PTO Clutch?

[winesalot]

Just bought my first rotary mower. It is an older Massey Ferguson. It is missing the gearbox and Pto driveshaft. In doing my research on those two components I learned about Pto clutches that can be installed along with the driveshaft. I then saw something about the Kubotas having a built in clutch so these are not necessary. Any thoughts on this? My tractor is a L4701 that I bought new in 2017. Thanks in advance!

All pto operated machines need some type of overload protection on their drivelines/gearboxes. Protection can be in the form of a shear bolt/pin or functioning slip clutch. Built in clutch on tractors I think you might be referring to is an over-running clutch which allows implement pto shaft to spin after power is disengaged on implements such as rotary mowers that the spinning blade carrier has momentum from the flywheel affect of rotation causing implement pto shaft to spin after power is turned off. Over running clutch doesn't provide over load protection for implement gearbox or driveshafts.

Yea as @Tx Jim stated don't confuse a operational clutch with an overrunning clutch or a slip clutch.
Each one has a different job.

You ever get your engine in your excavator worked out?
