Husqvarna Genuine 532405507 LH 46" Mandrel Cover OEM

What It Is

This is a genuine Husqvarna OEM left-hand (LH) mandrel cover (part #532405507) that protects the spindle and belt on a 46-inch cutting deck. It’s a direct replacement for the original cover on compatible Husqvarna zero-turn and lawn tractor models.

Fitment & Compatibility

• Deck size: 46-inch (standard spacing). Measure your existing cover’s bolt pattern—this cover uses two mounting holes about 3.5 inches apart.
• Brand/model: Fits select Husqvarna zero-turn mowers (e.g., Z242F, Z254, Z4219) and lawn tractors (e.g., TS242, YTH24V48) with a 46-inch deck. Check your model’s parts diagram or serial number.
• OEM vs aftermarket: This is a genuine Husqvarna part, not a generic. Aftermarket covers may fit but often have thinner plastic or misaligned holes—stick with OEM if you want a guaranteed seal.
• What to measure: Confirm your deck has a left-hand (operator’s left) mandrel position. Measure the existing cover’s length (approx. 8 inches) and hole spacing. If your cover is cracked, warped, or missing, this is the direct swap.

Key Things to Know

• Quality: Injection-molded plastic, UV-resistant, and matches factory thickness. Holds up to debris and vibration better than cheap aftermarket versions.
• Installation difficulty: Easy (5-10 minutes). Remove two 5/16-inch bolts (likely 10mm socket), lift old cover, drop in new one, and re-torque bolts to ~10 ft-lbs. No special tools needed.
• Common gotchas: The cover is side-specific—left vs. right. This is explicitly the LH cover. If your deck has two mandrels, you’ll need a separate RH cover (part #532405508). Also, ensure the spindle pulley and belt are aligned before tightening—misalignment can cause rubbing.
• Warranty: OEM part carries Husqvarna’s 1-year warranty against defects. Keep your receipt.

Should You Buy It

If you have a Husqvarna 46-inch deck with a cracked or missing left mandrel cover, this is the correct, no-hassle fix. It’s worth the premium over aftermarket for fit and durability. Skip it if you need a right-hand cover or have a different deck size—double-check your model first.
