Ford Workmaster 641 clutch will not engage, I think

When running my workmaster 641 tractor and clutch is pushed down the tractor gear pushes you forward.

In the past I could press the clutch and the tractor would not move andthen I could shift gears.
I turned the clutch pedal adjustment did not help.

Is it possible my clutch disc is stuck closed?
Is there a way to unstick it without takeing the tractor apart?


So what is involved in fixing the clutch? I do have some mechanical abilities.

Thanks you for your help
All comments welcome
 
Running as in just the tractor or do you maybe have a brush hog on when it does this??
If just the tractor the clutch disk may be getting to much oil on it which can make them sticky or you have let it sit a while and the flywheel is getting rusty and stick to the disk. If that is so pull the starter off and use a can of spray brake cleaner to clean it up. Turn the engine a full 360 while doing that.
If you have a brush hog on and no ORC then what happens if normal and you need an ORC
 

THANK YOU.

This is my husband tractor. It sat for a while and we(my husband and I) found the gear oil had not been changed for years. The gear oil was white so it had water in it. We change the gear oil. I am guessing this had a little something to do with it.

We will do as you suggested.

Thank you for your help
 
You do know you do not shift gears on the go don't you?? Also when the transmission oil is cold it tends to make the machine drive on a little bit after pushing the clutch down
 
If the tractor moves as though the clutch pedal is up, and will not release to shift or even get it into gear do the following:
Move the tractor in neutral so it points to open land to allow safe driving and effort to free the clutch. (It probably just stuck/rusted to the flywheel)
Put a block or strap on the pedal to hold it down as though your foot was pushing it down.
Put the tractor in a medium speed gear. Start the engine and drive it forward. Use the brakes to apply force to the clutch. (it might need near full throttle)

We got the clutch to loosen up. We applied brakes and this helped, also ran the tractor for an a while this helped. Now we can use the tractor again. Thanks for the assistance.

We understand about shifting learned the hard way. So the clutch is cased in housing to hold transmission fluid. If the transmission fluid gets moisture in it this will make the clutch plate stick.
Is this correct thinking?
We changed the transmission fluid today it was a cream colored. We have not had this tractor to long and who knows when the transmission fluid was changed (that's my disclaimer) anyway.

Please give a simple way to understand a clutch, how it works.

Thanks for the help
 
Water in the oil will not make a clutch plate stick.
As for explaining a clutch about the easiest way to explain it is the clutch has a pressure plate which of bolted to the flywheel. There is a disk between the flywheel and that pressure plate. When you push the clutch down that makes the pressure plate move to release the disk. Sort of like if you take 2 fingers and hold a piece of paper when you push the clutch down it would be like opening your fingers to release the paper so in simple ways that is how a clutch works
 
When you park it set a cement block on the clutch pedal or block it down in some way. Sounds like you have a rust or oil problem with the clutch. Also look under it you should see a cotter pin sticking out the bottom of the bell housing. Make sure it is clean and free to move. The cotter pin it there to drain oil and water out of the bell housing so as to keep from having those problems
 

We wondered why the cotter pin was there. So we will make sure it moves freely. Also we will rig a way to keep the clutch pedal in the down position when not being used. My husband does not use the little workmaster that much.

I use my Ford 850 a lot during warm weather. So for winter how do I set my tractor up for the winter.
I put tarps over it.

Thanks for the schooling.
 
(quoted from post at 10:00:47 09/08/14) Tarps trap condensation which is worse then snow or rain on one. I prefer a pole shed but I know some people do not have that option

I found this old set of covers which where made to go on a old ford tractor for cold weather use they have the Ford logo on them. It looks like they cover the sides and have sort of a plastic window for the front where the drive sets, they are made of canvas. Maybe they could give some protection from rain and let air get to the tractor. What do you think.
 
(quoted from post at 11:17:03 09/08/14) Those old heat hosred cab work well for both the tractor and the driver since it funnels the engine heat on to the driver

Cool I will use them.

Thanks for the help

I have three tractors under one tarp. I just roll the two ends up a little to let the air through. Seems to work so far.

Maybe tarp and ford side covers.

Do you set your clutch to being open by pressing it down for cold winter?
