Last time I had my 2610 out (3 weeks or so ago) it was hard shifting the main transmission as if the clutch were not working properly. I finished mowing and managed to back it into the barn. Went out yesterday and started it but it will not move. I can run through the gears while it sits running but when I release the clutch pedal- nothing happens. Not even a grunt or slight catch. Is the clutch shot or just stuck? Can't run it up against anything since it won't move. Hours show 376 on the meter. Any help is most appreciated.
