Tractor Repair: ford 841 clutch, clutch pedal, clutch

Question
I have a ford 841 that the clutch works fine when you can get it in gear, it does not release, and also when you press in the clutch while driving you have to step on the brake to get it to release completely, is there a clutch brake on this old tractor that may need adjusting,also can you tell me how to identify the year of this tractor?Thanks in advance.

Answer
the clutch possibly needs adjusting. is there a lot of free play in the clutch pedal or is there pressure on the pedal straight away once you start pressing it you could have release bearing trouble or pressure plate trouble also try adjusting the clutch first
