Deere 777 Ztrak from 2005 I think. The mower deck drive pulley bolt has sheared off twice in the last 40 hours. It happened right at the end of season last fall, replaced it with new from dealer, and now it just broke again after about 15 hours of mowing this year.
Has anyone ever seen anything like this before? The bolt is stamped 8.8 and the pulley bearing feel pretty loose, it will spin 4-5 turns on my finger so I think that means no binding. Any ideas appreciated. Thanks....
