20.5 Inch Hi-Flow Blade (Part # 140-1240)
This Toro OEM 20.5-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.
20.5 Inch Atomic Blade (Part # 140-1241)
This Toro OEM 20.5-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.
20.50 Inch Medium Flow Blade (Part # 140-4853)
This Toro OEM 20.5-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.
20.50 Inch Low Flow Blade (Part # 140-4854)
This Toro OEM 20.5-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.
20.5 Inch Recycler Blade (Part # 140-4855)
This Toro OEM 20.5-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.
Hi-Flow20.5 Inch Blade Pack (6) (Part # 140-4877)
This Toro OEM 20.5-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.

This Toro OEM 20.5-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.
