Hydraulic take-off and return points
There are three pressure oil delivery points on the lift cover and anyone of these can be used to operate an auxiliary cylinder. This is how the MF operator's Instruction Book shows them:
To be able to control both directions of the cylinder it's far better to acquire a diverter valve like the TISCO TS-300 which, as far as I know, is a fairly standard valve used on many brands of tractor, so I would think most ag equipment dealers would have access to one. Here's the installation instructions for the TISCO valve.
Sparex also has a diverter valve similar to the TISCO valve. It is shown as #14 on page 5 of their catalogue, and it replaces the existing transfer plate MF part 180 908 M1 just as the TISCO one does.
Now, before I fully recommend the TISCO valve, I need to mention that a fellow FE35 owner in Ontario bought one and ran into a couple of smaller problems.
Here is what he wrote:
Here's a quick snapshot of my old transfer plate showing the opening with the slightly relieved edge to accommodate the O-ring where the pressure stand pipe fits up into, and the smaller hole below (with a smaller O-ring) which is the return orifice.
