John Deere 820

[jenkinsph]

Thanks to everyone for your help. I want to make sure I am doing the pto correctly. The pto handle is on the left side underneath the seat clutch fully engaged lever should move forward and stay. Release clutch and pto should be moving. Is this correct?

Correct. With the engine stopped see if the lever will move to engage, if it does with the engine off but not with it running the likely culprit is the clutch adjustment or it is worn out. This assumes the rod itself is not stuck, are you getting any movement at all? It may free up on it's own if you are lucky after some use and driving, that should help circulate the oil over everything in the case.

The pto handle will not move forward. It will move toward the left wheel. I tried it both ways engine running and off. I will drive it around for a couple of days and see what happens.

Something else you can try with engine off and in 8th gear would be to have someone rock the tractor slowly using the rear tires while you try to move the lever.

The lever should not be moving outwards in the direction of the wheel at all. If it does it will possibly bend and break off. I would try to spray some Liquid Wrench or PB blaster on the shaft the lever is attached to that enters the housing. This may have rusted or siezed on you. After spraying this tap it very lightly with a hammer to help free it up. The idea is to vibrate the shaft a little not beat on it.

Is your grandfather or whoever gave it to you able to provide any information on the pto problem?

I will give that a try tomorrow. My uncle (which is 99 years old) said the last time he used it was with a bushhog. It said he had finished with one field and went over to the next field to continue. At this time we went to engage the pto and it would not engage. Everything else it working fine on the tractor I drove it around for about and hour today with no problems.

I guess the next step if this doesn't work tomorrow is to break the tractor apart and see what it looks like on the inside. Has anyone done this before?

I bought mine in 1997 with a bad clutch in weathered condition, first thing I did was put in a new clutch and water pump. Only thing wrong with the clutch was the inside spline in the center was stripped. Probable cause was someone trying to pull it to start and popped the clutch. The linings were like new.

You can split this tractor if you have some decent jacks and a way to roll the separate sections apart. I found it easier to block the front section in place and move the rear section away. I would get the service manual and look through it first.

Does the rear shaft turn free or is it stuck?

 

[cannedman]

I will check the rear shaft today and see if it will turn. The manual has been shipped so I should have it in a couple of days.


Thanks and have a great day.

The shaft turns freely. Putting the tractor in 8th gear and rocking the it back and forth did not work. The handle just will not move.

Here is a drawing showing the linkage from JD parts.

 

[cannedman]

From what I can see from the drawing I am trying to move the wrong level. There is a handle underneath the seat that will move toward the wheel and then there is a littlie handle ahead of it and from the drawing that is what I should be moving. If that is the case that handle will move.

Notice the two levers along the side of the housing the one up close to the clutch pedal if present is the mid pto lever, the one that is towards the rear is the rear pto lever.

 

[cannedman]

Thanks Steve. I have the number 2 handle. If I move that handle toward the rear that handle will touch the one I was trying to move. The handle I was trying to move is much larger.

The pto handle will cause the pto shaft to move if I move it forward. However the shaft does not move very fast it rotates very slow.

Try adjusting the pedal play on the clutch, according to the manual it should have 1 inch of play and not less than 1/2 inch.

 

[cannedman]

My manual came in today and I tried the clutch adjustments. It did not help any. I guess the next step is to break the tractor down and check the pto clutch. Does anyone have any other suggestions other than the break down?

 

[jenkinsph]

I would look into buying the parts or having the money set aside first if it may be an issue. I would also check on this at NAPA and do some scouting around to get the best price. I wouldn't split the tractor until I either had the parts or had them located, nothing worse than having your tractor opened up for a long interval.


I don't have a service manual, if this is what you purchased then did it have any info about a pto clutch adjustment?

 

[cannedman]

The manual I got is a shop manual. I would not even think of trying to break the tractor apart. I wouldn't know what I was looking at of what I should be looking for. I will have to save my money and have someone that knows what they are doing to do the job.

I talked to the John Deere dealer and they want $3000.00 to fix it. I thought that was kind of steep.

 

[jenkinsph]

Well at least you have it up and operating, I would still change the hydraulic fluid if you haven't done so. Then use it for boxblade work and other tasks that do not require the pto in the meantime. I say this because I would wan't to know if everything else is in good shape before spending the money on the repairs. My point in all of this is you need to figure out what the entire tractor needs to fix up and what the costs will be. Then start comparing and get an idea of what is practical and feasible to do.

 

[cannedman]

I have changed the fluid and the filter. I will use and see what happens. I want to thank you for all of your help and guidence.

Have a great Christmas and a Happy New Year.

I found the problem on why the pto does not work. The groove pin that goes into the arm is broken. Does anyone know how to get the pin out? I have tried plyers and vise grips but no luck getting it out.

TIA

 

[jenkinsph]

Not sure which arm you are referring to, can you be more specific?

If what you are talking about is a roll pin, I usually drive these out with a flat round punch of the proper diameter to match the hole. If it is mushroomed you may need to saw this flush with the surface first then use the punch.

 

[cannedman]

This is the pto lever that engages the pto. The groove pin that goes through the arm is broken. The pto lever just slides around on the shaft. I removed the rockshaft housing and I can see the pin. When I try pull it out it won't move.
