Vinylguy 4,692 #1 Posted July 6, 2019 My PTO does not stay engaged all the time. Once in a while it flips out on its own. Is this a tension adjustment or something more sinister? Nos deck and mule drive Share this post Link to post Share on other sites
JAinVA 4,638 #2 Posted July 6, 2019 Trunnion at the PTO end needs to be rotated ccw a few turns most likely.I would try that first. Share this post Link to post Share on other sites
peter lena 9,318 #3 Posted July 6, 2019 agree with the trunnion adjustment, it has to be free to go past stop and hold in place, pete Share this post Link to post Share on other sites
Vinylguy 4,692 #4 Posted July 6, 2019 In other words it may be too tight ? 1 Share this post Link to post Share on other sites
Vinylguy 4,692 #5 Posted July 6, 2019 Noticed that after it warmed up it seems to stay engaged and maintain full blade speed. No slipping Share this post Link to post Share on other sites
JAinVA 4,638 #6 Posted July 6, 2019 (edited) If it is to tight then it won't snap into place. You also will see a large deflection in the clutch rod.If you have never adjusted the trunnion in the past, then normal wear will cause the clutch rod not to stay locked into place.Once warmed up heat from the engine causes the clutch rod to lengthen enough to keep the clutch engaged.

squonk 43,952 #7 Posted July 6, 2019 Give it a couple of turns to loosen it up and try it Terry. PTO lever has to get X number of degrees past center to lock. You're prolly a couple of turns off. 1 Share this post Link to post Share on other sites
Cee245 846 #8 Posted July 6, 2019 I've had to adjust mine in the past for the same issue. I loosened it full turns and it hasn't done it since. However, does anyone know if its normal for the pto to turn seemingly full speed while NO attachment and/ belt are installed? When this happens, I turn it off and the pto spins for a while afterwards Share this post Link to post Share on other sites

Vinylguy 4,692 #12 Posted July 7, 2019 I guess the Toro dealer didn't check the idler pulleys when installing my Nos deck. The right side pulley was black from heat of the belt sliding on a stuck pulley. After removing said pulley it has a 1 inch shim and one washer But was not enough for the pulley to clear the deck bracket pictured below. I was lucky enough to find 2 washers to add to the shims And now the deck spins as it should. No wonder the deck slowed in taller grass. Now it cuts through the stuff stuff without any problem. Do need to get a longer pulley bolt though. Probably take one washer out and still clear the bracket. Thanks for all the help guys. 1 Share this post Link to post Share on other sites
