I have a craftsman 42" riding mower and the clutch pedal started vibrating excessivly. When I slowed down I notice the mower has a jerking motion when driving forward. When the mower is in neutal you can still feel the vibration in the clutch pedal and the vibration stops after enganging the parking brake.
I would appreciate any sugestions that may be problem.
Check the drive belt. It probably has chunks missing or at least has flat spots (narrow spots) that cause the belt to jump every time it goes around a pulley. That will set up a heck of a vibration. Also check the pulleys for free movement. The drive belt is above the blade drive belt....

Thanks for everyone's input! This was very helpful.
I bought a new belt and when I went to change the belt I noticed that the belt had somehow been flipped so it was running inside-out on the pulleys. I flipped the old belt to have the correct side in and it fixed the problem.
Thanks again for the help!

Thanks for your input!
When I looked at the belt I noticed that somehow it got flipped inside-out. I turned the belt with the correct side facing the pulleys.
This seems to have fixed the problem and I appreciate your help!
