Just helping out a local rugby club. They have a MF 35 with a Tri Max Procut. Problem the 3 point link does not do anything. Not up or down or any indication of power/pressure. Is there a control valve somewhere that transfer the power to the 3 point ? PTO works fine.

Steve, from ancient memory I think there is either a locking lever or twist valve that locks the hydraulics, are they all the way up? Other point is check linkage is actually moving between the lever and box and that oil is up to level on back end.
Sumo?

A day without sunshine is like errrm night.

Hi Steve, Barry is right I think, again from distant memory there is a screw control located at the bottom front of the seat, try screwing it all the way out, I THINK it controls flow and that all the way in it isolates the 3 point linkage.

....Be the best you can....

Steve,

Have had a couple of these -

One had an over-centre locking lever under the front of the seat which had three positions - linkage locked and flow to trailer tipping pipe, flow to 3 point linkage, and divert to front loader.

Another had a screw valve again on the bulkhead under the front of the seat which restricted the flow to the linkage slowing, or eventually stopping the hydraulics. It also had a mechanical lock on the linkage - e.g. two pins which had to be removed which otherwise locked the linkage into a pre-set position. The preset position could be adjusted by a sliding bar.

Checking the lever is actually moving the linkage and valves would be a good start - does trying to lift the linkage knock the engine down?

Worryingly also had an MF 135 which wouldn't lift the linkage because the relief valve had failed - needed the tractor splitting for repairs.

Also, as an aside, had a Massey Harris Ferguson 30 which had paraffin priming, a brass button on the gearbox which had to be pressed in with your right ankle\heel, and the starter could then be engaged by moving the gear column into "S".

Regards.

Green is not necessarily beautiful.

What a memory you have Barry, to remember that far back!
