  • / Gravely Promaster 152, 23HP Kohler Engine - Blades Stopped
Just finished up yesterday evening with this year's grass cutting, and on the last round, the blades stopped turning, but all else worked fine (forward/backward motion, engine). Cutting a lot of leaves but little grass this time of the year. Had been cutting for about 5 hours or slightly more by then. First thought it was a broken belt(s) but all belts seem fine on the mower deck. Cranked mower this morning and it started just fine, but blades still won't engage. This was the 13th season for the mower after buying new in 2008; almost 900 hours on it. After looking over operator's manual and parts manual, wondering if it could be PTO switch, relay, or electric clutch? Anybody have recommendations on what and how to check for.... circuitry, etc. (I'm way mechanically challenged)? Any thoughts/similar experience are appreciated in advance. Would like to fix it before I put it up for the winter.
