Isn't there a rubber-booted plunger for the seat safety switch under your seat? I don't know your model at all, but JD's design standard is to allow you to pull up on that plunger to allow the PTO to be engaged while you are off the tractor. I have also heard that some models simply require you to engage the PTO while you are off of the seat to run it that way (meaning if you engage the PTO while on the seat and climb off, it won't run)

This came from Deere's online manual for the 4720:
Using Rear PTO (Operator off Seat)
NOTE: The rear PTO can be engaged with the operator off the seat. The Safety Interlock System will stop the engine and all implements if the mid-PTO is engaged and the operator gets off the seat.
Engaging Rear PTO
1. Sit on operator's seat.
2. Move transmission to neutral position:
• PowrReverser: Depress clutch pedal completely and move the transmission gear and range shift levers to the N (neutral) position. Move the reverser lever to the N (neutral) position.
• eHydro: Move the range
3. Lock park brake.
MX32728
Picture Note: All controls shown may not be installed on your machine.
4. Push the rear (A) and mid (B) PTO knobs to the disengaged/off position.
NOTE: The starter will not crank if the rear PTO knob is pulled to the engaged/on position.
5. Start the engine and adjust speed to 1500 rpm.
6. Get off the operator's seat.
7. Pull the rear PTO knob (A) to the engaged/on position to engage the PTO.
• The engine should continue to run.
MX32742
• The instrument panel PTO engaged light (C) will illuminate when the rear PTO is engaged.
8. Adjust the hand throttle lever forward to the desired speed for implement used.
NOTE: The tachometer indicates a standard 540 PTO (D) at engine speed of 2400 rpm.
Disengaging Rear PTO
1. Adjust engine rpm to 950 (low idle) or below.
2. Push the rear PTO knob (A) to the disengaged/off position to disengage the rear PTO.
• The instrument panel PTO engaged light (C) will go out when the rear PTO is disengaged.
There are also pictures...time to read your manual a bit closer, friend...

Why are people so rude?
Roy,
I have read the manual, but I have not practically implemented every operation in the manual. With that being said, I did pull my manual. It appears that the key is step 6: Get off the operator's seat. then engage the PTO (step 7). I was engaging the PTO while on the seat. It seems logical, I will have to mess with it a tad more.
I will figure it out. I just figured somebody could save me the time, I am ready to fire up this chipper!

"Why are people so rude? "
If you're referring to my post...I do apologize. My responses do tend to be direct and to the point.
However, it is very important for anyone buying a tractor or other equipment to have a thorough understanding of the machinery. The best place to find this information is in the equipment manual...

ddivinia, I believe you read something in Roy's post that wasn't there. I didn't see his post as rude in the least. He DID point out that all you needed to do was open your manual. Now, if you felt a little embarassed that the solution was that simple, it does not mean that Roy was rude.
Think of your Owner's Manual as a reference book instead of a novel. It's not likely you'll remember everything from a single reading, but when a question comes up, it is the best place to start researching.

I took offense from on these grounds, maybe I was having a bad morning:
Pictures do not explain the procedure.
I have read my manual, and do look up things from time to time, but I figured why not type the question right in here?
All good - I am about ready to fire this chipper up. I tested out the PTO while off the tractor this morning while I was out mowing.
Thanks,
D.

I for one like the way you answer a question. It is direst and to the point. Not like some that give you a lot of hogwash because they don't know what they are talking about. You are one of the people I like to pay attention to what you say

"Pictures do not explain the procedure"
No, but they are used to identify the locations on the controls. I'd of posted them, but expected you to look in your manual.
We can give generic advice and opinions on this web site. Always take what you read here with a grain of salt.None of what you read here will replace usage of your manual. It's possible you may get bad advice, so keep that manual handy.
I suggest in the future you not read anything into any of my posts other then what is written. No harm done with me, as I have the hide of an elephant. Other folks here may have taken offense to your comment about rudeness.
