Hi I’m new to this forum and looking for some advice. I just bought this case backhoe yesterday it is a 1968 case 530 ck with the 4 cylinder gas motor. I was moving it around my yard today and all of a sudden it acts like the transmission is locked up.. I don’t believe it to be the brakes as if I put the outriggers out with the shuttle shift in neutral and the trans in neutral I can spin freely both rear tires. Now even with the tractor off the ground in every gear 1-4 in first or reverse on the shuttle shift lever or in high and low letting the clutch out kills the motor.. now in the transmission is in gear and shuttle shift is in neutral I can let the clutch out without it being locked up but if the transmission is in neutral and I shift the shuttle shift in forward or reverse it’s locked up. The lever feels like it’s shifting fine so I believe it to be inside. Any advice on what to inspect first? I’m not sure but I believe this is the dry clutch model. the shuttle shift is on the left side and the range shifter is in the right.
