I just got my PTO powered chipper and I am wondering how can I keep the PTO running without me being on the seat. I have John Deere 4720.

Thanks,
D.

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.

Good and complete response to the question. You put a lot of time and effort into that post, that will likely help a lot of people in the future on this forum, that have the same question, and put PTO Safety Bypass into the search engine.
Very well done. When I read it, I didn't think you were being 'rude' by the use of 'friend' in your sentence. It was obvious by the question, and probably embarrassing to actually realize the answer was there all along, and 'not reading' was what led to the question. I thought this was an excellent response. Maybe a big ol /forums/images/graemlins/grin.gif at the end would have helped, but then you were probably tired of spending so much time already answering the one post.
This is something we all can learn from, IMO. /forums/images/graemlins/wink.gif /forums/images/graemlins/tongue.gif /forums/images/graemlins/grin.gif

I believe the part that's 'confusing' is getting off the seat FIRST...before engaging the PTO. That's what got me hung up. I kept thinking I could have everything in neutral, brake on and then get off the seat. You have to get off the seat first. It would be more useful if you could engage while in the seat and then get off without killing it. It's an issue (like I said in my other thread) when mowing. You can't leave the PTO engaged even if everything is neutral and brake on. Sort of defeats the purpose of having the PTO run while off the seat...at least when it comes to mowing, in that specific circumstance.

Sites like this and truck forums (for example) crack me up. No offense to anyone and I'm not pointing fingers (really), but these sites tend to have resident experts that know the answer to everything. Not necessarily related to this thread...but it's an observation I've made over time when looking at sites like this. Someone gets a truck, tractor or whatever and operates it for a few years and the next thing you know, a newbie comes along and gets whacked for asking stupid questions...LOL /forums/images/graemlins/grin.gif That's why I tend to lay low unless I'm lazy about looking something up or really can't figure it out. These sites are a good resource, but sometimes people can be a little abbrasive or short. I make no claims of being the expert farmer, etc. My day job is telecommunications and I do think I qualify as an expert in that field after 15 years or so in the business and high praise from my customers and managment. So if you have a business phone system/voice mail/video conference system question, fire away!...LOL Unless I have real experience with an issue someone is having here, I usually keep my lips zipped...unless I know where in the manual to point someone if it's a simple "it's in the manual" response that's appropriate. One thing people have to keep in mind here (on the internet) is that it's difficult to determine someone's mood or state of mind since there's no way to hear a person's tone of voice or see facial expressions. It's easy to get the wrong impression sometimes. I think that's what everyone should remember.

By the way (I might get shot for this), think about it. We're talking tractors here...mainly compact utility tractors. Do you think the vast number of real experts out there are watching this forum?...the people running combines and other large and extremely complex equipment all day long? No. They're out farming or doing whatever it is they do for a living with their tractor. Most of us here are part-timers on the tractors we own and simply love operating them and sharing our experiences. I don't know any farmers (although there may be some here) that follow forums on the net and spend a lot of time here. Like I said, they're mostly out working and couldn't care less about a tractor web site. That's just the truth of the matter if you think about it. I follow a truck forum (pickups) too and the same sort of thing goes on over there too. People picking on each other over petty things about who knows the most about trucks or who can find what in the manual better than someone else. If I didn't have the proper perspective on the issue of web forums, I'd go crazy. But since I do, I get a giggle now and then when people get all worked up over things people type on the internet. Honestly, I'll never meet any of you and I doubt most of you will meet anyone on here either. Don't stuff so personally /forums/images/graemlins/wink.gif But then again, think about impressions you might leave with what you type (unless you add the proper amount of smileys so people know you're friendly or joking).

I don't think this is what happened here with this thread...I think the person got the wrong impression based on simple text with no smileys, etc. This whole issue with this thread going the wrong way just reminded me of how things happen on forums. In general, I think what I've said above is true...if you stop and think about it. We see it all the time. I learned to not get worked up about what people type. It's just text and I'll never meet the goofballs anyway /forums/images/graemlins/wink.gif

Have a great day folks /forums/images/graemlins/smile.gif

P.S. Before anyone gets the wrong impression /forums/images/graemlins/wink.gif ...I know for a fact there are some VERY experienced people on here based on some of the responses to various threads I've read. I'm just saying, the majority of us here are simple tractor lovers that like to spend time on the machine and share experiences and answer questions when possible. I think we can all agree that the huge majority of people who know tractors like the back of their hand don't visit online discussion forums. Just like the vast majoirty of pickup truck owners don't. The membership of one truck forum I follow is several thousand. Ford alone sells around 1 million F series trucks every year...but you don't see millions of F series members on the forum. That's what I mean.

Who died and left you to be the resident psychic? I, for one, am a full-time rancher and yet still have time to participate in this forum.
Speak for yourself.

Well...I think this thread has outlived it's usefulness..time to close it...

Cheyenne, he did say "vast number". Of course, we've got some real farmers and ranchers, even some tractor mechanics or technicians, but I don't imagine we even have the "vast" majority of compact tractor owners (they have sold more than 21k compact tractors, haven't they?). /forums/images/graemlins/wink.gif /forums/images/graemlins/laugh.gif

At any rate, I agree with Roy and think it's time to just close this thread, so I'll do that. /forums/images/graemlins/laugh.gif
