Husqvarna Deck Reinforcement (Front) OEM #589481805

The front edge of a 46″ mower deck takes a beating — every curb, tree root, landscape border, and low obstacle strikes this leading edge first. The Genuine OEM Husqvarna Deck Reinforcement (Front) #589481805 is the factory-correct steel plate that protects and structurally reinforces the front of the 46″ cutting deck, absorbing the impacts that would otherwise bend, crack, or deform the deck shell and compromise your mower’s cutting geometry and performance.

This piece helps reinforce the fragile front edge of the mower — the zone of the deck most exposed to ground-level impacts during every mowing pass. When this plate is damaged or missing, the deck’s front edge becomes vulnerable: bending inward causes uneven blade height, scalping, and vibration that worsens progressively with each use. Hitting a root or uneven ground can start to bend the original, leaving gouge marks in the lawn — the first visible sign that the front reinforcement has been compromised.

Husqvarna Part #589481805 is the Plate Reinf Deck 46″ Front Blk — an original OEM part in the Plate/Deck Plate category, specifically engineered for the 46-inch stamped steel deck. It fits Husqvarna TS 246, TS346, YT46LS, and YTA20V46 yard tractors, among other models. It also replaces earlier part numbers 581967705 and 585317705, making it the current factory-correct replacement for anyone searching those legacy numbers. Beyond Husqvarna models, it also fits other Husqvarna-produced brands that require this part, including AYP, Craftsman, Jonsered, McCulloch, Poulan, Poulan Pro, RedMax, and Weed Eater equipment.

As a genuine OEM part, #589481805 is stamped to the exact steel gauge, bolt pattern, and profile Husqvarna specifies for the 46″ deck — ensuring it seats flush, bolts securely at all mounting points, and delivers the full front-edge protection the deck was designed with.
