Long has low power but not engine.

I have an old long with a UTB motor D-121. (55hp I think).

I can rev the engine in 1st gear and it will barely move. The rest of the gears , forget it .... it's like it has no power to move but the engine sounds and runs fine.

I noticed it a week ago when I went to back up a hill and it wouldn't do it. , it should have enough power to do that. Now it will have to rev up all the way just to move it in 1st gear.


Any ideas ? I've scoured the internet trying to find answers.
 
As TF said, clutch problem. Should have an inch or a little more pedal free play. Also pressure plate can be adjusted through plate on clutch housing. You would need manual for that. Bought a 445 4wd that acted as yours, ending up adjusting the pressure plate assembly and was good to go for several years.
 
I looked in the clutch housing. There is oil.

Im afraid it's slipping on oil. Master main seal looks like. Bad deal. Gonna try some bars leaks.
