I have a cub cadet xt2 that will not start. Battery is fully charged and full gas tank and every-time I try to start with the key all I get is clicks. However I was able to start the engine by directly jumping the starter. After I had the engine running for a little bit I tried to go ahead and mow, but when I pressed the reverse pedal nothing happened. I tried the forward pedal and it made a high pitch straining noise "like you hear sometime when making a sharp tun or going up a hill" and it moved just a couple inches before stopping. The parking brake was off and the transmission disengage/engage lever on the back was all the way in, like it is supposed to be to drive the mower. Has anyone ever had any problems like this? I think it might be some bad safety switch that will not let the transmission engage? The mower is only about 3 years old with 50 hours on it. I would be surprised if the transmission already went bad. Anybody have an idea of whats wrong?
