PTO Engagement

[Gregs JD1023]

I'm looking for some advice. I have a new JD1023E I bought in the fall of last year. It has a FEL & 54" Mid autoconnect deck. My question is in regards to the PTO engagement speed. Should I always lower the engine rpm to above idle (say around 1500-1800) before I ingage the attachments? I'm thinking of the stress load on the pto, drive system from a complete stop of the impliment. Also, what about pto speed. What speed should I run the mower deck? There is no info in the manual on pto speed. If I run at the the indicated 2100 mid pto rpm the engine runs at 3200 rpm. Since this is my first diesel I feel I'm running at to high an rpm for mowing. Any advice will be appreciated. Thanks.

The engine is designed to handle the rpm's. But I run at the rpm that sounds right to me. Sometimes that is less than wide open throttle, depending on the operation at the time.
So my suggestion would be go at the speed that feels good to you.
Both the engine and the clutch should take the heat, so to speak. Some feel better about engaging the PTO at lower throttle. If that feels better, then do that too.

Yes! Always lower the engine speed at least part way before engaging the PTO. In general with tractor operation, common sense about not putting too much stress on parts can go a long way towards reliability. So kudos to you, sir!

As for PTO speed, I would recommend to run at the lowest rpm that you can - provided you still get a high-quality cut, traveling at the ground speed you desire, without lugging the engine or trans at all. Doesn't have to be all the way up, but see what works for your application. If you get into rough cutting, you may indeed find you need 3000+ rpm. And if so, don't worry about the engine one bit. Engine are actually happier running at high speed and part load, vs. lower speed and full load.

Happy tractoring

This is what YOUR manual says (answers to your questions are in RED BOLDED font):

NOTE: PTO operation for this machine is not intended to be used when the operator is off the seat. The safety interlock system will stop the engine and all implements if the PTO is operating and the operator leaves the seat.
Engaging the PTO

1. Sit on operatorç—´ seat.
2. Lock the park brake.
3. Move the 2-speed range lever to the N position.
NOTE: The starter will not crank if the PTO/RIO switch knob is in any engaged/on position.
If the operator leaves the seat with the engine running and the PTO engaged, the safety interlock system will stop the engine and all implements.
4. Start the engine.
5. Set engine speed to 1500 rpm or less.

6. Move the PTO control lever (A) to desired operating position.
Position (B) - Mid PTO only.
Position (C) - Mid and Rear PTO
Position (D) - Rear PTO only.
7. Pull PTO/RIO switch knob up to the engaged/on position.
8. Adjust the hand throttle lever forward to the desired speed for the implement used.
NOTE: The tachometer PTO marker indicates a PTO speed at an engine speed of 3200 rpm.
Mid PTO speed will be 2100 rpm and rear PTO speed will be 540 rpm.
If PTO shuts off during use, turn off engine and push down to turn off PTO/RIO switch. Lock park brake. Allow engine to cool. Check coolant level and add coolant if necessary. Clean debris away from radiator cooling fins. Sit on seat, and start engine. Pull PTO/RIO switch up to the on position. If PTO still does not engage, see your local John Deere Dealer for service.
Disengaging the PTO

1. Adjust engine rpm to low idle.
2. Push PTO/RIO switch knob down to the disengaged/off position.

Your engine is built to run at PTO speed and mowers are most efficient at those speeds.
Do read your manual for break in info, if any...

Hey thanks everyone for the input & thanks to Roy for the manual info. I usually read manuals from cover to cover but I guess the PTO speed suggestions didn't sink in.:ashamed: As far as running speed for the mower I guess I'll use the play around and see what works method.

I am not sure about yuour Deere, but mine have PTO brakes to stop the PTO shaft when disengaging the PTO. Therefore I slow the RPMs before shutting the PTO off.

I also engage the PTO only at low RPMs.

Same here...about 1000 RPM to engage or disengage...
