Hi! I have a yth20k46 and I have to cut some steep hills. After learing that the thing had noooooo traction I went to tractor supply and bought some agracultraul tires. like the ones in the link below. THese things are great! I rairly get stuck any more, only problem is that the suck in the snow or on wet plywood. good side is they cost about 60 bucks a peice!
