Pto saw or gas powered saw attachment

jordan2140 · Feb 10, 2018

Who has fabricated their own pull behind tree saw? Thinking of converting a brush hog to a saw blade or adding a harbor freight gas motor and blade to a brush hog shell. Would have to relocate the drag wheel and maybe add one in each corner.

I saw a homemade on Craigslist a while back but having trouble finding plans or videos on diy attachments. Would be running on a lt245dt. I know they have industrial ones that run $5k but that cost more than my tractor. See my sketch for what I am thinking!

don't forget added cost of ROP and limb cage to put over the cab for the times the thing falls back on you. Limiting the size of the gap for the exposed blade will help keep the person who gets this unit after your gone from cutting down things too big I guess.

could maybe mount a gas chain saw to be the saw.. though probably cant get low enough that way.

Haha. My wife makes me wear a helmet anyway.

I was thinking 4 to 6 inch trees max. Most are mesquite and not too tall but are full of thorns!

How about adding a spring loaded guard on the top side of the blade. This will also allow the blade to cut the tree without having the blade exposed.
Literally a few pieces of angle steel, some bolts and a spring or two, that as you back into the tree, it gets pushed forward by the tree, or swings to one side on a pivot point, while the blade cuts.

One similar to this would be safer and more practical, I think. Easier to fab up with less moving parts. Start off with a wore out grader blade you can probably get from you county maintenance dept, or local scrap yard.

Could adapt to 3pt.

I’ve been thinking of a hydraulic tree shear to fit on the backhoe

I would lean toward gas engine. If that pinches quick, your tractor's PTO is gonna take a beating....

A buzz saw blade might work, but they're not designed to have the pressure from weight of a tree on them as it cuts through. Seems tree saw blades are much thicker than a buzz saw?

I'd prefer the PTO with a good clutch over the engine. And do think of safety if you attempt this!

Other than the obvious cool factor, is there any reason to not just use a chainsaw? It seems like for 4 in to 6 in trees a chainsaw would be faster, safer and cheaper. Just curious what the motivation is here, it might help us come up with ideas for you.

I think he mentioned thorns, he might not want to get closer then 6' to the trunk and a 6' bar would be a lot of chain saw.

I would still make a hydraulic powered or even PTO powered chain saw on a 3 point, It would be 1000% more efficient!

All you would need is a big bar and chain and drive sprocket and make it all up.
I've even seen buzz saws that use a chain saw chain as there cutter wheel, very effective.

One advantage to doing this is that because he's using it on a three point with a
very uncontrollable rear crawl rate (would work much better with a HST tractor), you could make the cutting bar/wheel be spring loaded or hydraulically controlled to help with the cut pressure and rate.
