Adding PTO to a 9000 series Deere

Does anyone have first hand knowledge of this? I am only asking as I was thinking that you can add it all from the rear of the tractor without splitting it or tearing it all down. I found a tractor I am kinda interested in but it doesn't have PTO and I need PTO only for the grain cart.
THANKS!

Those 9000's have a very high flow 30+gpm and 2250psi hydraulic system.
If plumbed in with the power beyond supply and "hydraulic motor" return fittings. There maybe enough capacity if the proper torque/rpm/gpm/psi motor is chosen for the graincart.

You do not have to split the tractor. It is easier if the tractor does not already have a 3 point hitch on it. The parts are heavy. What you do is first remove the cab right side glass to gain access behind the control console. Then you assemble the pto mechanical parts and install. It is mechanically actuated. You also have to go into the computer and tell the tractor there is a pto on it. Then you remove the plate on the back side of the transmission and basically assemble a stub shaft that comes out under the cab. Next you install the clutch assembly under the step behind the cab. This area is called the gudgeon. Then you use a special tool to check alignment with the clutch assembly with the output shaft you put in on the back side of the transmission. After the two are aligned correctly you install the driveline from the transmission output shaft to the clutch assembly. This is a good time to install the hydraulic hoses. The pto clutch is mechanically engaged but it uses hydraulic pressure to engage and hold the clutch pack. Also you install and adjust the clutch control cable from the handle in the cab to the clutch. Then you install the pto gear box. Then you install hydraulic lines to the gearbox. Then you install the driveshaft from the clutch to the gearbox. Then you grease and install shields and safety decals. I can do one in two days by myself at the dealership. First one probably would take four days. Especially without having the special tools. I have done one without the tools. The pto comes in a kit form. The hardware is in a big bag and you have to pay attention what hardware goes where. If your dealer wants to do it let them. A John Deere dealer can print off the assembly instructions for you and for your transmission type. It probably would make more sense than what you've just read. I use a forklift and boom to install and lift the drop box and clutch. Good luck and have fun.

It is HIGHLY unlikely that the hydraulics will operate the grain cart drive properly, I wouldn't waste my money. If the grain cart you are using has a 16" or 18" auger the power draw is quite high (80hp or higher) the hydraulic system will never be adequate. Stick with a pto drive on your 9000 series.

Depends on the unload speed he wants. Even if 2HP is the max hydraulic motor that can be operated. Sized properly it will have all the torque required but run at 1/4 of the normal 1000rpms.
How much does he want to pay?

BuickandDeere, Seems that if Kevin has a 9000 series Deere and a large grain cart that maybe he wants to get the job done. If you underspeed a grain auger you severly limit the volumn of grain it can handle. Once the auger flighting gets full the torque required to turn the auger increases dramatically. Augers and auger drives have been twisted off due to low rpm and high torque. I had an employee decided that he would spare wear and tear on a 4840, he thought that running at low rpm would "save" the tractor and grain cart, the auger flighting ran full and stalled the tractor. what a mess trying ro get the auger turning again. Wasn't long after that the shaft out of the gear box twisted off. Your suggestion is like suggestion that one put a 10hp honda in a pickup to "save" money. Yes it could be geared to go down the road, but would you want to drive it?

Hydraulic carts are not very good,,We looked into one for our Brent 750 cart and went with a pto on our 8970, I think it was the better choice.. one of the main resons for a cart is to speed up the harvest, the PTO systems are "much" faster..

Thanks for the reply, that was excatly what I was looking for.

Also, to the hydraulic idea, at first I thought it sounded silly, then I kinda liked the idea, cause for about $1500 buys a nice hydraulic motor. Problem is with a 44 gallon per minute pump @ 2750psi (even assuming I can get all of it to the cart motor), I checked various displacements of the pump, and can't get more than 100hp no matter the size of the pump. And that was at 250-300 rpm range. Near as I can tell I really need about 80gpm to run the cart. I could run it slower, but I am worried about the torque twisting the shaft and also don't want a 15 minute unload time on a 950 bu cart

We have a Demco 950 cart with a hydraulic drive that we pull with a 9120. We tee"ed the hyd. motor lines to 2 scvs. It unloads faster that our old E Z trail cart. Can fill a 750 bu. truck in 5 min. Not as fast as we would like but we can live with it better that the $10,000 pto.

Here's even more flow than a set doubled scv valves. So many people have no idea that scv's flow only a fraction of the tractor's hydraulic capacity.
That's why the Power Beyond and Hydraulic Motor options exist but seem to a secret known to only a few. The data is all in the parts manual.

Problem wasn't low rpms. It was letting the auger stop which lets the grain fall-back and set/jam. No surprise the gearbox let go shortly after somebody yanked the pto clutch into engagement.
Hydraulics allow a smooth and gentle easing into the load. And a fixed max torque which will stall the motor before components are damaged.

I AM GLAD YOU HAVE ALL THE ANSWERS!

Hi,
Did you add the hydraulic drive or did it come from DEMCO that way?
Thanks
Kevin

30-40HP on a short buggy auger is no slouch.
35pgp X 2250psi/1714 X 85% eff = 39HP on a hydraulic motor.
This isn't a 100ft long 16" elevator auger filling a storage bin.

Kevin:
Sorry it took so long to reply, been away from the computer. We ordered our demco cart with the hyd. drive. Last fall was the first season. It was to slow with 1 scv and we didn"t want to take time to put power beyond on the tractor in the middle of harvest. We wanted to try the 2 scv"s to see if the extra oil flow would make a difference before we ordered the power beyond. Demco used 1" hoses to the motor but crimped 3/4" fittings on them. I think if we would replace the 3/4" with 1" it would help.
