    Yes,...you have to haveenough r's to substantially power it, so there isn't too much "jump" from te shock. We have always engaged ours at around 1/3 to 1/2 throttle, and vary it when running doubles. The key is how to shut it DOWN to save the clutch life, because THIS is where the vast majority of the wear occurs. The idea is to lower the r's and let the blades slow all the way before disengaging the PTO. There is much less friction and drag on the disk then, and therefore, does not wear on the air gap. This was told to me by a tech at Warner.

    Like Runner said.

    Engage the PTO at the lowest rpm you can without stalling.

    Disengage at idle speed when possible.

    I usually engage from 1/3 to 1/2 throttle. My 31 hp Briggs will easily engage at idle if that's what I want and the 27 Kohler will slightly above an idle.

    I have the exact same mower and it does the same ****! Check the spring tension under the deck get it real tight and engage the blades at atleast half throttle! I kept throwing belts too. When you engage the pto look at the belt while you have the cover off and see if the belt flexes. If it flexes its either not enough tension or not enough throttle. Hope this helps. It can be very aggrivating:dizzy:

    Does the manual recommend a throttle setting for engaging the PTO? Usually, the people that build the mowers, figure these things out at the factory during testing, and that is how they know what to put in the manuals for recommending operation and servicing.

    dealers always told me to engage at full throttle but cant see that being good for them. i usually do it at 1/2 throttle

    I've never heard that on a brand I have owned. What does the manual say?
