What's wrong with my D-17 clutch?

I have a 1958 (series 1) D-17 gas:

Lately it has been getting harder and harder to get into gear (but wasn't slipping), so yesterday I replaced the clutch.

I bought a rebuilt plate and disc from AGCO with new pilot and release (throw-out) bearings.

Fired it up a few minutes ago, and it is doing the EXACT SAME THING!

What is going on? Could there be something wrong with the throw-out bearing mechanism? I did not look at it close when I had it apart, because I was sure it was the clutch. (The pilot bearing WAS bad)

Before I changed the clutch, I did try to adjust the clutch petal rod out, but that did not help either. According to my book, the D-17 does not have any adjustment for the throw-out clearances.

Help - I don't know what to do now....

I fixed the problem:

The new pressure plate fingers were too far away from the release bearing (1/2"). I think the problem is a worn pivot point on the release bearing throw-out fork.

But, to keep from having to split the tractor again, I screwed in the finger adjustment bolts until I had 3/16" clearance on all three fingers. I used a stack of feeler gauges for the measurement.

I could do this through the bottom inspection hole.

Anyway, it works now. Thanks to those who gave advice!

Could the transmission be low on oil? Oil helps to slow the gears and allow you to put it into gear. If low there could be enoght to still lube it, but make it slow to stop spinning. Can you look up inside the bellhousing and see how it is all working? The relaese linkage I mean? Do you have the correct amount of free play in the pedal? Too much free play will not allow the clutch to release, too little will have the linkage contacting the throwout bearing all the time, in the extreme it will cause the clutch to slip by holding it partially released. I don't know the correct free play for a D-17, but 1/2" to 3/4" is usually OK for most clutch linkages.

Are you sure the pressure plate is ok..??

May also be that it needs to be run-in some, before it will cleanly release..
