Husqvarna Depth Gauge 0.404" (H64) 5056981-02

What It Is

The Husqvarna Depth Gauge 0.404" (H64) 5056981-02 is a replacement gauge wheel bracket for zero-turn mowers, used to set and maintain consistent cutting height. It’s designed specifically for commercial-grade Husqvarna mower decks with a 0.404" wheel shaft diameter.

Fitment & Compatibility

• Check your deck model: This part fits Husqvarna Z200, Z400, Z500, and PZ500 series zero-turn mowers (e.g., Z242F, Z254, Z560). Also fits some AYP/Garden Way models.
• Measure your wheel shaft: The gauge accepts a 0.404" (approx. 10.3 mm) diameter wheel axle. If your wheel shaft is 0.500" or 5/8", this won’t work.
• OEM vs aftermarket: This is a genuine Husqvarna OEM part (part #5056981-02). Aftermarket alternatives exist but may have looser tolerances or different bracket geometry.
• Deck size: Compatible with 48", 54", and 60" decks that use the H64 gauge system. Not for push mowers or residential stamped decks.

Key Things to Know

• Installation is straightforward – removes with a single bolt (usually 3/8" or 7/16" wrench). No special tools needed.
• Adjustable height range – typically 1.5" to 4.5" in 0.5" increments, depending on your deck’s linkage.
• Common gotcha: The plastic wheel on this gauge can wear or crack over time, especially if you mow over rough terrain. Check the wheel condition before buying.
• Weight rating: Designed for decks up to ~250 lbs. Heavier commercial decks may require the heavy-duty version (part #5056981-01).

Should You Buy It

Buy this if your Husqvarna zero-turn’s original gauge wheel is broken, bent, or missing, and your wheel shaft measures exactly 0.404". It’s a direct OEM replacement that restores consistent cutting height and prevents scalping. Skip it if you need a 0.500" or 5/8" shaft gauge, or if you’re on a tight budget and willing to try a generic alternative.
