What It Is

This is a replacement mower spindle assembly (mandrel) that drives the blade on a zero-turn or lawn tractor deck. Designed for 42", 46", 48", and 54" decks on Craftsman, Husqvarna, Ariens, Poulan Pro, and similar brands.

Fitment & Compatibility

• Deck size: Fits 42", 46", 48", and 54" decks—but verify your deck’s spindle hole spacing (center-to-center of mounting bolts). Common pattern is 3.5" or 4".
• OEM cross-references: Replaces 187292, 192870, 532187281, 532187292, 567253301. If your original part number matches one of these, it’s a direct swap.
• Brands: Direct fit for Craftsman (LT, GT, ZT models), Husqvarna, Ariens, Poulan Pro, and some AYP/Electrolux-built decks. Not universal—check your deck’s brand and model number.
• Measurements: Shaft diameter is 5/8" (standard for most residential blades). Overall height is about 4.5". Confirm your blade bolt pattern (5/8" center hole) and spindle housing depth before buying.

Key Things to Know

• Quality vs. OEM: This is an aftermarket part at a budget price. It’s functional but may have slightly looser tolerances or less durable bearings than OEM. Expect 1-2 seasons of residential use.
• Installation difficulty: Moderate. You’ll need a socket set, torque wrench (tighten to 30-40 ft-lbs), and possibly a puller if the old spindle is seized. Disconnect the spark plug first.
• Common gotchas: The grease fitting (Zerk) is present, but some users report it’s hard to access once installed. Grease it before mounting. Also, the mounting holes may need slight filing if alignment is off.
• Bearing noise: A small number of units arrive with dry or gritty bearings. Spin the spindle by hand before installing—if it feels rough or noisy, return it.

Should You Buy It

This is a solid pick if you need a quick, affordable replacement for a worn spindle on a residential mower, especially if your original part number matches. Skip it for heavy commercial use or if you want OEM-grade longevity—spend more on a genuine or heavy-duty aftermarket spindle instead.
