8TEN LawnRAZOR Mower Blade Set for Ariens Gravely Exmark Lazer Z Zoom 1744 44 Inch 1-653102 103-2519 00272900 (Mulching)

What It Is

The 8TEN LawnRAZOR Mower Blade Set is a set of three mulching blades designed for 44-inch zero-turn mower decks, specifically for Ariens, Gravely, and Exmark models. They replace OEM part numbers 1-653102, 103-2519, and 00272900, and are intended for mulching grass clippings into fine particles to return nutrients to the lawn.

Fitment & Compatibility

Before buying, confirm your deck is exactly 44 inches (three-blade setup). These blades fit Ariens (e.g., A1744, Zoom 1744), Gravely (e.g., ZT 44, ZT HD 44), and Exmark Lazer Z or Quest models with 44-inch decks. Measure your existing blade length—these are 16.5 inches long with a 1-inch center hole and 3.0-inch diameter arbor (where the blade mounts). Verify your OEM part number matches one of the replacements listed. Not compatible with 42-inch or 48-inch decks, or with non-Ariens/Gravely/Exmark brands.

Key Things to Buy

• Quality: Made from heat-treated steel with a painted finish; users report decent durability for residential use, but may dull faster than OEM blades in heavy or sandy conditions.
• Installation: Easy swap if you have a blade removal tool and torque wrench (recommended 70-80 ft-lbs). Ensure blades are oriented with the lift wing facing up toward the deck.
• Common Gotcha: These are mulching blades—they have more lift and a curved design than standard blades. Do not use for bagging or side-discharge unless your deck has a compatible mulch kit installed.
• Balance: Some users report needing to balance blades before installation; check with a blade balancer to avoid vibration.

Should You Buy It

This set is a solid budget-friendly option for Ariens/Gravely/Exmark owners with 44-inch decks who primarily mulch and want to save over OEM prices. If you mow professionally, in heavy or wet grass, or need maximum longevity, stick with OEM or premium aftermarket blades. For residential or light commercial mulching, it’s a reliable value pick.
