I have just acquired a nice little TEA-20 and would like to attach a small loader that I have here. How do I tap in to the existing hydraulic system to power the loader? Im not concerned with great speed, just functionality. The 3-PH works fine, when the pto is engaged. Im just not sure how to take a feed from the internal pump and where to hook the return line. Thanks.

LIVE THANG, LIVE HYDRAULICS FOR THE FORD N AND FERGUSON TRACTORS. I now have a live hydraulics kit ready to install in about an hour or two. I am going to call it "LIVE THANG" in keeping with all the other stuff I have to offer on the Internet for owners of the 9N/2N/8N Ford tractors and Ferguson tractors with the original Ferguson system lift.

$450.00 is the price for the basic unit With the basic unit you will have the live three point hitch hydraulics and be able to raise and lower the three point hitch without the PTO turning or the clutch engaged. You can still use the PTO and the PTO pump will not be changed except for the fact that if it is running too the lift will respond about twice as fast as before the LIVE THANG was installed. No drilling or welding is required. THE THREE POINT LIFT IS STILL OPERATED WITH THE ORIGINAL TOUCH CONTROL HANDLE. NO ADDITIONAL CONTROLS ARE NEEDED TO OPERATE THE LIFT.
The unit consists of a low volume pump similar to the original pump capacity that is mounted to the engine by existing bolts and is belt driven. State whether you have a front mounted distributor engine or a side mounted distributor engine. The pump bracket has to be fabricated differently for the two.
It will take the average person about one or two hours to install and get it up and running. Nothing of the original equipment of the tractor or its appendages is changed. It is just an addition to existing points of attachments etc. No drilling or welding is required.

If you want a filter in the suction side of the system which I recommend but is not necessary add $60.00 to the basic price. Having a filter on the suction line will give the lift system a filter which we all know the Ferguson/Ford hydraulic system has been long lacking and needing. The addition of a filter and the plumbing for it would bring the price of the basic unit to $510.00

To add an additional two spool remote control valve less the mounting bracket and without any additional piping/plumbing will add an additional $200.00 to the basic unit price. A single spool valve is also available at about $125.00 additional if the two spool is not needed. I do not furnish the mounting for the remote control valves or the mounting bracket for the filter. You would have to fabricate and mount the control valve where you want it to go yourself. The plumbing and piping for the control valve/s would not be included either since it would be hard to figure what your needs would be and expensive too. I try to keep these kits at a minimum to be affordable to most people. The pressure hose that is included in the kit can be used to route the pressurized oil into the remote control valve if you should decide to use the spool type control valve for remote cylinders etc. such as on a loader.
Most of the original N loaders had only single acting hydraulic cylinders or one way cylinders which ever you want to call them. They had to be made this way because the N lift would only work one way by applying pressure to the cylinders when the touch control was moved up and the lift arms were tied down so that the oil had to go somewhere and in this instance it would go to the cylinders on the loader and raise the load. It is very hard to control the lift of the loader with this set up and you do not have a positive position control of the loader.

With the auxiliary remote control valve you would be able to use double acting or two way cylinders and be able to control the load by moving the valve to the center or neutral position and have the lift stay where it is and not drift up or down as it wants to do with the old N system of tying down the lift arms etc.

If you wanted to have a loader that had cylinders to raise and lower the load and also be able to control the bucket angle and dump the bucket then you would have to have a two spool valve. One to control the height and one to control the bucket.

Basic unit will give you live hydraulics for the 3 point hitch. The lift will operate when the clutch is depressed and the PTO is not turning. Or you can use it along with the PTO pump with the clutch engaged.

If more sophisticated models are requested I will give a price upon description of the valves and taps etc you want to operate such as remote cylinders etc.

Please state what year tractor the device will be used on and if it has the original generator or has been converted to an alternator and what size width belt it uses. Wide or narrow.

The older model engine block castings are different than the later model engine block castings. On the older blocks like in the 9N/2N and the 8Ns built before 1951 the oil filter mounting boss and the oil filler/breather openings are different than the 8N blocks. The earlier models have these two part closer to the front of the block by about 3 inches. this makes it necessary to have a different mounting bracket for each one. The Ferguson tractors with the Continental engines have a different mounting bracket for the pump than the Fords. The rest of the unit is the same.

Just send me a money order or a personal check to - Zane Sherman, 2824 Renfroe Road, Talladega Alabama, 35160 and I will be glad to get one on the way to you. I accept Paypal too. wzsherman@aol.com

Thanks, Zane Sherman

If you want to use a spool valve for a loader with a TE20 series tractor, you need to stop the lower lift links from going to the top or it will shut off the Pump. You need to tap into the Hydraulics of the tractor, usually into one of the plugs on the Pump Base right at the bottom below the seat. Depends on how old the tractor is as to how many tapping off points it has, may have up to four. Attach the feed for the spool valve to one of the tapping off points and then you need to return the oil from the valve to the hydraulic system, you can do this through the top setscrew that holds one of the Round Side Panels, you will need to make up a little adaption for doing this. Put the Tractor Control Lever to the top position and leave it there, to operate the loader all you do now is operate your Spool Valve. Don't forget to put the PTO in gear to use the Pump on the left side. Do not return the oil from the Spool Valve to the gearbox filler plug or you will drain all the oil from the hydraulics into the gearbox and it cant flow fast enough from the gearbox to the Hydraulics so you will starve the Pump of oil and you may find that the increased oil level in the gearbox will get out and run all over the clutch. Be careful when you screw anything into the Hydraulic Pump Base as it is only soft metal and will strip if you are heavy handed when tightening it up, make sure that you do have the correct thread on the adaptor you screw into the Pump. To stop the Lower Lift links from lifting all the way to the top, use a Trailer Pick-up hitch Tee bar if you can find one or use the 9 hole drawbar with some extra strong stays (like drawbar stays only heavier) attached to the long hinged pin underneath the top link attachment point on the tractor, do not attach them to the top link attachment point or you may bend something. If your loader doesn't have a Spool valve just take the oil from the Pump the same as before and use the tractor lever to lift and lower, no return line is necessary then. If you use this method, never leave the Hydraulic lever at the top of the quadrant, when you get to the height you need, move the lever forward until the loader starts to drop and then lift the lever slightly until the loader neither lifts not lowers and set the little lever stop to this position on the quadrant, all you have to do now is bring the lever back to this position each time, even without looking you will be able to do that.

I have one of the first type Ferguson tipping trailer (3 tons) from around 1948, the one where the front end of the trailer rests at the tractor top link via a special link. This trailer is tipped by means of the tractor's hydraulic, and a special rod is mounted between the top link and the drawbar which interconnects the lift arms, so that they cannot lift. If they were allowed to lift, they would cut off the hydraulic as soon as they reach their top position.

I believe there are four tap points from the hydraulic system, two at opposite corners of the bottom cover of the pump housing (hexagon plugs) and one at each side of the top cover, just in front of the driver's saddle (Unbrako plugs) (the latter ones may possibly be return plugs, though). Any single-acting cylinder may be connected to one of these points, and is to be manoeuvred by the lift handle.

You do not need any return connection; when you lower the lift handle, the oil will drain back through the same connection point. There is no possibility of power return unless you add an external valve block; the cylinder has to press the oil back by itself. Ferguson made two loaders for the TE-20 to be manoeuvred this way.

I plan on using an external spool valve to control my loader. I also have a 58' Dexta and installed a loader in this fashion. However there is a valve under the seat that has a fluid take-off point and I just leave it open to feed the spool valve on the loader, and the fluid returns back over the rear axle. I am hoping to use the TEA-20 system in the same way. Do you expect any problems?

Yes, I am afraid so. There is no fluid take-off point of that kind on the TE-A20, the only take-offs are the ones I mentioned, and they are connected directly to the lift cylinder. That is, the only place you can send oil to from the tractor's pump is to the lift cylinder and the take-offs - simultaneously. And as soon as the lift arms go up, the pump cuts off. And remember, the only way to control the oil to the take-offs is by the lift handle.

On the Dexta and the MF35, the oil take-off is connected directly to the pump, independently of the lift hydraulics. And their pumps run all the time, in order to supply the take-offs with oil in all situations. There is no such take-off on the TE-A20. And you probably cannot make one, because the pump and the lift are so tight coupled together mechanically that I believe it would be impossible to separate them sufficiently to obtain an independent take-off, like the one on your Dexta.

My personal experience with manoeuvring a loader from the lift handle is that it tends to be somewhat dangerous, because the lift handle does react much more sharply and abruptly than an external spool valve, with consequent unexpected downwards movements of the loader and things like that. Safety was not an item in the days of the grey Fergie....

It seems like you will have to choose between an authentic but inconvenient and potentially dangerous system, and the modern system with an independent pump at the front, as Steve wrote.

Ah, thank you. That was the answer I was searching for, however not the one I was hoping to find. I guess I will opt for an external pump to operate my loader on this little fellow. Thanks again for the information, and I hope this thread helps others as well.

You tractor WILL operate a loader quite happily without a problem, thousands of them work even now. The delay in the hydraulics lifting is due to there being no pressure in the system because the tractor lever is in the down position and the Pump has to bring the pressure back up again but it is NOT dangerous, it may be slow but NOT dangerous. You operate the tractor depending on how you have got it set-up, it is faster with an independent Pump but they are more expensive and not everyone wants that expense for doing a small job. There are more vintage tractors operating without a separate pump and spool valve than there are working with one.

Paul, There is a way to plumb into the internal hydraulics to power a loader. But you would have to chain the lift arms down and you wouldnt be able to use the 3pth. The best way to go is to get a front mounted pump. Then you would have live power for the loader.

Paul,
I had a front loader on a TEA, where you chain down the rear lift arms. On the year of TEA I have, there is a point to take hydraulics on the front right of the lift cover. By using a shutoff, you got to choose loader with chained down arms with the tap opened, or unchained arms and 3-point implements, with the tap closed.
This picture probably is self explanatory. Note if you do this the thread in the lift cover are pipe threads, but the ones in the hydraulic pump are not, so be careful!
Jim
