I have a 18hp Toro/WheelHorse lawn tractor (one-year old) that doesn't get
enough traction for mowing my yard. I have popped the bead on the rear
tires and poured in as much anti-freeze/water mixture as I could get in
them. This helped some, but I still don't get good traction on my hilly
yard.

My grass isn't unusual-- just fescue/blue grass, but my yard is pretty
hilly. The frequent wheel spins when turning or maneuvering, or going up
and down hills is tearing up my grass. Any ideas?

Thanks
