Lawn Mower Spindle Assembly,Height：5-7/8''(150mm), Replace AYP 174356 174358 Husqvarna z246 532174356 587125201 532174358 GTH2548 GT2248 GTH2248 YTH1848XP YTH2448 YTH2748

What It Is

This spindle assembly transfers power from the deck belt to spin your mower blade. It’s a direct-fit replacement for Husqvarna and AYP (American Yard Products) mowers with 42–54-inch decks, including select Z246 zero-turns and GT/YTH garden tractors.

Fitment & Compatibility

Before buying, confirm three things:

• Deck size & model: Fits 42–54-inch decks on Husqvarna Z246, GTH2548, GT2248, GTH2248, YTH1848XP, YTH2448, YTH2748. Also fits AYP/Seat equivalents like GT2248, YTH2448.
• Height: 5-7/8 inches (150mm) – measure your existing spindle from mounting base to blade-mount surface. If yours is taller or shorter, this won’t work.
• OEM part cross-reference: Replaces Husqvarna 532174356, 532174358, 587125201, and AYP 174356, 174358. If your mower uses a different spindle part number, check mounting hole pattern (usually 3-bolt, 4-inch spacing) and shaft diameter (typically 5/8-inch with keyway).

Key Things to Know

• Quality: Aftermarket unit at a budget price. Bearings are sealed but not heavy-duty; expect 2–3 seasons of residential use. Commercial mowing may need OEM or premium spindles.
• Installation: Moderate difficulty (30–60 minutes). Requires removing deck, belt, blade, and pulley. Use a puller if the old spindle is seized. Torque blade bolt to 40–50 ft-lbs.
• Common gotcha: The included grease fitting is plastic – swap to a metal Zerk if you grease regularly. Also, check pulley alignment after install; shims may be needed to prevent belt wear.
• Bearing failure signs: Wobble, noise, or blade scraping deck. Replace both spindles at once if one fails to avoid uneven wear.

Should You Buy It

If you have a compatible Husqvarna or AYP mower with a 42–54-inch deck and need an affordable replacement for residential mowing, this spindle does the job. For heavy commercial use or if you want OEM-grade durability, spend more on a genuine Husqvarna unit.
