I have a Super M with a Farmhand loader mounted. It has a 3 spool valve and additional hydraulic reservoir. It is plumbed from the pressure side of the live pump into what appears to be a fitting installed in the drain port of the belly reservoir, then out of the front left liftall pressure fitting to the remote valve, then low pressure out of the valve to the loader reservoir, then from the reservoir to the return on the live pump.

It works with the liftall lever tied back (never tried it in any other position).

Does anyone know why the belly reservoir is on the pressure side instead of the return? Could there be a liftall pump on a super m and so both pumps are plumbed in series?

Should be a fairly simple mystery to solve.

Go in under the tractor's belly. I believe there's an access panel so you can get at the drive shaft for the belly pump. See if there's a drive shaft installed.

No drive shaft? Then Aces is right. When the live pump was installed, it was plumbed so the lift-all's control valve could be used to run the hydraulics. You can safely connect the IN side of the triple-spool valve to the pressure side of the pump, and eliminate the belly reservoir. It only holds 3 quarts of oil or something like that anyway.

Drive shaft? Then captaink is right. The pumps are working in tandem, though I don't really know what purpose that would serve.

Ty1 Going in the drain plug on the belly pump would do nothing, but pump the oil into the reservoir. There was a manifold that went on the back of the belly pump after the drive shaft was taken out that a live pump could go to and then the belly pump just became a control valve and use the out ports of the belly pump. Could this be what you have.

I�ve never seen this kind of setup. From what you describe, the pumps are plumbed in series, but the only reason I can think of for doing this is that the live pump is getting weak. I'm guessing that they tried to use the lift all pump for the loader but it didn�t have a large enough oil reservoir, so plumbed in the weak live pump to supply oil to the lift all reservoir for the lift all pump to power the loader. I�m not sure why not fix the live pump though�
