[QUOTE=Sam Mac;440471]Wheels are supposed to spin in opposite directions when you spin 1 wheel, that how a diff works.
I understand this. But when I installed everything into the tractor the first time around, with the wheels mounted on the hub and tires touching concrete, the tractor wouldn't roll forward or backward when I tried to push it. The rearend was locked. The second time around after reinstalling everything, it rolled fine when pushed. Maybe this contributed to it not working the first time. I wonder what was hanging it up? The pump shafts spun freely by hand before mounting.
