8TEN Deck Blade Belt Kit for Ariens Husqvarna 2146XLS 2246LS 2346XLS Poulan PB22H46YT 46 Inch 532405380 21546611

What It Is

This is a 3-blade belt kit for 46-inch cutting decks on select Ariens, Husqvarna, and Poulan lawn tractors. It includes the drive belt and two deck spindle belts needed to replace worn-out belts that cause blade slippage or poor cutting performance.

Fitment & Compatibility

Before buying, confirm your mower has a 46-inch deck and matches one of these models: Ariens 2146XLS, 2246LS, 2346XLS; Husqvarna 2146XLS, 2246LS, 2346XLS; Poulan PB22H46YT. The OEM part numbers are 532405380 (drive belt) and 21546611 (spindle belt). Measure your old belts—the drive belt should be roughly 1/2" x 96.5", and spindle belts 1/2" x 60.5". This is an aftermarket kit, not OEM, but uses the same specs. Verify your deck’s spindle pulley arrangement (3-blade, single belt path) matches the included belts.

Key Things to Know

• Quality: 4.8 stars from 9 reviews suggests solid durability for residential use, but don’t expect commercial-grade life.
• Installation: Moderate difficulty—requires removing the deck, routing the drive belt around pulleys and idlers, and tensioning properly. Have a manual or video handy.
• Gotcha: The kit includes two spindle belts, but some decks use one continuous belt—double-check your mower’s belt routing diagram before buying.
• Gotcha: Aftermarket belts may be slightly tighter or looser than OEM; adjust tensioner accordingly to avoid squealing or slipping.

Should You Buy It

Buy this if you have a compatible 46-inch Ariens, Husqvarna, or Poulan tractor and need a cost-effective belt replacement for regular residential mowing. It’s a good value for the price, with strong reviews, but skip it if you need OEM-certified parts for warranty or heavy commercial use.
