Ford 4500.... 90% of the time when you
push the clutch it is nearly impossible
to get it in any gear, just grinds
horribly. 10% if the time it slips
right in perfect. After it's in gear
you can shift it into any gear (forward
or reverse) just fine. Clutch always
works fine stopping the tractor,
doesn't stick. Any adjustments?
Also, compared to our gas fords this
thing idles really fast, can't find the
screw on the carb to slow the idle, I'm
joking!! Lol. Any way to idle it down a
bit? I did use it for about an hour
today. Dug up some stumps. Lovin'it!
Also used the clamp on forks to load a
Farmall Cub mower, much better than
that Massey I sold.

Clutch could be a number of things. Pilot bearing hang up till it warms up and then works. Or clutch disk has some rust on it and hangs up for a short time and as it warms up releases better. As for adjustment never seen a clutch pedal that didn't have some sort of adjustment unless it was hyd

If you shut it off put it in gear and restart it does it move with letting the clutch out

After you said year got to thinkin, Proably has button clutch. Could be pilot brg or rust on splines/ disc

There should be an adjustment, usually 1/2 to 3/4 inch pedal free play at the top before the release bearing contacts the pp.

The fast idle is probably the offender. Can you push the throttle closed at the carb? Possibly the linkage is holding the throttle off the idle stop. If it still won't idle down with the linkage out of the picture, look for worn throttle shaft, bent, loose, throttle plate or plate installed wrong on the shaft, backward, upside down. Vacuum leak?

Have you checked the trans oil level? Oil acts as a brake on the spinning trans parts. Low oil lets it spin longer.

And could be the clutch disc is worn flat, beyond the grooves cut in the disc. Those are air vents to break the vacuum behind the disc and flywheel or pp. An oily clutch will also sometimes stick. A dry or worn input shaft will sometimes hold the disc from floating as it should. A failing pilot bearing can cause the clutch to fail to release.

What RPM are you seeing at the fast idle? I would suggest that a farm tractor diesel idle should be somewhere between 600 and 800 RPM. Some of the older backhoes would have idle speeds of up to 1200 RPM depending on the brand. Are you seeing something above that? What does the operator manual say about it? A backhoe is not a farm tractor and will have somethings set up differently.
Does the throttle move all the way through it movement? There should be a foot throttle in addition to the hand throttle as it looks like yours might have spent some time outside check for rust, sticky connections or linkages out of adjustment.

Pedal free play is all you can adjust on the clutch. Unless the pedal has ridiculously too much free play, that's not the problem.

It's just hanging up ever so slightly causing the input shaft to keep turning. If it were bad, it would start spinning between shifts, not just when you let the clutch out in neutral.

Probably the pilot bearing in the flywheel. Not much you can do short of splitting it, which is a job on a machine like this.

The tractor had been sitting, right? It should get better with use and heat cycles.

Sv if I start it in gear with clutch down it won't move. Well.... until I let clutch out

No idea what rpm, tach ain't working. Just seems way faster than our gas burners
