KOOTANS 2 Pack Mower Spindle Assembly for AYP 174356 174358 Husqvarna 532174356 587125201 532174358 Z246 GTH2548 GT2248 GTH2248 YTH1848XP YTH2448 YTH2748, Fits AYP 48" Decks 2002 (with Bolts, Zerk)

What It Is

This is a 2-pack of mower spindle assemblies designed to replace the original equipment on AYP (American Yard Products) and Husqvarna 48-inch cutting decks from around 2002 onward. Each spindle holds and spins the mower blade, and these are direct replacements for the OEM part numbers listed.

Fitment & Compatibility

Before buying, confirm your mower deck is a 48-inch AYP or Husqvarna model from 2002 or later. This kit fits popular tractors like the Husqvarna GTH2548, YTH1848XP, YTH2448, and YTH2748, as well as AYP models Z246, GTH2248, and GT2248. It replaces OEM numbers 174356, 174358, 532174356, 532174358, and 587125201. Measure the spindle shaft diameter (should be 5/8-inch) and the bolt pattern (typically 3-bolt, 4-inch center-to-center). Verify your deck’s pulley and blade mounting holes match—these spindles use a standard 5/8-inch hex shaft and accept a standard 3-hole blade pattern. If your deck is 42-inch or 54-inch, or from a different brand, this will not fit.

Key Things to Know

• Includes hardware – Kit comes with mounting bolts and a Zerk fitting (greaseable spindle), so you don’t need to buy extra fasteners. Grease the Zerk fitting before first use.
• Installation difficulty – Moderate. You’ll need basic hand tools (wrenches, socket set) and a jack or blocks to lift the mower. Expect 30–60 minutes per spindle.
• Common gotcha – The pulley retaining bolt torque is critical (typically 30–40 ft-lbs). Over-tightening can strip the spindle threads; under-tightening can cause wobble. Check your deck’s pulley alignment after installation to avoid belt wear.
• Aftermarket quality – These are non-OEM replacements. They should work fine for residential use, but if you mow commercially or on rough terrain, OEM spindles may last longer.

Should You Buy It

If you have a 48-inch AYP or Husqvarna tractor deck from the 2000s and need a budget-friendly, ready-to-install replacement spindle set, this is a solid choice. The included hardware and grease fitting simplify the job, and the price is competitive for a 2-pack. For heavy commercial use or older decks (pre-2002), consider OEM spindles for better durability.
