I have a Case 1740. I was using it and the mounting plate for the gear box snapped. I didn't notice anything wrong until I eventually started losing power to the wheels and bucket. I've had the mount repaired and have installed but I still have very little power to the wheels and bucket. They move but slowly with no oompf. Any suggestions on what the problem might be or things that I can try to fix it?? Also the front pulley on the right looks like it shakes quite a bit and I'm curious if this is normal or if that is a problem as well?
