Additional information

This chute rotation worm drive shaft, part number 711-05186, works with the chute crank or control mechanism to rotate the discharge chute and hold it in position. Proper engagement between the worm shaft and mating gear helps maintain controlled, precise chute movement.

If the chute is hard to turn, slips out of position, or does not respond consistently when you adjust the control, the worm drive shaft may be worn, bent, or damaged. Grinding, binding, or uneven movement can also indicate an issue in the chute rotation system.

Before starting the repair, disconnect the spark plug wire to prevent accidental starting. Align the worm drive shaft correctly during installation and make sure it meshes smoothly with the mating gear so the chute rotates freely without binding.
