Picked up a 53 with the hydraulic res under the gas tank. My question is what does this "box" do? My hydraulics (it has a 3pt ) work with the lever on the box (res) forward or back and the other hyd valve up at the clutch housing doesent care either way, as it is whats working the 3pt. My other super M had a totaly different set up. By the way, thanks to you folks for answering my question about that valve (at the clutch housing) a couple of weeks ago. I took off the cover on the bottom and low and behold there was only one bolt holding that valve in place.

The box under the gas tank is the hydraulic reservoir for the live pump and incorporates the “Liftall” valving.
The Liftall is for one-way (power lift/gravity drop) hydraulic cylinders. From your description it sounds as if your 3-point lift cylinder is set up for one-way operation by the Liftall.
The valve perched atop the clutch housing (frequently called the “Christmas tree” valve) is the optional 4-way remote valve. It is used to operate a 2-way (push/pull) hydraulic cylinders on mounted or towed equipment.
To use the 4-way valve you must first block off (either plug or valve off) the Liftall output ports. You then pull the Liftall lever back and latch it there. The system will now feed pressure to the 4-way valve.
Unfortunately you can't used both the Liftall and the remote 4-way at the same time.

Bob M, he says that the 3pt works with the lever on the box in either position...
Sounds like it's not hooked up the "factory" way to me.
biggerred, take a look at the hoses. I bet that the small hose comes out of the pump by the distributor and goes straight to that valve on the clutch housing.
It's bypassing the valve in the "box." That's why the valve on the box doesn't do anything. The box is only being used as a reservoir.
The way it's supposed to work is how Bob M describes. Yours is not wrong, just different.
