Roller Mill pto shaft

[Bealy]

Currently renovating a superior sh15000 mill. The pto shaft missing and I'm not sure how heavy duty one I'd need and whether it'd need a slip clutch or I'd get away with just a shearbolt.
Any ideas?
Thanks

Mine came with a shearbolt, unanticipated shock loads better coped with like that and at least everything stops preventing more widespread damage.

Direct belt drive are they not? If so would have thought you might need an overrun clutch on the end to protect the tractor.

Yeah it is, only 400rpm too so it'll have some torque through it. Thought I'd get away without one as should be running at constant speed, I've never used one before though..
