Ariens 3PK Genuine OEM Gravely 00450200 48" 44" Zero Turn Lawn Mower Blades

What It Is

This is a set of three genuine OEM mower blades (part #00450200) designed for Ariens and Gravely zero-turn mowers with 44-inch or 48-inch cutting decks. They are built for residential and light commercial use, providing a clean cut for standard grass conditions.

Fitment & Compatibility

• Deck size: Fits 44" and 48" Ariens/Gravely zero-turn decks only. Not for 42", 52", 54", or 60" decks.
• Model check: Compatible with Ariens Zoom and Gravely ZT/ZT HD series (e.g., Zoom 1540, ZT HD 48, ZT X 48). Verify your model number on the deck or owner’s manual.
• OEM vs aftermarket: These are genuine Ariens parts, so fitment is guaranteed for listed models. Aftermarket blades may have different hole patterns or thickness.
• Measurements: Each blade is approximately 16.125 inches long, 2.5 inches wide, with a 5-point star center hole and 0.5-inch center hole diameter. Measure your old blade length and hole pattern to confirm.
• What to check: Look for a model number sticker on the underside of your deck near the blade spindles. If you have a 44" or 48" deck, these blades should work.

Key Things to Buy

• Quality: OEM blades are heat-treated and balanced for durability. They hold an edge longer than many aftermarket options, reducing the need for frequent sharpening.
• Installation difficulty: Moderate. You’ll need a socket wrench and a blade removal tool (or a block of wood to prevent spinning). Torque blades to 40-50 ft-lbs for safety.
• Common gotcha: Don’t assume all 48" decks use the same blade. Some Ariens/Gravely models with a 48" deck require a different blade (e.g., part #00450100 for 42" decks). Double-check your part number.
• Set includes: Three blades, but no hardware (bolts/washers). Use your existing hardware unless it’s worn.

Should You Buy It

Yes, if you own an Ariens Zoom or Gravely ZT HD/ZT X with a 44" or 48" deck and want a reliable, factory-fit blade that cuts cleanly and lasts. The $50 price is reasonable for OEM quality, and the 4.7-star rating reflects consistent performance. Skip if you need blades for a different brand or deck size, or if you prefer a cheaper aftermarket option for occasional use.
