18 Inch Hi-Flow Blade (Part # 140-1242)
This Toro OEM 18-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.
18 Inch Medium Flow Mower Blade (Part # 140-4856)
Toro 18 Inch OEM Medium Flow blade. Medium Flow mower straight edge, standard discharge blade. These blades have slight upward angle on the edges. Great blades for use when horsepower is a concern. Produce medium Flow but requires less horsepower than Hi-Flow blades. This Toro blade has multiple applications. Be sure to verify model and serial number to ensure the correct part.
18 Inch Low Flow Mower Blade (Part # 140-4857)
This Toro OEM 18-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.
18 Inch Atomic Blade (Part # 140-4858)
This Toro OEM 18-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.
18 Inch Recycler Blade (Part # 140-4859)
This Toro OEM 18-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.
Hi-Flow 18 Inch Blade Pack (6) (Part # 140-4882)
This Toro OEM 18-inch Hi-Flow replacement mower blade — sold as a pack of 6 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.
Mid Flow 18 Inch Blade Pack (6) (Part # 140-4883)
This Toro OEM 18-inch Mid Flow replacement mower blade — sold as a pack of 6 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.
