Hi:
I bought my 2310 in March and haven't seen it sense and won't see it until June so please bear with me.
I'm planning on buying a brush cutter (5 ft I think) and thought that the PTO would drive the cutter with the Power shift in neutral. If that is the case and the PTO will continue to drive the cutter as long as the clutch is engaged I don't see what an over run clutch would do. It would seem that you could shift into neutral, brake and shift to reverse all with the cutter still spinning. From my old 9N days I understand how a cutter can "push" the tractor but I thought the power shift would get you away from that.
Is this not the case??
Thanks
Terry

Install an overrun clutch and play it safe just in case you get busy with something else and forget to shift to neutral. Ernie supplied one with mine, 1820D with Power Shift, and I never questioned it. The peace of mind and ease of overall operations is worth it.

Shifting the Powershift to neutral is about the same as shifting the PTO to its neutral, when you are in trouble.

Apparently in real-world operating conditions shifting the PTO isn't very effective to avoid crashing into something. So I don't think finding neutral on the Powershift would work any better.

It seems that having an overrunning clutch would still be better, even though you have the "emergency stop" option of a shift to neutral. Slowing down by reducing the throttle will still make the mower push the tractor forward, since the hydraulic clutch would be engaged. The other nice thing about the clutch is it lets the mower stay free-spinning if you need to throttle back to precisely back into something with the mower up, then have it at speed when you lower the cutter into the foliage.

Shifting into neutral will become a pain in the rear after an hour of mowing.
Also in an emergency the O/R clutch will work many xx faster than your hand shifting to neutral.
Just buy the clutch and have a piece of mind:D
Its cheap insurance as the others have said.

Override clutches are cheap and quick to install, my tractor has it built in but on the old tractors they saved my butt.

You have to use the clutch to shift ranges, so without the overrun clutch, you have to stop the blades to do that. For $68, just install the clutch. Make sure the drive shaft is not too long to accomodate the extra 6" or so of shaft length. Mine was ok without shortening the shaft, but I have heard of folks punching out their PTO tractor shaft by having the BH shaft too long. Prior to attaching it, just raise and lower the bushhog to see where the shortest point is and then make sure your BH drive shaft will telescope in enough to attach to the tractor at that point. If so then no problem

Thanks to all for the reply's. From a safety stand point having the over run clutch seems worth the $70 or so it will cost. Because I'm not running it yet I hadn't thought about stopping short in an emergency. If I get any additional benefits when maneuvering so much the better.
Thanks again.
Terry
