Hypr-oil™ 500 (quart). Toro Hypr-Oil 500 is a high-performance hydraulic fluid specifically formulated and approved by Toro engineering for use in Toro commercial zero turn mowers. It provides excellent wear and corrosion protection for hydraulic systems, helping to maintain consistent performance and extend the service life of hydraulic components. Always refer to your operator manual for the correct fluid specification and service intervals.

Riding Mower Jack Kit (Part # 127-6666)
This genuine Toro OEM riding mower jack kit is designed to safely lift and support your Toro riding mower or zero turn, giving you safe, stable under-deck access for blade changes, belt replacements, and routine maintenance. It is one of the most practical purchase-stage accessories for any new mower owner — investing in a proper jack from day one avoids improvised lifting methods that risk injury and equipment damage. Verify your model and serial number before ordering.
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.
