Okay for the last time I'll try to explain this it must be my fault. Does your tractor jump off the ground or sound like the Driveline is going to snap in half because it goes instant on?? That's the problem more than just shutting it off please try to understand your overrun clutch is not going to allow a slow ramp up of power is that enough to understand what I'm complaining about even the rep looked at it he could not understand why this was occurring. Even at the lowest RPM with the tractor idling if you engage the 8 ft bush hog dual spindle the tractor will either stall or you'll have an instant shaking like something's going to snap never mind with the snow blower does it's even worse 9 ft snowblower. There's no slow ramp up of power it's on or off it's ridiculous so you have to turn the RPMs up a little bit and at that point you're risking snapping a Driveline or a sheer bolt luckily the slip drive on the bush hog gives not so good on the snowblower you got to carry a lot of extra sheer bolts with you from just engaging the machine LOL they're looking into. By the way there's two workmasters on the Dealer's lot that do it even worse I just don't understand what they were thinking with the design like this and I was told they can bypass the pressure and allow it to go on slow it's simply a safety feature that's way overdone someone must have chopped their leg off on a workmaster ridiculous take care
They probably did that to mitigate pto brake clutch failure and far as an abrupt start of any implement, the addition of an adjustable multi plate slip clutch in the driveline will eliminate that issue entirely.
Most of my quality implements including my disc mower (which happens to be a New Holland) as well as my new Kubota BV round bailer have them factory installed and so does my new pto driven stump grinder.
My Land pride 9 foot brush hog didn't come with one and neither did my 15 foot bat wing fold up shredder but, I added them anyway.
A slip clutch in the driveline as well as an over running coupler will totally eliminate and and all driveline shock when starting up any implement or stopping them when any implement will drive the disengaged pto stub. The pto will come to an immediate stop and not rotate at all and that totally eliminates pto brake wear, which is something I needed to do with my large frame Kubota's as the Kubota pto brakes are marginal at best and replacement requires splitting the tractors, which is a very involved process and if done by a dealer will be extremely expensive.
Tractor Supply sells them, I believe the Weasler brand but they can be had cheaper on line. Never replaced a shear bolt on any implement I own other than my own stupidity like sucking up a paving brick in my snowblower and locking the impeller.
My final comment is, quit whining and take care of the issue. I've laid out the plan in detail as to what to do. Up to you to remedy the issue. if you cannot do it yourself, have your dealer install a slip clutch. Far as the over running clutch on the pto stub, that is totally plug and play.
Do keep in mind that you will probably have to shorten the sliding halves on the driveline to compensate for the additional length of the slip clutch as well as the over running coupler and I presume you know how to do that. If not, have the dealer do that as well. he knows the procedure.
Have a nice day, I'm done here....
