High-Lift Blade Design
The 491-530 uses a high-lift blade profile designed to create increased airflow underneath the mower deck. The raised blade wings help lift grass before cutting and move the resulting clippings toward the mower's discharge area.
This design is particularly useful for:
- Side discharge
- Bagging
- Maintaining strong airflow under the deck
- Moving grass clippings efficiently
- Producing consistent cutting results
Oregon states that the aggressive blade angle increases airflow to push debris upward and outward for improved bagging and side-discharge performance.
Important Notes
- Verify compatibility with your exact Dixon mower model, deck size, spindle configuration, and original blade part number before ordering.
- Oregon identifies 491-530 as a mower blade compatible with the Dixon Fusion Series.
- Although commonly described as a 15-inch blade, Oregon specifies the actual blade length as 14-15/16 inches.
- The blade measures 2-1/2 inches wide and .203 inches thick.
- The specified center hole is 11/16 inch.
- The specified air lift is 1-1/4 inches (31.75 mm).
- Applicable 44-inch Dixon decks require three 491-530 blades for a complete blade set.
- This listing is for one blade, unless a multi-blade quantity is explicitly specified.
- If replacing all blades on an applicable 44-inch deck, order the quantity required for your mower.
- For best cutting performance, blades installed on the same deck should be in comparable condition and properly balanced.
- Do not select a mower blade based solely on approximate overall length.
- Confirm the center-hole size, width, thickness, length, blade profile, and OEM cross-reference before installation.
- Inspect the spindle, blade adapter, mounting bolt, washers, bearings, and surrounding mower deck components when replacing a damaged blade.
- Never reuse a blade that is cracked, severely bent, structurally damaged, or excessively worn.
- If an existing blade was damaged by striking an object, inspect the spindle and associated deck components for corresponding damage.
- Install the blade in the correct cutting orientation according to the mower manufacturer's instructions.
- Make sure the blade is properly seated against the applicable spindle or adapter.
- Tighten blade mounting hardware to the equipment manufacturer's specified torque.
- An improperly installed or unbalanced blade can cause excessive vibration, poor cutting performance, or damage to mower components.
- Shut off the mower, remove the ignition key, disconnect the spark plug or battery where applicable, and wait for all moving components to stop before servicing the cutting deck.
- Wear appropriate protective gloves when handling mower blades.
- This listing is for one Oregon 491-530 15-Inch Dixon Fusion Blade only unless otherwise specified. Spindles, blade bolts, washers, adapters, belts, and other mower deck components are sold separately.
- Match Oregon part number 491-530 or one of its supported Dixon OEM cross-references with your equipment documentation before ordering to ensure proper fitment.
