Well, I used to cut the trees level with the ground. Then I started smacking the stumps with the plow and noticed I was pulling them up. So, I now save time by just plowing stump and tree together. A 4 inch tree is probably too big. I hit a stump in 3rd or 4th gear before and turned my plow into spaghetti,,, and I flipped over the handlebars!

Btw, my plow is a 1/2 inch thick sheet of steel. Not these 20 gauge (or whatever) steel plows you buy for plowing snow.

 

If you need some parts for your quad let me know. I have a 86 that is complete. The only thing that is missing is the driveshaft. They can be had for really cheap. Let me know on a decent price.

thanks
