Today, I noticed upon acceleration of either side at low idle caused a chattering sound and while watching either tire they seemed to be kind of jerky. I throttled up to WOT, and I could still hear it but not as bad. Any advise would be appreciated.
Scag recommends 24 month/400 hour drive belt replacement and 500 hour hydraulic oil and filter change.
At every drive belt change I have had to replace the smaller drive belt tensioner pulley due to dry running. Next time I'll replace both pulleys and the tensioner spring.
