The Toro 133-2639 Wheel provides smooth movement and stable support for compatible walk-behind lawn mowers. This replacement wheel mounts to the mower’s axle and rotates as the machine moves across the lawn. It works by rolling along the ground while supporting the mower deck, allowing steady forward and backward motion during cutting. Built to match original equipment specifications, the wheel offers proper fit and alignment. Replacing a worn or damaged wheel restores consistent mower mobility and helps maintain even movement across turf during routine mowing tasks.
