    Was told by a friend that you should only turn on your blade PTO with the engine set to low. I Have always thought you should give the engine full throttle. What is the correct way or does it not make a difference?

    This is on a Toro ZTR

    Half throttle is probably best. But we all know that while mowing and in a hurry we engage it at full throttle most of the time.

    I agree with khouse on half throttle, Had a customer keep coming in with snapped PTO belts, I couldn't find any reason for it. After drilling the customer I found he had been shutting the blades off when going across his driveway then turning them back on at full tilt.
    It really is a shock on the belt engauging at wide open.

    I just purchased a new Ferris IS1500 with 52"deck/25Kaw. I understand the reasoning behind engaging the blades at about half throttle(it makes sense), but in the Ferris owner's manual it clearly states to engage the blades at full throttle.

    Any body have any idea why they would want you to do that?:confused:
