Farmall Super C fast hitch hose block

Rex Simpkins · Apr 19, 2014

I have researched the slow down pressure of Farmall Super C's and understand that one hole in the hose block is smaller than the other three, but I'll be darned if I can see one smaller than the others.

Just made new hoses and I am on the verge of saying screw it a just running hoses from valve to cylinder and just eliminate the hose block that is bolted to the hose guard.

Any idea's

I don"t think one hole is smaller. I believe the piston inside restricts the flow in one direction. Been many many years since I had one of them apart but I know I have modified the ones used on the 560 remote valves to get equal flow both directions. Purpose of block is to hold the load up as the spool valve used to raise and lower hitch has to have clearance in housing to move therefore always has some leakage.

Probably been 15 years since I worked on mine so can't remember exactly but I drilled 2 of the ports out, don't remember how much. I think if you study the ports you'll see one is already bored bigger than the rest, one of them can't be made any bigger, it may go in and off to the side so I opened up the other 2 holes. That hitch would go up instantly and take a half a day to lower it, now it lowers just a hair slower than it raises.

Here you go. The hose coming out of the spool valve goes to the right hand side of the block, the side with the valve head. That hose runs back and goes into the port on the cylinder that is on the outside of the of the cylinder. The hoses do not cross where they run under the seat. There are different opinions on here if you can bypass the valve or not. I would not do it for the simple reason of safety. I have a 5' rotary mower on mine, and it goes down fast enough with the valve.

Thanks fellows.

Removed check valve attached to seat, everything working much better.
I know I know thats the way they made it a it should be OK but it works better this way and if the slow down system was so great they would have continued it on the 240's

We put a "mostly there" fast hitch on the Super C a couple years ago.

Didn't have the seat base or the check valve block. Hooked it directly to an aftermarket hydraulic valve that I had laying around. Worked perfectly fine. Wasn't too fast.
