Fast Hitch won't go low enough

RyanV · Mar 27, 2009

I have a Farmall 504 with a fast hitch and 3 point conversion (top link bolt on & arms slide into fast hitch) that will not lower far enough to engage a middle buster. Can someone please help! Thanks in advance.

That's the problem with conversions. Either they don't lift high enough to get the implement off the ground, or they lift too high.

Sounds like maybe the arms you got have an upturn at the end where the ball socket is? You need to trade them for some arms that are straight.

One thing to check would be to see if your ram has a collar on it restricting how far in it can go.

Not a bad idea, but I think the 504 has an internal cylinder for the 3pt/fast hitch. No limiting collar.

That gives me an idea for something else to look at, though.

The upper lift arms are the same for 3pt and fast hitch if I'm not mistaken. The difference is in the position that they're mounted. I think they're on a splined shaft and can be "clocked" to different positions for 3pt or fast hitch operation. Someone may have clocked the lift arms higher to get the fast hitch to lift higher. By doing this they limited how far down the fast hitch will go.

A fast hitch should drop almost to the ground at least that's how it was on the old 560. With the drawbar and extension plate installed, the tip of the plate would just about touch the ground with the hitch all the way down.
