Newer than new. Get those nubs off the tires. These tractors are made to work. ( notice I can say that without a smile )
Greg; I need a favor. How about some pictures of the steel rack in the back ground ? I have the base made for mine, ( 3' x 8' ) but haven't made any uprights or brackets. Now that you are using it is there any changes you would have made ? Is it moveable with casters ? After stacking my pile of misfits on it I think it would be too heavy to roll.
