wow, this blows my mind!!! I have been digging up my entire back yard after removing the humoungus oak trees and removing all the roots, doing it all by hand(shove, pick ax&chain saw) I finaly remted a stump grinder...wish i had rented a track how... Ive been using my 4 wheeler to haul dirt&debris. on a slide and small trailer/cart I made from old truck bed liner& scrap,2 "J" bolts for axles & old pnumatic dolly whels&tires. but yester day i was thinking how I could make a "steam roller" for my 4 wheeler....somehow i dont think it will be quite this elabrate..I had thought about adding a sproket to the axle and running a 12" carbide tiped circular blade through the ground to cut roots...but turning would of been a issue so.. the shovel was happy to step up. I should probably rent a wacker...tamper? ground pounder!!!
