The lift linkage on my tiller bent. I straightened it once. It bent again. I decided it was from loading and unloading. The tiller hits the ground and bends the linkage when the tractor starting up the ramp, or coming down for unloading. Figured a slot would help. It did.
This worked good this spring while hauling the tiller to my uncle's place about 34 miles away where we "share crop" potatoes.
