585318201 584807501 Fuel Tank for Husqvarna P-ZT48 PZT60 Lawn Mower, Fits MZ 48 52 54 61 M-ZT52 M-ZT61 model

What It Is

This is a replacement fuel tank assembly for Husqvarna zero-turn mowers, designed to store and supply fuel to the engine. It’s intended for commercial-duty mowers like the P-ZT48 and PZT60, as well as several MZ and M-ZT models, making it a direct swap for a cracked, leaking, or degraded original tank.

Fitment & Compatibility

• Exact OEM numbers: 585318201 and 584807501. This is a genuine Husqvarna part, not an aftermarket generic.
• Confirmed models: Husqvarna P-ZT48, PZT60, MZ 48, MZ 52, MZ 54, MZ 61, M-ZT52, M-ZT61. Also fits some earlier Z-series and certain Craftsman/Electrolux variants using the same chassis.
• Deck size check: Works with 48”, 52”, 54”, and 61” decks, but only on zero-turn platforms. Not for walk-behinds or tractors.
• Measurements: Tank is roughly 18” x 10” x 6”. Measure your existing tank’s mounting holes and filler neck position to confirm alignment—especially if your mower is older or has been modified.
• What to verify before buying: Look under the seat or near the fuel cap for your model and serial number. Cross-reference with Husqvarna’s online parts diagram. If your current tank has a different outlet port angle (straight vs. 90-degree), you may need a separate fuel line kit.

Key Things to Know

• Build quality: OEM plastic, same as original. UV-stable and resists cracking from ethanol fuels, but still brittle if over-tightened or dropped.
• Installation: Easy—remove the old tank (drain fuel first), transfer the fuel cap and shutoff valve, then bolt in the new one. No special tools needed. Allow 20-40 minutes.
• Common gotchas: The tank doesn’t include a fuel cap or shutoff valve—reuse your old ones or buy separately. Also, the filler neck gasket may be thin; use thread sealant if it leaks.
• Return policy: Check seller’s return window. Some sellers charge restocking fees for opened fuel tanks.

Should You Buy It

If your Husqvarna zero-turn has a leaking or warped fuel tank and you want a direct OEM replacement without measuring aftermarket parts, this is the right pick. It’s affordable, fits most 48”-61” models, and installs quickly. Avoid if you need a cap or valve included, or if your mower is a different brand.
