What It Is

This is a 2-pack of spindle assemblies (part 130794) with pulleys (153535) and a drive belt (174883) designed to replace the cutting deck spindles on Husqvarna lawn tractors like the YTH18542 and YTH1542. It’s used for mowing decks that require two or three spindles to spin the blades.

Fitment & Compatibility

• Check your deck size: Fits 42-inch and 46-inch decks on Husqvarna and some compatible brands (e.g., Poulan, Craftsman). Measure blade bolt spacing or deck model number to confirm.
• OEM cross-reference: Replaces OEM part numbers 128774, 137645, 174883, 532128774, 532130794, 532137645, 532137646, 532174883, and 539110158. This is an aftermarket set, not genuine Husqvarna.
• Measurements: Spindle shaft diameter is 5/8-inch; pulley diameter is 4.5 inches. Verify your existing spindle and pulley match these specs.
• Model compatibility: Direct fit for Husqvarna YTH18542 and YTH1542, but also works on many other models with the same deck—check your owner’s manual or deck part number.

Key Things to Know

• Quality note: Aftermarket spindles are generally fine for residential use, but may have slightly shorter bearing life than OEM. Inspect bearings for smooth rotation before install.
• Installation difficulty: Moderate—requires removing deck, unbolting old spindles, and transferring pulleys. You’ll need basic tools (ratchet, socket set, maybe a puller for stuck pulleys).
• Common gotcha: The belt (174883) is included, but verify it matches your deck’s belt routing diagram. Some decks use a different belt length; measure your old belt if possible.
• Double-check pulley fit: The pulley is a separate piece—ensure the spindle shaft keyway and pulley hub align. If your old pulley is worn, replace it with the included one.

Should You Buy It

If you need to replace one or two spindles on a Husqvarna 42-inch or similar deck and want a cost-effective kit with a belt and pulleys included, this is a solid choice for residential mowing. Avoid if you require OEM parts for heavy commercial use or if your deck uses non-standard spindle dimensions.
