1975 John Deere 830

[rwolak]

I have a 75 John Deere 830 that won't move in reverse or shift into park. gear has welded itself to a shaft per the local John Deere dealer. Checking salvage yards for the whole rear end. Will other models cross fit? say from a 2020, 2030 or 2040?

Has tractor been operated with extremely low hyd oil level?? Will transmission operate in fwd in both low & high ranges? One limiting factor to interchanging(swapping) complete trans component is that 830 has open-center hyd system & only 820,830 & 2040 up to serial # 266749 have OC hyd systems.

Hi Jim,
Oil level has been fine, not sure what caused the lockup. Service manager said it looked like there was adequate oil present when they opened it up. Don't know yet if they checked the screen or filter. Only low range, forward is working.
Thanks

Was the tractor towed without the engine running and without the shifters in the correct place for towing, that can be an issue with some models, I'm not sure about this one.

Hasn’t been towed, I’ve owned it six plus years.
