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.

Anything's possible I guess, if perhaps the internal stop broke off or some such thing. All I can say is that I've got a combined 10+ years and over 800 hours on my two. No lift problems. So I can't attest personally to any issues with lifting them too high

I'm going to do some further investigation today, start by looking into the hyd. valve assy. Thanks for the input. I'll post my findings.
I can only speak of my kama ts354c (2004). The lift box has a lever on the rear left corner that will lock the lift in the raised position. I moved this lever accidentally one time and spent a lot of time trying to find the problem. Check it out. You may be lucky.

I have a TS354C and a KM454 (the 3 cylinder version of the OP's 4 cylinder KM554). The 354 and 454/554 are completely different tractors.
That lever on yours is the PTO engage/disengage. The hydraulics are run by a PTO pump. If/when you accidentally disengage the 354 PTO, you disable your hydraulics completely (except steering). The 454/554 has no such lever. The recommended solution to your lever problem is a hacksaw. Cut the lever down so there's only about 4 inches remaining, then leave it permanently in the engaged position.
//greg//
apples and oranges greg. Please understand I know of the lever you are referring too. But I am referring to a different lever. As I stated it locked the lift in the raised position. I know what I am talking about on this matter. You need to be open to new ideas from people who have some knowlodge of their tractors. I do not like to be told I don't know what I am talking about. Have a great day

That door swings both ways sir. What you're apparently talking about is the TS354C hydraulic diverter valve. When hydraulic fluid is needed on the single remote, that valve diverts fluid from the lift to the remote (pressurized output, gravity return). When the valve is turned to divert fluid to the remote, the rear lift is disabled. Either/or. Ordinarily that valve is controlled by a a simple hex head bolt sticking out of the sump (above the external filter housing). So someone must have tack-welded a handle on yours.
Understand also that - even though our TS354Cs are made by KAMA - they're in the CUT category. The KM454/554 is up in the UT category. As such they're equipped with two sets of hydraulic remotes with associated flow control valves under the left floorboard (pressurized both ways). As such, we're dealing here with a completely different tractor configuration than yours. So thanks for the input, but it's wholly inapplicable to this particular KM554 topic.

once again greg you are wrong. please refer to your kama ts series parts catalogue. mine is a 2004 model ts354c. on page #97 is the lifter assembly. the part #24 is named lock shaft sub-assembly. this is the lever I am referring to. in my tractor operation manual on page #34 it shows the lifter assembly. part # 3 of figure 3-13 is the lock shaft. the lever is on this shaft. i hope this helps to clear this up. now my lift box may be different then yours but as I stated this is what will hold my lift in the raised position. I was offering information that may be helpful. if it was unclear sorry but do not assume you know what I am talking about. I was trying to help not get in a debate. this is why I chose not to post must of the time.

Hmmm, that "lockshaft" was apparently either problematic or redundant. Because it's not on any of the 2005/2006 models I've seen. Matter of fact, there's not even a hole in the sump at that spot. But continuing to beat this very dead horse is only prolonging the agony. I'm surprised you didn't figure out that figure 3-13 is mislabeled. Item 3 is the drain plug. The "lockshaft" - on those tractors so equipped - is on the other side of the lift box. A quick look at your own tractor should quickly confirm this.
Nonetheless, you persist in ignoring the BIG point. Despite the fact that this topic involves a KAMA brand tractor, not all KAMA are made the same. We already found that out with your "lockshaft". So again: the KM454/554 tractors have an entirely different hydraulic configuration than does your TS354C - to include the fact that there's no "lockshaft".
