3-Point Hitch Kama 554 TPH Arms Stuck Up

[RThomas]

Anyone know how to get the TPH arms to go down? They feel very solid in the full upright position and won't budge! Any help would be greatly appreciated. Rick

Does it have a knob with a set screw between your legs as you sit on the seat? If so this is the valve that controls the down motion of the 3 point lift. Try loosening it and see if it allows it to lower. You will need weight on the 3 point.

Chris has the right location. It's called the flow control valve, and that is a fairly universal location on Chinese tractors. You won't be able to turn the knob however, if there's a load on the lift arms. You must temporarily relieve that load with a jack or a lever, long enough to be able to turn the knob. Then carefully remove the jack or lever, and the lift arms should drop.

If the lift arms are not loaded AND the knob still refuses to turn, it's probably rusted shut. That requires disassembly and cleaning of the valve. Don't think there's a set screw on the KAMA, but I'd have to go out and look at mine in the morning to make sure.

No knob, just a large nut with an "O" ring wich I loosened untill fluid came out but the arms stayed up. I stood on the arms as I did this.

No load on the arms and there is a knob that is pointed to the right. I turned it then stood on the arms but they still won't go down.

Ok. No set screw on mine. It's just a knurled knob sticking out of a rectangular block. It may not be necessary in your case - but getting to the the valve body clearly involves removing the seat, then taking the cover off the sump. Anyway, when sitting on the seat - turning the knob to the right (clockwise) makes the lift arms drop faster. Obviously the opposite direction makes them drop slower. But there's really not very much adjustment in mine (compared to the smaller Chinese tractors); less than 1/2 turn from full left to full right.

Is it possible for the arms to go too high and get past center or something?

I can't comment on the Kamas, but it is on some Chinese tractors. If the stop is not set correctly on the TPH lever on a Jinma, for instance, it is possible to run the cylinder out so far it trashes the seals and can get stuck. I don't know if that can happen on a Kama or not.

Here is an informative thread by 3RRL on another forum. He has lots of pictures of the inside of the lift box.
