Description
xThese are a genuine 3-pack of Gravely/Ariens OEM mower blades designed to replace worn blades on 50" Zoom decks (fits ZT50, ZT1334 and similar models) — part number 03971900.
If your Ariens or Gravely mower isn’t cutting as cleanly as it used to, replacing the blades with the correct OEM set restores the deck’s performance and balance. This listing is for three brand-new genuine Gravely blades (Ariens-branded), made to match factory dimensions and hole patterns for a precise fit on 50-inch Zoom decks that use part numbers 03746500, 03971900, 3746500, 3971900 and 13177. Using correct-fit OEM blades helps maintain cut quality and reduces vibration compared with mismatched aftermarket shapes.
How do these blades fit my Zoom 50 or ZT50 deck?
These blades follow the original Gravely specifications for 50" Zoom decks, so they align with mounting holes and blade geometry used by the factory. Confirm your deck uses the same part number or blade mounting pattern before ordering.
- Fits 50" Zoom decks including ZT50 and compatible models
- OEM part reference: 03971900 (also cross-references 03746500, 3746500, 3971900, 13177)
- Factory-drilled mounting holes and correct blade length/shape
- Sold as a pack of three blades for full deck replacement
What material and balance qualities do these OEM Gravely blades have?
Genuine Gravely blades are stamped and heat-treated to factory hardness and edge retention standards, which helps them resist premature dulling and warping. Because they match factory weight and geometry, you’ll avoid imbalance-related vibration that can stress the spindle and deck.
- Heat-treated steel for durability and edge life
- Precision stamping for consistent weight and balance
- Edge profile tuned for mowing performance on 50" decks
- Reduces deck vibration when installed as a matched set
How should I replace and maintain these blades?
Replace blades in matched sets to keep balance and cut quality. Always disconnect the spark plug, support the mower deck safely, and follow the mower manufacturer’s torque specs for blade mounting.
- Install in matched sets of three for even balance
- Sharpen as needed; replace if bent or cracked
- Use correct mounting hardware and torque per manual
- Inspect spindles and belts when replacing blades
