IH 574 Does not move

[baazfarms]

Hello All
I have 1974 IH574, it does not move or moves very slowly for a few feet and stops. AT full RPM, it moves slightly better and further. PTO, bucket, 3 point all work fine. I have changed fluid, filter, cleaned two valves in MCV. When I took off, the valve that is toward the back, cleaned it and put back. The tractor moved about 50-70 feet as if situation got solved and then came to a stop and start behaving same. Any Help please, Thank you in advance!

Hello baazfarms, welcome to YT! I’m not the best guy to answer your question due to not knowing these models real well. What type of transmission does it have? I am guessing you have made sure the clutch is adjusted with some free play? I also assume it is not a hydro drive? Does it have a reverser? Or a two speed shift on the go… aka TA?

Hi used red MN, Thank you! per my research its hydraulics TA helps it move.

Hi used red MN, Thank you! per my research its hydraulics TA helps it move.

Please clarify this, in a selected gear you can shift into hi/lo without the clutch this is how it worked when it worked correctly? We need you to answer questions like the clutch free play was checked. Since you’re new to the forum we have no idea of your mechanical abilities, so for us to know where we’re at you need to provide such answers please take no offense to this. You apparently have some mechanical prowess if you went into the MCV, of course these days YouTube often raises the “gusty” level for many. You may indeed have very good mechanical knowledge and experience, we can only decipher that over time.

Not an IH guy but trying to help. I looked on Tractor Data. Your model was UK built and came with gear driven or hydrostatic transmissions, which it sounds like you have. It also said the hydrostats are rare in the states, mostly sold in Europe.

Hydrostatic or gear drive?

Got some questions for you (some reiterating what others have said):
Is it a gear drive or hydrostatic model?
If gear drive, does it have a TA?
Does the tractor grind gears at all once it stops moving?
Does it move better if you drop it in the lowest gear possible?
Have you tried adjusting your clutch freeplay?
Are you sure your parking brake is not on?

Hi MN, yes I have o use clutch to move hi/lo, clutch works fine. I have to admit I'm not very familiar with lingo but I would consider moderate with my mechanical ability although I didn't grow up in this atmosphere. No offense taken, I agree with your Youtube observation and I'm one of those LOL. It is that nobody wants to work on such old tractor.

Thank you Powered by IH, I'm not sure but Mike mentioned that it is hydrostatic. No it does not grind gears, when I start the tractor, starts well but after putting in gear, it does not move for a bit and then start moving very very slowly and then move few feet and comes to stop. at full RPM, it moves for several feet and then stops. shifting gears does not seems to have effect on it, I can try adjusting clutch freeplay. No it is not in parking brakes.

I'm not sure per Mike NE Ohio it is hydrostatic.

I can try adjusting clutch freeplay.

The clutch pedal pushes a bearing against fingers on the clutch pressure plate which releases the clutch from the drive position, disengaging it we call it in technical terms. As the lined clutch plate wears it gets thinner decreasing the free play. The free play ensures the clutch is in its engaged position driving the tractor. When there is no free play the clutch linkage pushes the clutch pedal up towards it stop bumper and the throw out bearing then starts holding the release fingers partly in the disengaged position essentially fooling the clutch into thinking the clutch pedal is being held partially down at which point it starts releasing or disengaging the clutch and the tractor stops being driven by the engine. Push the clutch pedal down by hand, there should be a bit of distance somewhere under an inch that it pushes easily. Then when the bearing contacts the fingers and starts releasing the clutch the resistance will become greater. As a rough setting use 3/4” movement for the free play at the foot pedal surface.

Welcome to YT.
Just to confirm your 574 has a T/A. The T/A is the lever on the left side of the steering column and it is a mirror image of the throttle lever.
Pushed forward it is in High Direct Drive via a hydraulically activated clutch pack. The hydraulic pressure is supplied by the T/A pump in the bottom of the torque tube. When in Low, the drive is by a mechanical sprag clutch with a brake disk that locks the driving shaft to the sprag so the tractor does not free wheel on the down hill like the older Farmall T/A and MF Multi-Power.
On this series of IH Doncaster, UK, 54/74/84/85/95/32XX/42XX tractors, it is very difficult to determine if the problem is a bad T/A or a slipping clutch.
First test: Does the tractor have the same problem if the T/A is in the Low position or only in the High position?
Second test: Will it move in LO gear LO Range?
Report back on your findings.
