John Deere stx 38 will not travel forward nor reverse.. Few days prior to this my tire went flat. So I tried driving the mower to my garage and the tire came completely off the rim where my mower would not travel anymore. So I turned the mower off and pushed it the rest of the way. Got a new tire installed and when I started mower and got ready to cut some grass it will not travel in forward not reverse. No belts or pulleys spin when mower is started. When I press down clutch no movement. When I put mower into gear no movement under deck either.. Did I damage something while trying to drive mower with flat tire back to garage? I look at clutch linkage and it has movement up to the transaxle... Scratching my head on this... Any ideas?
