i been working on one for a friend, and man belive me that thing works harder than any thing i ever saw, except A full size dozer. this little machine came to me for repair, it was useing oil he said , looking under it it the bottem seal (oil will pour right out on the ground ),funny thing is he never noticed where it was comming from. so it needs the engine pulled to fix ,alot of hours here doing that recently ,now fixed i tried it out in my yard and now i dont want to give it back to him at all,i offerd him 400 and he laughed ,(where if anyone knows can i find one of these little dozers ), i dont even care what shape its in, it would be a restoration ,something to start with ?make and model are not important either. there aint many of them around. I dont know why they didnt catch on ? they work much better than any wheeled tractor i ever saw ? timbo
