Walker 16" Mulcher Blade and Hub 5706-8 Fits DM48 Mower Deck OEM New.

Restore Clean Mulching Performance & Eliminate Deck Vibration: Genuine Walker Blade & Hub

Eliminate ragged turf tearing, uneven cut heights, severe deck spindle vibration, and clumped grass clippings on your commercial Walker mower. This Genuine Walker Factory OEM 16-Inch Mulcher Blade & Hub Assembly (Part Number 5706-8) is the authentic complete blade and drive hub replacement engineered explicitly for select Walker DM48 48-inch mulching deck models . Operating a Walker front-mount deck with a bent blade or cracked hub puts dangerous stress on the internal deck gearboxes and spindle bearings, leading to costly drive system failure.

Manufactured in the USA to Walker's exacting commercial standards, the 5706-8 assembly features a heat-treated, high-carbon alloy steel mulching blade factory-mated to a heavy-duty, precision-machined drive hub. The specialized mulching profile features aggressive lift and cutting wings designed to keep clippings suspended inside the DM48 baffled deck chamber until they are pulverized into fine, quick-decomposing mulch. Precision dynamically balanced at the factory, this integrated blade-and-hub unit bolts directly onto your deck spindle without wobble, ensuring even wear across the cutting width and maintaining Walker’s signature striping finish.

This authentic factory replacement component is cataloged under Walker OEM Part Number 5706-8 (57068 / Blade & Hub Asm 16" Mulch / DM48 Mulcher Blade / Commercial Walker Blade) . (Note: Specifically engineered for select Walker DM48 deck models—verify your deck serial number and hub style prior to ordering).

🛠️ Pro-Maintenance Tip: Watch the "Hub Seating Check & Deck Leveling Secret!" Hub Seating & Torque Secret: When mounting the new 5706-8 blade and hub assembly onto the deck spindle, make sure the mating spindle shaft and flange are completely free of dried grass, rust, and dirt buildup. Any grit trapped between the spindle face and hub will cock the blade at an angle, causing vibration and an uneven cut. Hand-thread the mounting hardware and torque to Walker's exact factory specification (typically 55–60 ft-lbs ). Deck Chamber Cleanout Secret: For the mulching wings to work effectively, the underside of the DM48 deck must remain free of caked, decomposing grass buildup. When swapping blades, scrape the interior baffles clean. A smooth, clean deck baffle allows high-velocity circular airflow to continuously cycle clippings across the cutting edges rather than dropping clumps onto the turf.
