48" 44" Deck Mower Blades Fit for Ariens Max-Zoom 48HD Gravely ZT 48 HD Pro-Turn 48 Zero Turn Lawn Mower Replaces OEM 00450200 (High-Lift) 3 Pack

What It Is

This is a 3-pack of high-lift replacement blades designed for 48-inch and 44-inch zero-turn mower decks, specifically Ariens Max-Zoom and Gravely Pro-Turn models. High-lift blades create extra airflow for improved grass clipping discharge, making them ideal for bagging or side-discharge use on thick or tall grass.

Fitment & Compatibility

Must check before buying:

• Deck size: Only fits 48" or 44" decks (verify your deck measures exactly 48" or 44" blade tip-to-tip). Not for 42", 52", or 60" decks.
• Model compatibility: Ariens Max-Zoom 48HD, Gravely ZT 48 HD, and Gravely Pro-Turn 48. Double-check your mower’s model number—some “48” models may use different blade patterns.
• OEM vs aftermarket: Replaces OEM part #00450200. Aftermarket blades may have slightly different balance or thickness compared to genuine Ariens/Gravely parts.
• Blade dimensions: Length should be 21.5" (center hole to tip), with a 1" center hole and 0.625" (5/8") spindle diameter. Measure your current blade to confirm.
• Mounting holes: Verify the offset and hole pattern match your spindle—some models use a 3-point or oval pattern.

Key Things to Know

• High-lift design increases suction but also increases engine load and wear on belts/spindles. Not recommended for dry, sandy conditions or if you prefer mulching.
• Installation difficulty: Moderate. You’ll need a torque wrench (tighten to 70-90 ft-lbs), a blade removal tool, and thread locker on the spindle bolts. Always lift the deck and block it safely.
• Balance check: Aftermarket blades often need balancing. Use a cone balancer to avoid vibration that can damage spindles or the deck.
• Common gotcha: These blades are not “universal”—they will not fit most residential zero-turn mowers (e.g., Husqvarna, John Deere). Only for Ariens/Gravely commercial-grade decks.

Should You Buy It

If you own an Ariens Max-Zoom 48HD or Gravely ZT/Pro-Turn 48 and need high-lift blades for bagging or heavy discharge, this 3-pack is a solid budget-friendly alternative to OEM. But skip if you mulch, cut dry grass, or want the exact fit and durability of genuine parts.
