424 End loader hydraulic connection

What is the best set up for connecting a loader to the hydraulic system on a 424?

The best way is to use a front crankshaft driven hydraulic pump like was available on the 2424.

What may be best for you will depend on how your tractor is currently configured. Do you have an auxiliary valve on the tractor?

Hi 417Ducth, your 424 should have similar
hydraulics as B-414,434,444,384, etc.

From archives:

Hi Ben, the B414 remote outlet that can be
controlled by 3pt lever is only single action and
a loader bucket requires a double acting cylinder.
The proper way to hook up a loader on a B414 is to
buy a set of hydraulic control valves, mount then
on the loader frame by the right side of the
steering wheel. Cut a section out of the high
pressure line from the hydraulic pump and connect
this line to inlet of hydraulic control valves,
connected outlet of hydraulic control valves to
remaining section of the high pressure line that
goes to the hydraulic reservoir under the seat. If
the hydraulic control valves have a low pressure
dump line connect this line into the hydraulic
filler plug behind the seat.

Hope this helps

Owen, thanks. Quiet frankly the loader is already on the tractor and has a open center control valve with relief already on it. I recently bought the tractor and the loader operates slowly and does not have the lifting capacity that it should. The tractor has power steering and the hydyraulic supply line for the loadder is attached to a port on the flow divider for the power steering. The return line for the loader attaches to a port on the front plate just below the seat. The power steering and the 3 point work just fine.

Below is what I had conveyed to Owen who also responded. As far as what you had sent me I had a local individual tell me the same thing. However, he was not familiar with the workings of the flow divider and I was wanting to be sure that I was not overlooking something. It would be great if I could see a hydraulic flow diagram for this valve so I could make sure that having the loader hooked up to it is in fact the main problem.

Thanks,

Dutch

I was wondering what the out come of this was, I have a 424 I bought with a pto driven aux pump and an aux tank for the loader, I am wanting to get rid of this setup and was thinking of tying into the tractor hydraulics. I thought about tapping into the pressure side of the pump with a T and running the pressure to the loader valves and then the return out of the valves would go in the drain plug on the back of the tractor. I also have power/hydraulic steering. any suggestions would be appreciated. thanks

If you put a Tee into the pressure side from the pump and then run it through your loader valve(s) and then back to the reservoir you will lose your steering except when the loader valves are in use and have a load on them. By installing a Tee before the flow divider valve all the flow will go in the path of lowest pressure. An open center loader valve will just allow all the flow to return to the reservoir and nothing will flow to the steering or hitch. If you use a closed center valve the hitch and steering will get flow when the valves are not being used but if you try to use the loader there will be no pressure since all the flow will still pass through the steering or hitch valves.

The engine driven pump is rated at 9 gpm and with power steering half of this flow goes to the steering and will not be available for the hitch or auxiliary valves. If you have an auxiliary valve or add one to the hitch hydraulics you will be limited to 4.5 gpm with the engine at rated speed. I'm sure you existing set up has much more flow than would be available from the engine driven pump.

The optional front PTO (engine crankshaft) for the 2424 is a 17 gpm pump that operated just the loader. That is what I have on my 2444 and makes the loader very useable even at low engine speeds.

What about coming right out of the hyd pump into the loader the valve and then the outlet would tie back into the original location that the pump tie into. with a front mounted pump what are you using as your hydraulic reservoir? I am going to start a new post to see if I can get anymore help. thanks

Splicing into the pressure line before the flow divider will provide all the flow from the pump to your loader valves but could also damage the pump. You would need a valve assembly with a relief valve but having the return flow from the valve going to the steering and hitch can cause excessive pressure in the system. The relief valve opens when the pressure between the inlet side of the valve exceeds the the preset psi as compared to the outlet side of the valve. Since you would be using the flow from the outlet side to to feed the power steering and hitch, when those parts of the system are under load enough to open the relief for their part of the system, the pressure will rise on their inlet side.

If you have a loader valve with a relief valve with a relief setting of 2000 psi the pressure at the pump will be 2000 psi. If you also have a steering relief pressure setting of 2000 psi if you lift the maximum load with the loader so that the relief pressure has been reached at that valve and then turn the steering to its maximum load the relief pressures will be added together so that the pump pressure will now be 4000 psi rather than the 2000 psi that the system was designed for.

The way to avoid combining the relief pressures would be to have the relief flow from the loader valve return directly to the reservoir. If you were to do that when ever the loader valve reached its relief pressure all the flow would return to the reservoir without going to the steering or hitch.

Tractors with a from mounted 17 GPM pump used the transmission and rear frame as the reservoir. Oil is drawn up through the upper hydraulic reservoir, through a loader mounter filter and then to the pump. Oil returning from the loader valves is returned to the top of the hydraulic reservoir. A stand pipe inside the reservoir keeps the oil at the correct level while allowing the excess to flow back into the rear frame.

Ok i think that makes sense, I also just noticed that on the case IH parts site for a factory loader it looks like they were pulling the pressure from the factory filter under the steering wheel. my line that is running off that is going to the aux valve to the left of the seat (the one i want to use for hyd toplink) can I put a T in the filter housing and run it to the loader valves then dump it into the hyd tank fill port for the return?
