This works out at around €200 by my calculations.

For the difference that's in it after sterling, vat and delivery, if you're getting a genuine original WALTERSCHEID shaft, with proper bellows type guard and slip clutch, across the counter for 300, then it's worth the difference IMO.

not cheaper but you'd never be wanting for parts again :P

It would be a better buy than paying 300 for a shaft.

w bad would it be to use a normal pto shaft on these? I have one long enough from a dung spreader? Would it make **** of the haybob?

Pretty sure they are just a normal shaft, no wide angle joints or slipclutches or even shear bolts in them. The only special part is the shaft cover. I wouldn't recommend using one without the correct cover, apart from the obvious safety issue it will drive you nuts with grass wrapping around it.

They have a slip clutch on the tractor end of the shaft.

Machine end for the clutch! Or atleast that's the way any slip clutch I've ever seen works. And the pz we had here had the slip clutch inside the big long end of the guard that was jubile clipped onto the input shaft.

With the slip clutch at the machine end when too big a load comes on the machine it knocks out the drive as quick as possible. When it's up near the tractor the load has to go through every bit of the drive line before it will knock out.

Overrun clutch so, always on the tractor end if you turn it around it will turn in reverse and won't work.

Nope deffinitely a slip clutch! Same on a baler, slip clutch next to machine, wide angle at the tractor end!

And the only thing here with an over run is the mower and it's also on the machine end, it's actually on the second shaft, from the 90degree gear box to the bed just before the pulley for the conditioner belts

If you have a look on done deal there's a guy that sells Pto shafts. He does watersheid and a few other makes too that are around half the price. I bought a new wide angle drive for a beet harvester off him last year and saved a ball of money. I think he's in cork

On the PZ haybob they are on the tractor end.

We'll have to agree to disagree so! Had 2 of them here, one the last of the pz haybobs and the other a vicon 300 and both had there slip clutches on the machine, the vicon came brand new that way

On the machine to protect shocks/too much pressure going through the shaft

Same as a shear bolt? ?


Can't see how direction of rotation will effect it.....it's when it overcomes springs/they get weak/points get worm it slips afaik

PZ haybob which the thread is about have the clutch on the tractor end if you turn it around to have it on the machine end it won't work because it will be turning the opposite way, comprende.

Lads some of ye are getting mixed up between a slip clutch and an overrun.

Slip clutch can be put anywhere on the drive line. It's function is to stop the tractor driving the machine should something jam the machine, to avoid blowing the machine to bits. Similar to a shear bolt.

Tom, Sam is talking about an overrun which cannot be rotated the wrong direction, and you are talking about a slip clutch which can be rotated in either direction.

Overrun simply lets the machine slow down itself when you turn off the PTO. So that the PTO brake does not try and stop the machine.

Any hay bobs I've ever seen had an overrun on the tractor side. No slip clutch.

CJPM, you summed it up in a mouthful. Top marks. Haybob has an overrun on the tractor end. It is not a slip clutch.

I mentioned that it was an overrun clutch earlier but someone said it was the same as a slip clutch :rolleyes:
