Additional information

This chute gearbox assembly, part number 618P09835, connects the chute control input to the discharge chute so turning the control results in smooth, controlled chute rotation. Proper gearbox operation helps keep the chute aligned and responsive during adjustments.

If the chute is hard to turn, slips out of position, or does not respond consistently when you operate the control, the gearbox assembly may be worn, damaged, or binding internally. Grinding, clicking, or uneven movement can also indicate internal gear issues.

Before starting the repair, disconnect the spark plug wire to prevent accidental starting. Install the gearbox squarely, align it with the chute control components, and confirm the chute rotates freely and holds position before reassembling.
