I have a L 4350 4x4 Kubota tractor. It has the manual shift with high low and the you have one lever for forward reverse. I just bought it tested it good I thought . Now the clutch just hits the floor bottoming out it just stays there and will not stop tractor at all. I tried to adjust but there is no difference. There is a spring that is suppose to pull the pedal back up but it does not. When I unhook the linkage that goes to the clutch I can move the lever that is suppose to work the clutch and it moves free like it is not doing anything. What do y'all think happened? Will I need to split it?
