How do I install these front drive wheels?

Installation is straightforward and requires only basic tools. Remove the existing wheel nut, slide the old wheel off the spindle, align the replacement’s internal gear with the mower’s drive gear, and retighten the nut securely.

When should I replace the front drive wheels?

Replace the wheels if you notice reduced traction, grinding noises during forward motion, visible wear on the gear teeth, or wobble that affects steering. Preventative replacement can avoid further damage to the spindle or gearbox.

• Visible gear tooth wear or missing teeth.
• Wheel wobble or loose fit on the spindle.
• Loss of forward drive or slipping during engagement.
• Cracks, flat spots, or significant tread wear on the wheel surface.
