8TEN Deck Belt Blade Spindle Pulley Kit for Ariens Husqvarna Poulan 2246LS 2346XLS YTA1946 532405380 21546611 532187281

What It Is

This is a complete deck belt and blade spindle pulley kit designed to replace the factory pulleys and belt on select Ariens, Husqvarna, and Poulan lawn tractors. It’s intended for machines with a 46-inch cutting deck, typically used for residential mowing of medium-to-large lawns.

Fitment & Compatibility

Before buying, verify these three things:

• Deck size: This kit fits 46-inch decks only. Measure your deck width to confirm.
• Model numbers: Compatible with Ariens 2246LS, 2346XLS; Husqvarna YTA1946; Poulan Pro PP46T; and others using OEM part numbers 532405380, 21546611, and 532187281. Check your mower’s manual or current part numbers.
• Pulley dimensions: The kit includes two 4-inch OD spindle pulleys and one 3.5-inch OD idler pulley. If your deck uses different sizes (e.g., 5-inch spindles), this won’t fit.
• Belt length: The included belt is 1/2-inch wide by 96.5 inches long. Measure your old belt or confirm deck belt length in your manual.

Key Things to Know

• Quality: The pulleys are steel with sealed bearings—better than some OEM plastic pulleys. The belt is aramid-reinforced, which resists stretching better than standard rubber belts.
• Installation difficulty: Moderate. You’ll need a socket set and a puller for the old pulleys (they’re often rusted on). Plan 45–60 minutes.
• Common gotcha: The spindle pulley bolts are reverse-thread on some models (left-hand thread). Check yours before cranking—turning the wrong way can snap bolts.
• Warranty: 8TEN offers a 1-year warranty. Some users report premature belt wear if deck alignment is off; double-check pulley alignment after installation.

Should You Buy It

Yes, if you have a compatible 46-inch deck and your current pulleys are wobbling, seized, or noisy. This kit saves you from buying each part separately and is a solid value for the price. Skip it if you need a different belt length or pulley size—or if you prefer OEM parts for warranty reasons.
