How does one use a PTO chipper with an electric PTO clutch?

Now that looks like a chipper should look like, :drink:

The JD 6200 is little underpowered to run it at max capacity. The guy that had it used a 5000 series. I have a sneaking suspician, he didn't have much luck.

When I get a few old projects out of the way, I would like to put an auto-feed system on it. Stop hyd infeed when RPMS drop. One electric valve and a tach with alarm output should do it.

Engaging the PTO at idle means the clutch slips as little as possible and should make it last a long time.

...and stopping the PTO at idle.

Both of the JD4300 rental tractors I had had broken PTO brakes. The PTO brake has several less clutch discs versus the
clutch that engaged the PTO. I fixed the first one, but deleted the brake on the second unit.

The PTO brakes on both tractors were likely broken by renters who turned off the electric PTO switch at speed while
operating the large rotary mower. A chipper would have been worse.

I have no choice other than to engage at 3/4 or so RPM. But I could try and slow it before disengaging, to save the brake, as I usually disengage at full RPM. The chipper does have an over-running mechanism.

I have always been able to turn my PTO by hand, when the tractor is off. I wonder if that changes with it running.

Deere has a cool setup on the 4300, and probably their other newer tractors with electric-engaged PTO: with the tractor off, the PTO can be turned about 30-45-degrees. I assume this is to help getting the drive shaft aligned correctly when attaching it. Beyond that, it does not turn.

If a tractor has a PTO shifter, allowing for a neutral position, that would be a plus if it can be shifted with tractor ON.

My Kubota L4060 does the same. Can get a partial turn before it stops.

Since my LS is a manual transmission, I have a clutch to go along with the electric PTO switch. I start my bushhog with the clutch fully engaged, then pop the electric PTO button and then slowly release the clutch. The PTO engages prior to the transmission engagement so it is easy to feather it in. Some HST tractors also have a clutch that I suspect is useful for that purpose.

Might want it to stop feed and back up too. Helps return to rpm as no drag on the chipper knife face, Tech Tips

Do factory setups do that? It would make my project much more difficult and expensive. If it had electric valves it wouldn't be that hard, but it doesn't.
