Last year I built a brush cutter using an old 172cc lawnmower engine. Mounted it on aluminum plate that I got from a metal recycler. It’s 32”x32”, with a piece of aluminum on both sides next to the mower blade to direct the brush in the front and out the back; running front to back and extending down about 6”. The unit mounts on the side of my ATV cart, and hangs by 2 chains from the pipe at the corners of the cart. This allows me to adjust the height that it is above the ground. It works perfectly for cutting brush (alders) up to 1/2” in diameter. I intend to post a vertical of it but have been procrastinating. I’m not much into social media or TH-cam. Only created my channel because I have people asking about my brush cutter and it was the easiest way to get the information to them.
I was able to watch all three of the videos and have a much fuller comprehension. You might research and patent any ideas that are unique to your "final" design. (You know you are going to find more little improvements that might crop up, plus the fact as the machine itself ages, stress points will see needs for gusset welds and other reinforcement welds... stuff like that. Welding up some eyes on quick release pins for adjusting points might be of interest? ) I really liked the way you saw through your initial problems and those guards for deflecting the alders away from clogging up the inner workings, the tire, as you saw them, as well as the multiple adjustment points, all well thought out, plus internalizing the bearings and the ease of sharpening the cutters... really good work. Custom build a few for income from a side business?... All I can say is keep up the good work!
I’m using this as inspiration for a front mount unit for my Kawasaki mule. I plan on using an old hot water tank for a shield and chipper blades from a lumber mill for blades. What are the first problems that come to mind I may encounter with my project? I was a machinist for 12 years so I have the skill base but no machining equipment lol
After working out the bugs in my design, most caused due to lack of skills and knowledge; here are some things you need to consider: -Try to keep the weight down without sacrificing strength. - protect the cutter shaft bearings from grass build up that will heat up and burn out the bearings. - use a good grade shaft. - my biggest problem was keeping the cutter shaft straight and balanced. Because of that problem I can’t spin it any faster than 2400 rpm and had to find the exact sweet spot of rotational speed. - if you are trying to mulch rather than cut, the way my cutter does, you may need more power. FYI: if you go to my TH-cam channel and look at all the BrushBusteR videos you will find info on how I built it, the specs and problems to avoid. Make sure you post a video of your build and send me a link. Right now I am looking at using a old mower deck, (with mower engine and blade) that I can drop in my quad cart frame when I want to use it. The purpose being to cut the new brush that grows in my cabin trail/road every year. It can reach 2 to 4 feet in one summer. My BrushBusteR won’t cut it because it is to flimsy for the blades to bite into. Which is a major failure in my design.
@@huntcampdiysolutions8239 I will surely keep you in the loop. Thanks for the tips. I have a page as well for my camp and all that I do for it. Check it out Adventures at Dreamland I’m a true scavenger so freecycling as much as I can is almost like a sport lol

A lot of work, been meaning post that project. My brother’s TH-cam Chanel: He also has videos of his 300Zx and a 60’s 4x4 GMC pickup. th-cam.com/video/Ku8Hni_LXlQ/w-d-xo.html
Awesome solution ! Been looking for something this rugged for years. Please post an email address in your "about" so I can reach out and discuss purchasing your last prototype. We can test drive it for you, film results and share with you
Good work! I think I’ll build one. Thank you for the information!

You should put it out there. I’m sure lots of folks would be very interested to see it. A lot of us appreciate the ingenuity of others.
Very well done.
Thanks much.

Mild steel, that is all that I had access too

What steel did you use for the blades, and what thickness of metal?

What size motor did you settle on? are the pulleys still a 1:1 ratio?
Go to my TH-cam channel: all that information is in one of the other videos
