While moving/dumping dirt with my loader, I pushed my clutch in to change gears and back up. I felt something give in the clutch pedal and then was unable to get the tractor to move again. The clutch seems to be disconnected but nothing I see looking at the linkage outside under the tractor seems disconnected. I'm also able to move the shift and drive levers in and out of gear without grinding or depressing the clutch. It does'n't seem to matter whether it's in high or low, in or out of 4 wheel drive. Is what's disconnected possible to fix fairly easily without taking in to the dealer? The clutch has been adjusted several times in the past to continue adequate engagement. Thanks.
