What about some kind of overrun clutch like guys use on the 8N and 9N tractors? Wouldn't that provide some kind of cushion until the implement got up to speed?
That wouldnt help any as it slips in the opposite direction allowing the equipment to remain turning when the PTO stops. Its like a ratchet set on tighten in the direction that the PTO turns.

I'm not familar with your mower or tractor , but something ain't right . Flail mower , rotary with two big hinged blades , new , used ,how big ? It should stall tractor before it breaks anything . Just trying to help .
I'm not sure about that the way its being described engaging it sounds like its basically performing the equivalent of a clutch dump instead in a in a truck where you just dump the clutch and hope for the best instead of a modulated clutch release. This mower probably has a fair amount of rotating mass. Its basically like taking a medium duty truck loading it up to its GVWR and dumping the clutch with descent RPMs on the motor. i've seen everything from twisted Prop shafts, Transmission that have ripped the mounting bosses out of them and differentials spun around the axle shafts 15-20 degrees. normally these trucks have no problem hauling around a heavy load but do something they really were not intended to do and stuff breaks.

Kiotirx What are you using for a Shear Bolt, stainless steel or a grade 8 bolt? I would definitely put a slip clutch on it if Kioti has no way to adjust the modulation of the clutch. Normally the shear pins should give way before the gearbox although under these circumstances maybe not

Engage it at a idle or as low of a rpm you can with without stalling the motor.

You should also check the length of the PTO shaft to be sure it is not too long and to be sure it is not too short.

many thanks for all the answers.
I have checked the way it engages the pto and that electric-hydraulic. The electric switch engages a hydraulic pump and the oil forces the pto clutch to grab into the engine.
A mecanic told me that you can lower the speed of the hydraulic oil so it will go slower to work. anybody experience with that?
Also can you simply slower the idle rpm or is it electronic?
thanks

I have no experience with it, but my friends Case 110 must have a similar system, it brings the PTO up slowly. I do what others have suggested, I only engage the PTO at an idle and I've never had an issue with my snowblower. It does make the auto setting on the PTO a little useless, but this is the reason I've never been comfortable enough to use it in the auto setting (other in the summer testing it out a couple times).
