Clutch problems

1958 Cub. The clutch does not seem to be engaging? With the motor running if you push the clutch pedal in you cannot engage any gear. All it dose is grind. Stop the engine and you can shift into any gear. If you try to start the engine with it in gear and the clutch pedal depressed the tractor will try to move.
As always thanks for the help.
 
Has the tractor been sitting for a while and the clutch could have potentially rusted to the flywheel? That is what it sounds like to me.
 
Does that vintage Cub use the fiber
throw-out bearing? If so, it may have
reached the end of its "useful life
expectancy". Not to difficult to repair,
but it does require a split. Well you
are there, you just as well re-do the
clutch. jal-SD

Agree, need to know more information!

A suggestion one could make if it has been parked for months or years especially if outside in the weather could be way different, than if you just installed a new clutch this morning!

Also a bit of information on your experience level might help one know how to go about giving suggestions. Something I might do myself I would not even think about suggesting to someone I knew nothing about.
 
It sounds like it has been sitting for awhile. The clutch disc is stuck to the pressure plate. No worries.

Push/tow/shove the tractor to an open area where you can't run into anything.
Put it in gear, 1st gear will do nicely. Be aware of what is in front of you and start the engine. *Don't forget that the tractor is going to move when you do this.*

Push in and hold the clutch pedal down. Tap the brakes hard a few times. That should get the clutch unstuck. Use the tractor, or start and stop a few times to wear the rust off the pressure plate. Be prepared to do it all again, if the tractor sits for any extended length of time.

Glad you wrote this as I would not suggest it to someone I did not know.

Not trying to say anything against the original poster but!

All one has to do is watch a few Youtube videos to know there are some out there who when God said time to install the brain they put on a rain coat with the hood up! Because they thought he said RAIN!
 
To start with you have things backwards. Clutch is not disengaging so you cannot shift gears. Clutch engaged is when it it up and your moving around. That said you either have a clutch disk that is sticking to the flywheel or the pilot bearing is rusted up so the input shaft of the transmission does not stop spinning or the throw out bearing is bad or out of adjustment and the pressure plate is bad.

So not that all said fill in the blanks. Does the clutch pedal feel like it always has?? Or has it been parked for say a month or so??
 
How much free play do you have? If no free play then clutch needs adjustment probably. If it has been setting for long more likely what everybody has already said about disk stuck to flywheel. Could also be throw out bearing is shot. In any case if more than stuck to flywheel it is split time.
 
Push on the clutch pedal with your hand. If it feels pretty easy to push all the way to the the bottom of its travel, the clutch is not being
disengaged. Usually the throwout bearing (which is a graphite ring that presses against the pressure plate fingers) may be worn out. or the
pressure plate fingers are worn in there pivot, and must be pushed farther than they should. Both of these require a split. If there is a inch
or a little more of travel in the pedal, then it gets harder to push, the disk is likely rusted or goo stuck to the Flywheel. If this is what it
seems to be, the tractor can be driven around in second gear or third, where there is nothing to hit or avoid (field or big yard) with the pedal
pushed down, this gives vibration and force to split the stuck disk. applying the brakes suddenly can also shock the disc free. If it frees up,
blocking the pedal down while parked and not in use,cwill keep it from locking up again. Jim
 
To begin with,yes the tractor sat most of last summer. Had to pull it to the shop to give the fuel system a going over. Next I am no mechanic by any
means, but I am reasonable capable. Did a engine rebuild on my TO20 Ferguson with some book help. That all said looks to me like the bearing is
working as it should. Concerned about driving the tractor around the field as I am not as spry as I used to be and my property is not flat. I will jack up
the rear end and block the front. Try running it that way. Wish me luck and. THANKS.
