gut says 'better safe, than sorry' !
look at 'online parts' or WSM, see how the PTO is connected and what the cost of parts will be when you 'backfeed' the cutter's energy into the tractor.
A small 'cutter' shouldn't be a problem but a 7 footer could be.
Hopefully those with the SAME tractor you have will reply soon.

Yes it's a 5ft with a slip clutch. That said L2501 is a small tractor.
Just looking for some guidance.
Is it worth it??

Your tractor (probably) already has an over run clutch built into it. What happens when you push the clutch in? Does the tractor come to a stop or still want to move like the transmission is being driven? I assume you come to a stop and the cutter is still coasting down but spinning. That proves there is an over run clutch built into the tractor.

If you maintain and adjust the slip clutch you already have, then you should be fine.

Thanks that's the information I wanted.
I love all this wisdom on this forum for a Ole rookie

The L01 series has an over run system built into it as it uses a dog clutch to engage the PTO.

curious, found this... so Wt, the #120s are the 'cam clutch', allow power from engine to implement but not the other way due to the 'ramp and notch' ??
Used in various forms on many Kubota models including my L3901HST. Does not have the ramps but it is one way.

The old N-Fords had PTO’s that were direct-drive and overrun clutch’s were a safety-requirement …unless you wanted the shredder to push you into a tree …or whatever. (the PTO was connected to the final-drive…and a shredder would drive the tractor regardless of whether the clutch was pushed “in” or not… :oops: … so you definitely wanted an overrunning clutch!
(It might be an easy thing to check: With the tractor NOT running…and the PTO engaged…. see if you can twist the PTO-shaft clockwise by hand…. If so, then it will be free-wheeling (over-ridden).

The modern tractors usually have it built-in… the implement cannot usually drive/propel the tractor.

My Kubota’s Owner Manual recommends the PTO only be engaged and dis-engaged at “reduced throttle”.… presumably for safety as well as to avoid unnecessary PTO-clutch wear.
