Hello all: I just purchased a Snapper front engine rider, Model: LT115D411B, Ser. 25425177, I got the engine running and taking it for a test run, but when the tractor starts moving you feel this vibration in the seat, the plate that the gear selector rod rides in, ( by the drive disc ) just bounces up and down when moving in forward or reverse, there is a heavy spring on this plate, is the drive disc causing this, ( I did notice a small crack in the rubber on the disc.) or where do I need to look to fix this, there rear plate is gone so all the drive parts are exposed..Thanks in advance.. Ed
