300 Utility Clutch with TA Problem

I have adjusted the clutch and TA according to the book and to the best of my ability with the condition of the tractor. The problems is when I press the clutch in and stop using the foot brake, and hold the foot brake on it is real hard to get the trany out of gear. Soon as I release the brake the trany shifts fine. Same thing if I have a bucket of dirt and the tractor is not able to free wheel. What’s up? Am I adjusting the clutch and TA wrong? Is the clutch not releasing enough?
Thanks, Joe
 
The book does not take into account the wear on pivots and pins in the system. The TA clutch is not being disengaged adequately and is hanging the pressure on the gears in the box. It will cause problems in the future if not adjusted. Look at the TA external clutch actuating lever where the shaft goes into the casting. (not the hand lever) Adjust this so it moves maybe 1/8th to 1/4" farther when the TA is in direct (forward) position, and the clutch pedal is down. Adjust it until the shifting is easy then a bit more. JimN
 
On some of the older tractors the ware on the linkage is sometimes wore bad and going by the book will not always give you the same results . So when you run into this you have to sorta FEEL your way through . First set the clutch free travel so that you have somewhere around 3/4 to 1 inch free travel , then remove the spring between the clutch arm to the T/A arm next remove the cover above the T/A clutch and adjust the linkage to the point where the T/A clutch throw out bearing is not touching the clutch fingers with about and 1/8th to 3/16ths of and inch clearance and see how that works . It is hard to explain as what i know comes from years of working on tractors i could show ya a lot easier then i can explain it . But since ya ain't my next door neighbor this will have to do . The book will get ya somewhat close but ya have to take into account that the book explains it for a new tractor or a tractor with little ware on the parts . Ware on the headed pins the slots in the clevis ware in the housings bushing all add up and make the book adjustment not work wright . So you use the book to get close and ya fine tune it by feel the rest of the way.
 
On a mechanical TA there are three adjustments you need to get correct.

1) free travel on the engine clutch

2) free travel on the TA clutch

3) the TA clutch shaft must move as soon as either the engine clutch pedal or the TA clutch lever is moved

To adjust the linkage start by disconnecting the main clutch linkage pin at the clutch shaft. Remove the interconnecting link and spring between the engine clutch shaft and TA clutch shaft.

Adjust the TA clutch linkage so that with the lever ahead and the pin in the slotted hole, the pin will move 3/16 on an inch between the front of the slot and the point where the release bearing contacts the levers on the clutch pressure plate. Hold the pin to the rear to compensate for worn pin and hole when making this measurement. That takes care of the first adjustment.

The next step is to set the engine clutch free travel. Hold the bottom of the clutch to the rear and adjust until you have an inch of free travel on the pedal. Holding the lever to the rear will compensate for worn pin and hole.

The last step is to connect the spring between the engine clutch shaft and the TA clutch shaft. Adjust the connecting link as short as possible without moving either shaft while inserting the pins.

Check the adjustment by watching the TA clutch shaft as you move either the engine clutch pedal or the TA lever. The TA clutch shaft should move as soon as either lever is moved.

Dynamic testing can be done by driving the front of the tractor up hill. With the TA ahead and the tractor in a forward gear, the engine clutch should should release about have way down. About 3/4 of the way down the TA clutch should release and the tractor begin to roll backward. This will ensure that the TA clutch engages before the engine clutch. If it does not engage first you will get a double shift when you release the clutch.
 
You have received excellant advice on adjusting clutch and ta linkage.
Maybe I missed something in the post but it seems like you are having trouble shifting when there is pressure on the trans gears. Which in my opinion is normal. Similar to when park on a grade it is hard to shift.
When you release the brakes the tractor is free to roll slightly releasing the tension on the trans gears and then it shifts easily.
Both my 300U's shift great and the clutches do not slip on hard pulls. Yet both of them will not shift when stopped on a grade or against something and then I have to rock the tractor slightly and it shifts easily.
You may not need to adjust your clutch at all, experiment and see if you can figure out the circumstances that make it hard to shift.

If it is hard to get out of gear it is an adjustment problem. If you have trouble getting it into gear and have to rock it slightly, that may be normal. Just a matter of getting the gear teeth to line up.
