Check for to much play (side to side all the way around (360)) between the shaft (wheel) and the cylinder (mount). If there is you may have to make a new mount or use bushings to fix it from locking due to tipping from vertical. Also make sure the springs are under some tension always.

The castor wheels arent supposed to be touching the ground while mowing.............only there to keep you from scalping the ground.

You are correct the 60 model for the 420 does does run on the ground. Been that way since it was brought and setup by the JD dealer almost 30 years ago. That why the wheels are very large compared to other decks and have bearing/grease zerks, and the mounts also have grease zerks

Needs bushings. Check for bent shafts too. MOST big decks use castor wheels to adjust deck height and they are meant to touch the ground... and the parts will wear with use.

Yep, slotted shim washes, which you move from below the mount to the top of the mount and vice versa to adjust the height.
