If the rods are not engaged at all, wiggle them to release them. Lift the back of the tractor and access the transmission release levers from the rear. Sometimes, the transmission release levers also get jammed if something hits them (such as rocks if you have bumpy terrain). Mud and grime can accumulate on these rods and get them stuck. Their role is to disengage the transmission so that the mower can roll back and forth. The transmission release levers are two rods located at the back of the mower, under the hitch. Replace the C-clip with an appropriate size one to fix the problem. Remove the battery and locate the steel rod linkage. A C-clip connects the rod to the transmission, and if it breaks, pushing the pedal won’t engage the transmission.
