Genuine OEM Part 139-3649
MICHELIN® X® TWEEL® Turf Airless Radial Tires (24") (Part # 139-3649)
A MICHELIN® X® TWEEL® airless radial tire is a single unit that replaces the current tire and wheel assembly. There is no need for complex mounting equipment and once they are bolted on, there is no air pressure to maintain The unique energy transfer within the poly-resin spokes helps reduce the “bounce” associated with pneumatic tires, while providing outstanding handling characteristics. The MICHELIN X TWEEL Turf airless radial tire is a single-unit assembly that replaces a conventional tire and wheel, eliminating the need for air pressure entirely — which means no flats, no downtime, and no patch kits. The wear life of a TWEEL tire is significantly longer than a comparable pneumatic tire, reducing the frequency of replacement and total cost of ownership over time. Verify your model and serial number to confirm the correct size before ordering.

48 inch Recycler Kit (GrandStand) (Part # 139-6650)
This genuine Toro OEM 48-inch Recycler kit is designed for Toro GrandStand stand-on mowers and converts the deck to full Recycler mulching operation. Once installed, the patented Recycler system cuts clippings 6 to 8 times and returns them to the lawn as fine, nutrient-rich natural fertilizer — eliminating the need to bag or rake in most conditions. One of the most popular purchase-stage upgrades for new GrandStand owners who want to maximize the value of their machine from day one. Verify your model and serial number before ordering.

Genuine OEM Part 140-1243
16.5 Inch Hi-Flow Blade (Part # 140-1243)
This Toro OEM 16.5-inch Hi-Flow replacement mower blade is designed to produce high lift, cutting grass cleanly and propelling clippings upward and out through the discharge chute. Hi-Flow blades — also referred to as basic, standard, or 2-in-1 blades — are the preferred choice when using a grass catcher or bagger, as the increased airflow drives clippings efficiently into the collection bag. This blade is compatible with multiple Toro riding lawn mowers models — always verify your model and serial number before ordering to confirm the correct fit.
$31.49 USD
Genuine OEM Part 140-4860
16.5 Inch Medium Flow Blade (Part # 140-4860)
This Toro OEM 16.5-inch Mid Flow replacement mower blade is engineered to provide a balance between the high suction of Hi-Flow blades and the minimal airflow of Low Flow blades. Mid Flow blades have a slight upward angle on the cutting edges, producing moderate lift while requiring less horsepower than Hi-Flow blades — making them a versatile option for varied terrain and grass conditions. Compatible with multiple Toro riding lawn mowers models — verify your model and serial number before ordering.
$30.44 USD
Genuine OEM Part 140-4861
16.5 Inch Low Flow Blade (Part # 140-4861)
This Toro OEM 16.5-inch Low Flow replacement mower blade features a slightly curved tip design that keeps airflow to a minimum during operation. Low Flow blades are the right choice for mowing in sandy, dusty, or dry conditions where high suction would stir up excessive debris — they also cause less strain on the engine than Hi-Flow blades, making them a practical option when horsepower is a consideration. Compatible with multiple Toro riding lawn mowers models — verify your model and serial number before ordering.
$32.54 USD
Genuine OEM Part 140-4862
16.5 Inch Atomic Blade (Part # 140-4862)
This Toro OEM 16.5-inch Atomic replacement blade — commonly known as a Gator-style blade — features a serrated cutting edge with raised teeth that shred grass clippings into much finer pieces than a standard mulching blade. The serrated design re-cuts clippings multiple times on every pass, delivering the highest mulching quality available and a consistently crisp, clean cut even in dense or damp grass. Compatible with multiple Toro riding lawn mowers models — verify your model and serial number before ordering.
$34.64 USD
Genuine OEM Part 140-4863
16.5 Inch Recycler Blade (Part # 140-4863)
This Toro OEM 16.5-inch Recycler replacement mower blade is built to work within Toro's Recycler mulching system, featuring uniquely shaped 'accelerator' wings that act as a fan to keep clippings circulating beneath the deck. As clippings are forced back into the cutting zone, they are re-cut multiple times into fine pieces that fall back into the lawn and break down into natural fertilizer — feeding the grass and reducing the need to bag or rake. Compatible with multiple Toro riding lawn mowers models — verify your model and serial number before ordering.
