Does L4150 have built in PTO Overrun Clutch?

[MichKubota]

Does anyone know if the Kubota L4150 has a built in PTO Overrun Clutch?

Don't see anything in owners manual or work shop manual that talks about this feature. I thought all modern day tractors (including the L4150) would include a PTO Overrun Clutch.

With PTO engaged (engine off) I can not manually turn the L4150 PTO CW or CCW. Because I can not turn CW this indicate to me that tractor does not have overrun clutch on PTO. Just a little surprised.

On my L3650 I can turn the PTO CW without issue indicating it has a built in overrunning clutch.

No, the L4150 does not have an over running pto. It has a 2-stage clutch (pedal disengages wheels first, then the pto) and a 2-speed pto gearbox with neutral. Over running coupling isn't needed if the pto can be disengaged.
Over running couplers are available as add-ons - about $50 - like the one from Steiner (see pic). The L3650 was available with either a single clutch or dual clutch. If your L3650 has the single, then something like this might have been added by the dealer as a safety item?

Thanks rbargeron for info on L4150. My L4150 has single stage clutch, but "No PTO Overrun Clutch" from what I can tell. This tractor has "Hydraulic Shuttle" which does allow shifting shuttle to neutral and disengage PTO from driving rear wheels.

I just rebuilt GST trans on L3650 last summer. It has single stage clutch but includes PTO overrun clutch as standard equipment. The pic from WSM shows the mechanism used on L3650.

Many years ago sold a Ford 8N and gave away the external PTO overrun clutch with it. Never thought it would be needed again.



Thanks again.
