PTO switch or PTO clutch?

    For quite a while (2 years or more) when I pull up the PTO switch sometimes I get a hesitation before the clutch engages. To get it to engage I have throttled up or down to change RPMs and this has worked. Also when the switch has been engaged I have noticed that sometimes if I start going forward this has also helped in getting the clutch to start. Now the clutch will not engage at all, even when i try my past successful fix its.
    So any idea as to whether it is the switch, clutch or something else that could be wrong. Thanks in advance.:)

    first,on the input side of switch, then on output side of switch. If you have correct voltage, on both sides of switch, when it is on, proceed to clutch itself. If clutch has a good ground, then its probably the clutch. Some clutches have an air gap adjustment-check your manual. While you are near the clutch, visually inspect for bad outer bearing, sniff around, too sometimes you can smell a burned one before you can see it!:waving: :waving:

    Sounds like your air gap is too wide.

    It was the PTO switch. Clutch works fine. Thanks for input.
