Actually the main clutch has nothing to do with the transmission being hard to get out of gear in this situation.
What actually happens is the TA clutch is not fully released when the main clutch is released. As the tractor rolls backwards the ramp and rollers lock up in the TA and since the TA clutch is not released the TA assembly cannot turn backwards and there is pressure on the transmission gears as the tractor is held in place. Pulling back on the TA lever will release the TA clutch which allows the planetary gears in the TA to spin so the transmission input shaft can rotate backwards releasing any pressure on the transmission gears. The transmission can the be shifted.
The purpose of the link between the main clutch shaft arm ans the TA clutch shaft arm is to release the TA clutch just slightly after the main clutch is released as the clutch pedal is pushed down. When the clutch pedal is released the TA clutch engages just before the main clutch. If the TA clutch is not released you will have shifting problems. If the TA clutch is released before the main clutch, as the pedal is released the main clutch will engage and the tractor will start to move with the TA pulling on the low side. As you continue to release the pedal you will feel the tractor shift speeds as the TA clutch locks up.
