5101755S Mower Blades 61 in Replacement - Heavy Duty Cut

In this review the 5101755S mower blades are examined for owners of commercial and residential 61 in decks who need a straightforward replacement blade. The bottom line: these blades are a heavy duty, laser-cut steel option that fit Ferris, Bad Boy and Scag 61 in decks and offer a sharp cutting edge and good fit out of the box, making them a practical buy for users who want an inexpensive, durable replacement and a vendor who stands behind an after-sales replacement guarantee.

Key Features

• Exact fit: Designed to replace common 61 in blades such as 5101755 and 5020842S, so mounting is direct and fast without modification.
• Durable construction: Made from high quality steel to resist moisture and corrosion for longer service life in outdoor use.
• Laser-cut edge: The factory laser cutting produces a thin, sharp cutting section that improves grass clean cut and reduces tearing.
• Solid dimensions: Each blade measures 21 in long with a 5/8 in center hole and 0.16 in thickness, matching typical 61 in mower center spindles.
• After-sales guarantee: The seller offers post-return period support and will replace blades if there is an issue, which reduces risk for buyers.
• Versatile compatibility: Works with Ferris, Bad Boy and Scag 61 in decks, covering a broad range of commercial and premium residential mowers.

Who It's For

This blade is best for homeowners with large properties, groundskeepers and small landscaping businesses running 61 in zero-turn or deck mowers who need a reliable replacement that installs without fuss. The solid steel construction and laser-cut edge suit frequent mowing cycles and mixed turf conditions where a clean cut is important for turf health.

Those who need a specialty offset blade, a different hole pattern, or a blade guaranteed to retain a razor edge for extremely long intervals should consider other premium or hardened-edge options, because a few customers reported variable edge life and occasional dull blades on arrival.
