5020843 Gator Mulching Blades for 48" Lawn Mower Deck, Compatible with Ferris 5101986 Ex-Mark 1520843 103-2527 A-riens 4919100 Bobcat 112111-01 Gravely Simplicity Snapper Mower, 3 Pack

What It Is

This is a 3-pack of Gator mulching blades designed for 48-inch lawn mower decks. They are intended for residential or commercial mowers that need fine grass clipping mulching, reducing bagging frequency and improving lawn health.

Fitment & Compatibility

Before buying, confirm your mower has a 48-inch deck (not 46" or 50"). Cross-reference your OEM part numbers: these replace Ferris 5101986, Ex-Mark 1520843, A-riens 4919100, Bobcat 112111-01, and others listed (Gravely, Simplicity, Snapper). Measure your existing blade length (should be ~18.5"–19"), center hole diameter (usually 1" or 5/8"), and lift height. Aftermarket blades may not match OEM lift or thickness exactly—check that the blade’s wing profile clears your deck’s baffles.

Key Things to Know

• Quality: Gator blades are known for good mulching performance, but some users report they dull faster than OEM or premium brands like Oregon. Expect medium longevity.
• Installation: Easy swap if you have a socket set and torque wrench. Torque to 70–90 ft-lbs (check your manual). Always use new lock washers.
• Gotcha: These are mulching blades—they will not discharge or bag well. If you need versatility, consider combo blades. Also, verify that the blade’s offset matches your deck’s spindle design (some decks require a specific “up” or “down” orientation).
• Pack: You get three blades, which is perfect for a triple-blade 48" deck—no extras to store.

Should You Buy It

Buy these if you own a 48" deck mower from Ferris, Ex-Mark, A-riens, Bobcat, Gravely, Simplicity, or Snapper and want an affordable aftermarket mulching upgrade. They’re a solid value for homeowners and light commercial use, but if you need maximum durability or OEM-specific lift, stick with the original brand or a premium aftermarket like Oregon.
