UDC Parts 09081200 High Lift Blades Replacement for Gravely 60 Inch 03253900 Ariens Apex 60" Max Zoom Zenith 09246600 Pro-Master PM 160M 260Z 160Z 260M ZT60HD Pro-Turn 160 260 360 460 560 660/3 Pack

What It Is

A 3-pack of high-lift replacement blades for 60-inch zero-turn mowers, designed to increase airflow for superior grass clipping discharge and bagging performance, especially in thick or wet grass.

Fitment & Compatibility

Before buying, verify your mower has a 60-inch cutting deck and uses the Gravely 03253900 or Ariens 09246600 OEM blade pattern. These blades fit Gravely Pro-Turn 160/260/360/460/560/660, Pro-Master PM 160M/260Z/160Z/260M, and Ariens Apex 60", Max Zoom, Zenith, and ZT60HD models. Measure your existing blade length (should be 20.5 inches), center hole diameter (typically 1 inch), and thickness (0.25 inches). The blade offset and lift angle must match your deck’s spindle and discharge chute clearance—check by comparing the blade’s airlift curve to your old one. Not compatible with non-60-inch decks or models using different mounting patterns.

Key Things to Know

• High lift vs. standard: These blades create more suction, improving bagging and side discharge, but they increase engine load and may reduce runtime on battery models. Not ideal for mulching unless paired with a mulch kit.
• Installation: Requires a socket wrench and torque wrench (set to 70-90 ft-lbs). Use thread-locker on spindle bolts to prevent loosening. Always lift the deck and block it securely before working.
• Quality concerns: Some users report slight imbalance out of the box—check by spinning the blade on a nail or balancer. UDC blades are heat-treated steel but slightly thinner than OEM, so they may wear faster in abrasive conditions.
• Deck clearance: High-lift blades can hit the deck shell if your deck is warped or if you install them upside down. Confirm the blade’s lift angle points upward toward the deck.

Should You Buy It

If you need strong bagging or side discharge performance on a 60-inch Gravely or Ariens zero-turn and want to save over OEM pricing, this is a solid choice. Skip it if you primarily mulch or run a deck smaller than 60 inches—standard or low-lift blades will suit you better.
