I know this is old, but I just found it. I have the same problen and don't want to spend $170 on a new roller. I'm going to JB weld the loose, ragged cover back in place. Would think someone would make a slip on rubber sleeve as this must be a common failure. The metal roller is in perfect condition. I mow 15 acres 26 times a year and have done so for 11 years and the only maintenance has been greasing, cleaning, sharpening, couple of blade replacements and two belt replacements. Been waiting for bearings to go but they have held better than I thought possible.
