    PTO cuts off at low speed when using tiller

    Running a 445 garden tractor with the 450 PTO tiller attachment. When I was tilling today the PTO would cut out at low speed even though I had not come to neutral. It seemed like I had to go too fast (for the tilling I wanted to do) for the PTO to stay engaged. I am aware of the cut out safety feature but the cut out problem today seemed excessive. The soil being tilled today had previously been tilled a few weeks back so there was no real load being applied to the tiller. My son complained that the PTO would cut out when he tilled that first time and I just thought it was his driving! Now I believe him. Come to think of it, this also happened when operating the front-mount snow thrower this winter.

    Am interested to know if anyone has had this similar problem and what the remedies were.

    Thanks in advance.

    When you say cut out at low speed. Do you mean the engine is running slow or the tractor is moving at a slower ground speed?
    By safety feature do you mean the PTO shuts down because of high engine temperature?

    Have you adjusted the PTO recently. With putting a load on it if not adjusted it could cut out. I have to do the one in my F525 about every two years.

    Not the high engine temperature feature. I should have been more precise. When you release the forward pedal to go into 'neutral' the PTO cuts off by default, right? Well, for me, I'll be travelling at a slow speed with no significant load on the machine (no overheat either) while tilling and the PTO only just shuts off.

    Thanks, I'll look in to that as well.

    I don't believe that the PTO should shut down just by letting off the forward pedal. Essentially putting the trans into neutral. This could be part of your problem. Now if you press the brake or reverse pedals while the PTO is running it should shut down. Maybe the linkage or safety switches are out of adjustment. The brake and reverse pedals should both have one.

    Thanks, H-D dealer dude. I found the safety switch assembly that's mounted to the chassis on the pedal side of the tractor. Moved the switch back about 3/16" and retightened. Ran the tiller in the garden with no "shut off" problems at all. Much appreciated.

    Glad you got it working. Always nice when you don't have to buy parts.
