John Deere 42' cutting deck
JD LA 135 SE 22HP rider with 42" deck.
It's a few days past a year old with under 60 hours.
Never left outdoors, in very good condition.
I use air blower to clean up after every use.
At 45 hrs I pulled the deck out to clean and lube. I noticed some wear at points in the plastic spindle pulley covers. I saw no way to adjust the position of the covers.
After cleaning and greasing, I put it all back together. Noticed a change- I could smell the hot rubbery smell of the belt. I did visual checks, saw nothing wrong.
The belt heating became worse with each use. I pulled the deck a few days ago and found the belt seriously wearing along part of its length (not uniformly as if constanly rubbing). Without the belt, the spindles turn easily with no bearing noise or serious runout.
Now the belt is so bad, it actually rolls over in the pulleys and jumps off the engine drive pulley. I cannot cut grass with it now.
Everything on the deck looks good as new, except for badly worn pulley covers.
Before I replace the belt I wonder if there is something I can do to avoid this problem?
My new belt is John Deere replacement part GX20072
