Hey guys have a question our 730 has been having some issues with the three point not wanting to raise and lower porperly. It seems to hang up on the draft control but you can move it and then it works. However it is very slow and works when it does not have a load on it. We tried lifting a 4 row cultivator with it today and it would do nothing. It sounds like the oil is being pumped but nothing is happening. Is the hydralic pump out of the tractor or is the cylinder for the three point bad. This is the first one on the farm and haven't had much experience with it any help would be appreciated.

Mine was acting the same way after some water made it's way in with the tranny (hyd) oil....changed the oil , no luck , took a swing at some Lucas trans conditioner, a whole quart I believe....3 point was working like new in minutes ....your results may vary , but it was a quick ,cheap fix, over 5 years ago...no problems since...if that doesent work , mEl had the next step....Shawn

If I were to look at the tractor the first thing I would do is plug a gage into a remote and check the system pressure. If that is correct then I would remove the DOM valve and give it a thorough cleaning, disassemble the raise plunger and clean it internally as it will get plugged with sediment and cause a severe delay in raise response. You should have a copy of the service manual page that describes this disassembly and reassembly operation as there is an adjustment procedure to the adjustable needle which is internal to the raise plunger. You should make sure that the lowering plunger is seating properly and the ball that operates it is not binding in its hole and keeping the plunger from seating. The screw adjustment on the lowering plunger SHOULD NOT BE CHANGED as it's length is factory set and a procedure with a dial indicator and multiple assembly and disassembly is required to find its proper length setting. The timing between raise activation and lowering plunger closing is what is affected and has everything to do with draft sensitivity. If you have catching in the linkage you must find out the reason for that as well. If you proceed on your own I would again suggest a Case factory service manual as it gives step by step instructions. Going out on a liitle bit of a limb here but any manual through the seventy series should give the same basic info as far as internal stuff , the difference being in the external linkage, it may be a bit easier to find a manual if you have more tractor options to look for. mEl,
