I have purchased a 574 with a clutch problem, I knew it going in though. The clutch will release, but only at the bottom 1/4 inch of pedal and the adjuster rod is fully extended. I removed the inspection plate and the throughout bearing looks good and turns fine, also judging by the distance the pressure plate is from the steel plate that the pads are rivited to, it is in reasonably good condition. The clutch does not slip at all. The fingers on the pressure plate do not appear to be in good condition though. Has anyone had this experience, or perhaps a picture of the fingers that I can compare to mine. Thanks for all the help everyone has been so far.

If the fingers look bad then most likley the clutch pedal has been ridden and worn them away or the release bearing is siezed. Check the holes in the linkage are not elongated and the adjuster rod and the clevis pin are in good condition. Check also the bushes and clutch cross shaft are not worn causing lost motion in the linkage. The 574 will not have the wear plate in, they came out in 85 series production and tractors so fitted have no pedal return spring. As the clutch wears the gap between the fingers and bearing will diminish anyway.

574 cluch problem.What usely happens here is somebody has probaly put a cluch in this tractor and pulled it together with the bolts.when this happens they usely don't have the splines lined.the clucth or pressure plate splines will not aline the shafts will put undo pressure on the plate splines and warp both plates.then when they do finaly spline by pulling together the damage is already done.this will push the center of both plates torward flywheel they will not come back to shape.if you have to put a cluch in this tractor put the (pr pl) on P T O shaft and cluch plate in front of it roll the tractor together snug the bolts then go under the tractor put the bolts in P PLATE up through the inspection opening.this will prevent damage to the shafts and plates.

Someone may have replaced the disk and not the PP. If the finger tip screws will adjust outward to compensate for the adjustment, I would try that first. Turn them all an equal amount, count turns. If they are abused as stated, you may be able to replace them alone to cure the problem. The throwout fork may be twisted on the shaft. (I'm not sure if this tractor has that style) If it does, the pin in the connection may be partiallyt sheared. Good luck repairing without splitting. JimN

Hi Bewildered, wonder if someone installed a 12" clutch instead of 11" and its is riding up on the edge of flywheel? Clutch is installed backwards? Springs on clutch plate should be away from flywheel, but I believe this would cause center of clutch plate to limit on flywheel.
Wrong release bearing? Should be about 3/4" thick with a Teflon wear surface towards the pressure plate fingers.
