8TEN LawnRAZOR Blade Set for Ariens Gravely PM260Z 60 Inch Deck 09046900 (Low Lift) 3 Pack

What It Is

This is a 3-pack of low-lift mulching/standard blades designed for 60-inch Ariens and Gravely PM260Z zero-turn mowers. The low-lift profile suits dry or fine grass where less suction and reduced clumping are needed, making it a direct replacement for OEM part 09046900.

Fitment & Compatibility

• Deck size: 60 inches only; each blade is 20.5 inches long with a 1-inch center hole and 5-point star drive.
• Models: Ariens PM260Z (all variants) and Gravely PM260Z (all variants) with 60-inch fabricated deck.
• OEM cross: Replaces Ariens/Gravely part 09046900. Not compatible with 54-inch or 72-inch decks, or with stamped steel decks.
• Before buying: Confirm your mower’s deck measures exactly 60 inches and that the blade hole pattern matches (star drive, 5-point). Check your existing blade length—if it’s 20.5 inches, these fit.

Key Things to Know

• Installation: Moderate difficulty. You’ll need a torque wrench (blade bolt torque: 70–90 ft-lbs) and a blade removal tool. Star drive alignment can be finicky—ensure the blade is fully seated before tightening.
• Low-lift trade-off: Less lift than OEM high-lift blades, so they won’t throw clippings as far. Best for dry, short grass; avoid wet or tall grass where clogging may occur.
• Balance check: Out of the box, blades are balanced, but verify with a balancer after sharpening or if they feel off. Unbalanced blades cause vibration and deck damage.
• Durability: 10-gauge steel with a heat-treated edge—holds an edge reasonably well but may dull faster on sandy soil or rocks. Expect 1–2 seasons per set under normal use.

Should You Buy It

If you own an Ariens or Gravely PM260Z with a 60-inch deck and need a budget-friendly, direct-fit low-lift blade for dry conditions or light mulching, this set is a solid pick. It’s not ideal for wet grass or heavy-duty bagging, but for routine mowing on fine turf, the price and performance hit the mark.
