Gear shift sticks under load

Greeting,

I have 560Dwith an F-11 loader/bale grapple and a new problem.

When I push into a pile of hay or dirt the gear shift binds and I cannot get to neutral. I have had to pull the machine backwards an inch or 3 and that frees up the gear shift lever. It have never had this happen before yesterday. On a flat surface it shifts easily.

To model the behavior I can start up a steep rise/terrace. If I push the clutch in it stops and I cannot take it out of gear. If I drive on over terrace it shifts freely..

I have read that if the TA is not adjusted the clutches can bind the transmission. I have tried adjusting the ta but to no effect so far. I did have ta action before the adjustment but now nothing. I adjusted the long and short linkages for 1/8 inch of travell. I found this in a video of adjusting the ta for a 300

What should I try next

I adjust a worn set of linkages so that the pedal releases the shifter when pushed down 1/3 the distance to the full pedal travel from the place where the main clutch begins to move the tractor. Set the master clutch freeplay, (1.25 inches from the platform measured at the point where the pedal arm touches the platform. Next, tape a wooden 12" ruler next to the clutch arm so it sticks out forward past the pedal about 6 inches. With clear space ahead of the tractor, put it in first direct, and let out the clutch slowly. as you begin to move note the location of the beginning of tractor movement on the ruler (the number doesn't matter, it only allows you to know where the clutch starts to move the tractor.)
Stop the tractor, and mark that spot on the ruler.
With it shut off, and looking at the ruler, note how far it is from that mark, to fully pushed pedal. Set the TA clutch so it releases at 1/3 that distance. This setting allows the pedal push to release both clutches when pushed (correctly) to its travel stop, and assures that the TA clutch is fully engaged before the master clutch begins to move the power into the gears. The TA lever is adjusted so it works at 1/2 the lever stroke to transfer from TA to Direct. Jim

try pulling the ta back into low to shift

If the TA isn't working after your adjustment, you adjusted it the wrong way.

Another possibility is that the TA clutch throwout bearing has failed due to being out of adjustment for a long time. There's an inspection cover on top of the transmission below the gas tank for that. If the throwout bearing is roasted or there's something wrong with the pressure plate, the tractor will need to be split to replace the TA clutch. Luckily it's not a full TA job, so not as involved and several hundred dollars less expensive.

Well you did not do it correctly , Lets start off with the main clutch , get one inch of free travel on the main clutch between the flooor plate and the clutch pedal with all the other linkage unhooked even the springs , next pull the small hmped back plate off the top of the clutch housing to see the T / A clutch and the T/A clutch release bearing , re hook you main clutch return spring and remove the headed pin on the bell crank from the main clutch to T/A clutch and adjust the clevis so that the T/A release bearing will touch the fingers and the pin will slide in , this is done with the small spring unhooked and you are holding the T/A release bearing against the fingers . Once you have it adjusted to the point where the headed pin will slide in then you back off that adjustment to give you about 1/8th to 3/16th of clearance between the pin and the clevis and allows clearance between the release bearing and the T/A clutch fingers . What you are after is to have the T/A clutch to disengage when you depress the main clutch , this will unload the holding affect that the T/A is causing on the transmission . Due to age , ware on all points ya can no longer go BY THE BOOK or by someones video , This comes with years of working on them and getting them to work . You have ware on the main clutch cross shaft , ware in the housings , ware on the pins the clutch pedal , ware in the clevis , ware on the T/A cross shaft and holes in the housing and you have excess movement everywhere so now it becomes a FEEL THING and not a Spec. thing .

Thank you for the hard earned wisdom. I will work through the steps you have developed. Many thanks
