Potential for serious injury pretty high here. I
I think he is making up for the lack of torque with sharp blades.
Super low mass, the blade will Peter out after 5-10 feet.
Awesome job man!! 👍👍
All you need now is a camera mounted on a pole up above that you can access wirelessly and you can sit inside and mow your grass..... Food for thought!! 🤔
Subsequently banned after the "Washington Petting Zoo Incident" where the autonomous version suffered a compass error and went amok. ;-)
bro is the king of midnight entertainment
When I was a kid I cut off the tip of my finger with a quadcopter prop so this literally terrifies me.
Spinning blades that can easily be touched while they spin. Yeah. That's horrifying. I wonder if a weed eater style cutter would work better. as I feel the lawn mower blades have mass and torque on their side.
Was it some 6S beast with carbon props? I never feel any danger from 1-3S motors with plastic props
@@georgewashington1621 believe me there is. I've had the fun of grabbing into a full speed 5inch prop that was only on 2s in a wing launch scenario. Those poly carbonate props go through skin like butter
@@georgewashington1621 No, it wasn't anything crazy like that. I want to say it had 3S motors but it was a while ago. I was writing a flight control firmware for it and I made a mistake in the code that made all the motors spin up to 100% and, like an idiot, I tried to grab it to disconnect the battery. Still have the scar to remember it by.
thats sad. when i was a kid i cut the front of a lawnmower off so the blades were exposed so i could cut down taller grass. also cut a hole in the top so i could feed in sticks to chop them like a woodchipper
still have all 11 fingers
Couple things i noticed, (long time landscaper) I would suggest taking a look at commercial lawn mower decks. Look at the grass "pathway" tothe exit shoot on the right. They purposely have it all going to the same exit point and use the front edge of the deck as a channel. The smoother the spot that the grass travels at, the better it will expel. Also would suggest angling the deck upward in the front. Sounds odd, but I think if you had say 15% angle(?) on it it would help. So you would essentially set the rear at the desired cut height. This allows the front side to start cutting at a slight higher cut height and finish lower in the back. May help, and really just a thought.
One really big thing i can say is, even with a $25k commercial mower, they dont easily go through grass above 5-6" let alone if wet. Starting at like a 4" cut height would help a lot.
Also what if instead of exacto blades, try it more like a weed wacker?
Maybe extend the top cutter out further and half the distance above the bottom one.
You need fingers on the front, like a corn combine.
This! Make em barbed (like arrow heads) to help direct and control the tall stalks. A RC lawnmower that cuts a lawn regularly as it starts to grow in shouldn't have issues with regular trimming. Its that "I'm too lazy to cut my lawn so its massive now." kind of cutting that will have issues.
And some gaps at the back, for the cut grass to leave the cover.
The problem with this idea is that while corn is planted in fairly symmetrical rows, and thus grows as such, grass doesn't grow in any semblance of order. The fingers on a corn header just help to direct the corn onto the cutters and keep it from folding away; meanwhile, on a self-propelled mower, there's a big wheel like on a wheat head.
@@cbpercy06 sounds like you have some farming background and your points are valid. I know current mowers generally use the vacuum created by the blade to lift the grass. Maybe a pre-rake before it hits the blade(s)?
It's so small for cutting the grass but it's very best experience!!! 👍👍👍❤️
*Most nonchalant voice ever*
"So I made a trailer for my automated rc tank that has two propellers with razor blades on the end spinning at incredibly high rpms just to see what happens."
Got that too. Steven Wright of inventing.
It's oddly satisfying watching this cut through grass.
should have just used a weedeater head, would have made a pretty effective mower. still really cool project though
Ditch the spinning blades! What you REALLY need is a scythe blade mounted at an angle up front, statically, and just drive it through the grass. Where i live we don't have flat ground or grass so i can't do it, but i bet it'd pretty cool to mount a couple of scythe blades on a FAST RC truck so they part the grass and full send it through the field. See if you can cut grass at like 50mph with a big fast 4wd truck and toss clippings into the air with a wedge shaped body. THAT'D be COOL! Thumbs up if you want to see him build this!
34 seconds ago? i've become feared amongst men
Wow wonderful very interesting video
Love from Pakistan 🇵🇰
What about a mechanical push powered mower? The old school cylindrical ones with bent metal blades. Then you can eliminate 4 motors and save battery
Imagine how quiet that would be with a vehicle as slow as the solar rover he’s got.
Honestly, he should have just added remote control to a regular gas powered mower.
Nice Rock Crawler Mower
"Because It never stops raining here in Washington" Lol I can say that is true.
"make mowing fun AGAIN"
Should of been the title...Cool stuff!!!
Those lines are my father’s worst nightmare.
Just wait t’ll he sees it, he said he was getting some milk, he’ll b rt back.
probably my new favourite channel
Definitely don't wanna walk barefoot in that field now XD
Now buy a riding lawnmower, and strap a flight controller to it.
I would've bolted some steering onto a real lawn mower and power drive the wheels.
This would be way more effective. He tried to reinvent the whole thing, from the ground up and did a major fail.
That was impressice! As someone who has thought about making an RC mower so I could turn the drudgery of mowing into a video game, ME likey!!!!!!!
yo i was just thinking u should do this
This seems like a cool new way to make Crop Circles!!!
Please revisit this topic
Currently working on making my own
Tip to anyone reading this : hacknife blades are really easy to mount on a bldc cuz of the small hole on the side, but they're very brittle and break easily, so make them red hot with a blowtorch and let them cool down slowly to make the metal more flexible
reminds me of my custom chariot back when i was a gladiator in 270 BC.
Boomer
Ah the good old days.
A bit of a strange comment, but your ad for the motor was really well done. Managed to showcase the sponsors product in a way that was relevant to the content. Of all of the neat things that were in this video, this is what I notice...
you should make a dedicated RC lawn mower with the best type of mower head that you can think of and have it do a way-point mission!
Damn that thing works pretty good for what it is. Nice job dude.
Please make a sequel this was very entertaining!
Your Voice overs sound just like The Outsider. Great content BTW.
Idea: have all the cutters at the same level, but placed in an arrow head shape. Think the front of a train, and if you can control motor rotation, have each side rotate opposite to sling the grass away from the crawler. That should boost efficiency and help clear the cuttings out of the front of the travel path.
With all your autonomous vids, this begs for it!
That is literally the funnest and scariest looking thing I've seen.
Комментарий в поддержку канала и ролика, а также труда мастера.
That's literally more capable than my mower. Tall wet grass like that and it's cutting that well. Awesome
Use 4 blades per head (make them as heavy as possible) and place them at an angle like a propeller. Put them at 2 different heights, the lower to cut, the upper to chop and clear the grass out of the shroud (optionally add a strip to the back of the top blade to increase airflow). This top pair of knives can be hidden fully inside the shroud to increase airflow efficiency and should just mulch and expel the grass. Use pairs of 2 heads and have them counter rotate, and attach them to 1 motor so you can have them overlap while never hitting each other. This will make the result look better and help expel the grass from the shroud. And most importantly, add holes in the back of the shroud where the grass can exit the shroud. Augers like some suggested shouldn't be necessary, they are used when sucking up the grass and moving it towards the vacume or for processing like in a harvester. The faster you can get rid of the mown grass the better it will work. The more airflow the better. The shape of the shroud can help, make the "tunnel" towards the exit taller the closer you get to exit as there will be more grass on those locations. Final suggestion, use 2 heads in front as wide as the crawler, later you can attach additional mowers on the side, 2 between the wheels and if you want 2 on longer arms at the rear.
Have a look at a brush hog mower. The idea of the deck is that it folds over the grass and push it down onto the blade. This allows the blade to cut and mulch the grass and anything that it cuts is thrown to the rear of the more deck. It will allow it to mulch.
Yes revisit this project please. Great idea. Whilst watching it seems the biggest problem is with grass cuttings building up around the cutters. I was wondering if something like a hoovering system could suck the cuttings away and blast them out evenly behind the machine? Once this machine has been perfected your next task will be to automate it. Then you can relax with your tea and a scone whilst watching the show.
NASA, should be funding YOU. These are very appealing and well engineered, each generation better
Maybe an eye which triggers the mower bar to raise or lower so that it could mow progressively?
Awesome job my RC brother
I have that Fusion in my Axial Wraith. Love it. Great low speed control
You need bigger blades. Thanks for the vid! I love anything RC!
Great proof of concept project that is also practical and much more fun than running an actual mower. Have you considered a sickle bar approach? It would have the advantage of one motor, and the grass wouldn't accumulate in front of the vehicle. Great channel. Absolutely love your work.
3D printed sickles would work fine, would be safer that commercially made steel ones, and would be a profitable market niche. One could also explore the possibility of metallic edges on 3d printed sickles. Sorry, my Alabama is showing...
This is just cool, clever and creative!
I actually use a RC mower on a daily for work mowing banks that ride on mowers and or reach mower tractor units can't get to. it uses a gnarly track system that is similar to an excavator. for the mowing head it uses a rotor with flail and roller design which mulches the grass so that It can mow through grass that has been growing for 10+ years with no trouble. the model I use is a energreen robogreen. really appreciate the video!
I remember in the movie "Honey I shrunk the kids" there was a RC lawnmower. It's funny that idea never took off as a consumer product, it would be cool especially when it's super hot out, you could sit inside the house and mow the lawn. Could have FPV camera on it too.
Steven King could make a scary movie about that mower with razor blades chasing down 3rd graders in science class.
4:56 he says "its a lot more fun than using a normal lawn mower" honestly his grass is so long I don't even think he has ever even used a "normal lawn mower".
