Rotary Cutter Overrunning Clutch

[MROlson86]

I’ve got a 5’ rotary mower that I normally use an 8N to pull, I want to try my Mitsibishi 300D for the job. Should I install an overrunning attachment on the PTO? I use one for the 8N.

A quick Google search seems to indicate that your tractor does not have an integral overrunning clutch. Use the external one that you use on your 8n.
I'm not familiar with your tractor so could be wrong, someone will certainly correct me if so!

Your 300D has independent pto,therefore no overrunning clutch required. I strongly recommend you procure and carefully read the operators manual before operating the tractor.

We have an old Ford, that switch has been going out for decades

I like to run an ORC even on a tractor with an independent PTO but that's just me.

Everyone likes to save money,extend service life,save fuel and other benifits from tips and tricks. Do you mind sharing what the benefits are of running a ORC on tractors with live or independent pto?

First I prefer the PTO on the tractor to stop when I turn it off and not coast down with the cutter. Second its another weak link in the PTO drive line to fail before something expensive in the tractor gets damaged if happen to hit something that should not and not rely entirely on the slip clutch should for some reason it fails to work. Which has happened, even though it looked fine it was rusted tight even though stored inside a shed.

Like I said its mostly just me, as most will think it unnecessary or useless on live or independent PTOs.

An over running clutch on an independent PTO will save your internal PTO brake.
Some of them can be very expensive to replace.
It certainly will not hurt any of them.

I just rebuilt my overrunning clutch Wednesday on my Krone baler. The grease inside turned to dirt and the springs were in bad shape. Looks like previous owner used clay based grease and moisture got inside. Turned that CB grease into dirt.
$800 for a new one. Rebuilt it for $50 bucks.
