Every tractor with a 12volt pto clutch requires a tight fitting belt. Tensioner must be totally function and correct spring used. Tensioner pivot point will wear egg shaped and cause issues. Belts don't stretch, the width of them deteriorates and allow the belt to be too deep in pulley grooves...then it is loose.I'm almost at my wits end..I have a used 2010 LA140. I have replaced the PTO clutch, all 4 rims/tires, PTO switch, and neutral switch.
Got it running smooth, started cutting my lawn, had to disengage the PTO to back up..started forward again and pulled the PTO to start cutting...nothing tried turning the PTO on and off a couple times..I can hear the clutch engaging but no mower..any ideas?
Tractors without 12volt pto clutches are loose when disengaged and tightened by the tensioner which is controlled by a manual lever that moves a cable attached to the tensioner. Again the tensioner pivot point can become egg shaped and cause issues.
