I split the tractor and took the clutch apart. Everything looks good and it works as it should. We put it together again and it still does it! If I start it in gear, the clutch stops the tractor.When I take it out of gear and go to put it in another gear it grinds. So, we took the side cover of where the shifter forks are and everything looks good and there is not to much wear on the forks. Trans looks good too. What is the problem?? Please help! Thanks.

Took pto off my B  and put it back  and it would stall down when letting clutch out in gear . It was the gear that put pto in gear out of the fork and sliding up against ring gear.  Just another idea.

Does it have a pilot bushing or is it a bearing? Did you inspect the bushing and shaft ? Does the CA have a wick in the crankshaft? Is the wick dried out and hard? Pictures of everything in various stages might show something.

After the clutch pedal is depressed the only connection between the flywheel and transmission is the drive shaft end into the flywheel pilot bushing. If you have a free wheeling transmission it does not take much friction at the pilot bushing to spin the drive shaft.
By free wheeling I mean that the transmission does not have the correct amount of drag.
 
Both bearings need to be tightened to have the type of drag you would have on a wheel bearing.  The counter shaft has a nut that is staked that would need tightened and re staked. the main shaft would need to be properly shimmed.
 
I thought I had a picture of the shimming of the main shaft but couldn't find it.
When you take the three bolts out and pull the seal you cah push back on the bearing and measure the depth to see how thick you need to shim between the seal retainer and the bearing. I use a .005 load.

It's a bushing

Is the bushing lubricated through a crankshaft wick?

There wasn't a wick in it.

You should be able to lock the clutch down and measure the clearance between the flywheel and the clutch plate with a feeler gage or shim stock to rule out clutch drag. 
A transmission that is really low on oil will spin fairly easy even if the bearings have the proper load.
 
If the wick is gone or to dry to seep oil, a dab of grease on the drive shaft or in the bushing will last for years. Most of the bushings are an oilite type material and takes very little lubrication. You wouldn't want to put enough grease that it would sling out to the clutch plate.

BobH, that happened to me one time with a pinto I rebuilt the motor on.  Killed most of a day trying to get it to go in place so it could be bolted up before a friend of my brothers stopped by.  He took a look at it and told us to pull the motor back up.  He looked it over and said to take the flywheel off and turn it over and we would be fine.   I had put it on backwards.  That's the last time I worked until 5 in the morning putting a motor back together.

Dick, how and where do you measure the bearing load?

You turn the main shaft with it out of gear. There is a tool to measure it and it has a value which I do not have the tool or the measured value however you feel for a slight drag as you would set the drag on a front wheel bearing. You get it to tight and the bearing will sound rough.
