This old tugboat captain finds your rigging skills very interesting. The way you jump around from limb to limb sure caught my breath in my throat. Well done as usual.
Excellent narration and execution. Being able to plot out predictive trajectories based on simple cut strategies in such heavy wood definitely shows the finesse of a caring professional. Disaster mitigation is always appeciate, but seldom commended. And kudos to the little Husky that can. It's bite is bigger than it's bark.😊
Super good dude! I like how you were disappointed at the two tiny face chunks that dropped in the neighbors yard. Pretty dang awesome in my eyes. You guys are great!

August...I think a lot of credit for the "power" of your 540i is the sharp quarter-pitch chain. I can't imagine how much wood a 200T would cut with the same bar and chain!
August, thank you for ALL of the valuable information you give us “TH-cam” you are helping me learn more and more about my hobby. Your friend from Alabama 😂 Avery
I really enjoy your videos for the simple fact that you explain what’s going on as far as how everything is set up as well as what your thinking and why you do your rigging the way u do it
It's a pleasure to watch you thinking "on the fly", August! 😉 Using EVERY tree limb to your ADVANTAGE! 🤯👍 Who's threading the needle with the Vermeer? 🤣👏
Great channel August, i like how your always one step ahead, thinking about the customers property, safety of your men and yourself. How to make it more efficient, if you did it this way or maybe that way. You always got a plan, and you share it with us. I find it very interesting ,thanks for sharing ,stay safe. M.
Just wanted to say "thanks " for educational content. I'm not a tree guy, but used a directional face cut and a cripple cut to pull a small tree exactly where desired.
Thanks for coming back to get us. 8-) I enjoy watching the crew and you working. Hope the crew / family and you are doing well. Take care - Be safe and God Bless.
Brilliant coverage, good angles, the go pro gives us up close shot's and real close shot's so thank's for the effort. Every branch go's exactly where you want it to go. . Looking forward to the next video...
I have no _'need',_ for a saw like that (can't justify the expense, for the little amount of cutting, I do) - but I _'want'_ one! lol _I covet thy saw, saw envy?_ Anyway, been up since O'dark-thirty, having coffee, and watching me some trick, tree-work! Have a great day, all-y'alls! 👋
This old Oak have always still great pronged Blister. Is the USA Sort, the Austria Sort have round and small Blister! You to see by the Cut maximum. The to let off from the Arm very good to aim. Thanks for all Your Spitz class Videos! Greeting 🇦🇹💪👍
BEAUTIFUL WORK! So much better than cutting pieces off and letting them crash to the ground SOMEWHERE. The part of this that is not as obvious is the masterful handling of the rope by Jeff to get the branch smoothly to the ground in exactly the right place and perfect coordination with the cutting by the climber August.
Good stuff! I’ve thought about trying out a battery top handle. My buddy has a Husky and it works pretty well, even on large removals. I believe Echo came out with a battery top handle also.
With every piece that's Rigged is a very well calculated execution of professionalism at its finest! Big ups to you and the crew August! 👏🏼 Jeff was smoking that rope as well! 💯💪🏽🤙🏼 Yall boys be safe and keep them coming! 🙏🏼
I think it would be hilarious if you put a Fisher price label on your battery saw. Do not get me wrong. I think it's a great saw I just think it would be funny to read the comments.
My dad was raised in the PNW and used a chainsaw extensively on PNW soft woods. Decades later (late ‘60s) he was using a chainsaw on a 3’ diameter OAK tree at my sisters place in Atlanta, Ga. He was continually complaining about how the chain would dull SO fast… It would cut beautifully for a couple minutes, then quickly dull down. He complained he spent as much time touching up the chain sharpness as he did sawing. That was a completely new experience for him. Hopefully the metallurgy has improved LOT since then. It was a rental saw, which may be a factor….?
Had the opposite problem in WV, all my stuff cut nicely in oak, locust, poplar and then one day (5) 100’+ white pines, fortunately my chainsaw guy had chains he recommended and they worked.
sounds like it could have been cheap chains or also using a dremel to sharpen. Non Rpm adjustable dremels will sharpen at too high of speeds and compromise the steel tooth on the chain, creating that exact condition. Cuts great initially but not for long.
I remember your first electric saw video.. I still say you may appreciate the back handle, more than the top. It relieves the torgue on your elbow, and gives more reach. Great videos, man.
Do you climb, yourself? I’ve been up in trees with rear handle saws a bit, but reach for a top handle (echo 355T) every time it’s large enough for the job because I find the ergonomics so much better.
I try to use my 2511t as much as possible then the355t i may get a a husky or echo tophandle battery saw eventually good job August you have created a crew that loves the work and are very productive have a good one
SO, you HAD an 'inkling' cut tree interest desire that your subconscious mind pursued and then a 'couple' appropriate, knowledgeable "MENTORS" took over your mind and you done good, boy! PLEASE send them a 'thank you' card from the "103K" of US!!! and Thank You!!!
I've got 20 acres full of Black oaks. What we call black jacks . It is some seriously heavy wood . Chains dont stay sharp very long cutting that stuff.
Be great to see you try more battery saws, they're the future. There are new more powerful stihls, a back handled saw and a top handle, msa300 and msa220?
Battery powered saws make sense for some jobs. Just like cars. It just don’t like them being crammed down our throats by the politicians who own stock in the companies.
I've often wondered if you could use RC car type battery packs in that saw. 15min charge time and fairly inexpensive. I wonder if that would be worth having a look at. Bsafe broski.
That battery saw is impressive i might have to try one out bet its very noce when in comm with the guys compared to a 200 or a big saw haha awesome looking removal
I couldn't use that electric saw. Obviously it's more than good enough for the job or you wouldn't have it, & I am not too stubborn to try new things. But that sound it makes reminds me too much of a dental tool, would be getting weird chills mid cut all day. 😅
chuckling, good morning August. Question...ever get weird cramps in your toes after a day in the tree? I get what I call "Monkey Toe" . In stead of cramping curled up, they cramp the opposite way, straightening out. Weird huh? I got a laugh out of you saying "well, now ya know" about the big limb... nice to have coffee with your video. Thanks. George.
Since you started using the battery saw and since my son-in-law's gas saw died, i've been thinking about getting him a battery one. But I've seen on a homesteading channel other saws used with poor results. I don't want to get something that ends up being as useless as his leaf blower is but, as someone else commented, there's a lot out there now. He would mainly use it to cut off branches and maybe down the occasional small to medium size tree. Any suggestions would be very helpful! Love your videos and very happy to be one of your subscribers. 😊👍
@@robinrummel1359 that’s an entirely different story. I barely ever sink a saw into a stem less than 18” thick down here in TN, so I tend to think in those terms…
I've been wondering for awhile about that saw but I haven't heard you say much about it other then it's a husky with a panther 1/4" bar and chain. Can you give us more specifics, like what model and have you done anything else to it to make it better? Seems to be the bee's knees, super interested in getting myself one, thanks.
August, I have a TH-cam video offer for you. Come to West Virginia & give me a crash course in tree climbing/removal. I'm very familiar with this type of work coming from landscaping. We do some removals but only if they're away from structures we could damage from a falling tree. I'm 51 so our age is fairly close. Anyway, something maybe fun & challenging for you!
the 540iXP is a LOVELY saw. We have one with the standard ( Not Top) handle on it and it cuts amazingly well for it's size and the funny sounding "engine" August - I notice you have that Panther(?) bar on it and I suspect a different chain than the kit comes with - could you share those items by chance?
How many batteries did you go through in a day’s work & Can you talk about it in future episodes? Also is the saw safe, will it lock up as it should as those fibers try to bind it up. I have a Makita XCU04 32 Volt, (takes 2 18V) and it’s very safe, batteries charge up within 30minutes.
Correction: charges in less than an hour for a 5AhBattery on a double charger also 36V not 32V. The 2Ah batteries are lighter and charge faster, but get used up fast too. There is a 6Ah battery & it charges in about an hour. The Makita 18V X2 LXT Lithium-Ion Cordless 16″ Top Handle Chain Saw Kit (XCU09Z 2-BATT) is designed for up there in the small branches. Would love to see some honest comparisons.
You’d want a redirect to be above a drop zone, not sure what swing you were referring to but guessing it wasn’t a problem and actually placed the piece above the zone? Redirecting on the stub and then cutting the stub to allow the bundle to complete a lesser swing can be useful sometimes.
I hate the plinko pieces lol iv had some crazy luck or just poor choices on my part but I wouldn’t have ever thought they plinko the way they did or in one case as far as it did lol you live and learn but iv got this fear of short and stubby pieces nowadays lol
Looking at the Makita 36v Top Handle (XCU08z), as I already have 10 Makita 5Ah batteries. As a homeowner, I can’t see buying into the Husky battery system, even though I’m a Husqvarna guy, I’m also a Makita guy, and I just want one battery system. How is the weight on that thing?
I have that makita saw and it is a workhorse. It may not be as strong as the husky (have no way to directly compare) but I would think it is very close...

August - I notice you have that Panther(?) bar on it and I suspect a different chain than the kit comes with - could you share those items by chance?
They sell them at monkeybeaver.com. Panther bar and 1/4 pitch chain conversions for most of the popular top handle/ climbing saws.
T540i XP - no doubt, best battery saw. I just need to get your narrow kerf bar. The high rpms will chew up and spit out some wood!
The panther bars are soft and don’t last nearly as long as a factory one, but the way 1/4 pitch cuts makes it totally worth it.
I agree 😁

Which battery saw are you using? It looks very capable.
It’s a husky t540i i believe
Crazy big tree
How much does that battery saw weight? Is it comparable to an ms201T or more like the small echo 2510?
August, thoughts on the 500i? You seems to be loving it but I’m curious if it’s worth the $? Thanks for all the effort in bringing us along!
Favorite Saw ever. No joke. Nobody paying me to say that. Nobody giving me jack diddly squat.
The batteries saw does good but the 2511 sounds much better
You could always use a sling as a redirect point to stop the swing
My goodness you must be quite new to the channel 😊
You’d want a redirect to be above a drop zone, not sure what swing you were referring to but guessing it wasn’t a problem and actually placed the piece above the zone? Redirecting on the stub and then cutting the stub to allow the bundle to complete a lesser swing can be useful sometimes.
Do you shut the saw off after each cut? Do you find it extends battery life?
I don’t usually but ya it does

Depends on the sweep

Looking at the Makita 36v Top Handle (XCU08z), as I already have 10 Makita 5Ah batteries. As a homeowner, I can’t see buying into the Husky battery system, even though I’m a Husqvarna guy, I’m also a Makita guy, and I just want one battery system. How is the weight on that thing?
I have that makita saw and it is a workhorse. It may not be as strong as the husky (have no way to directly compare) but I would think it is very close...
I’ve used both. Husqvarna is on top.
Get as large a AH battery as you can. It will last longer and have more torque.
