8TEN Deck Belt Blade Spindle Kit for Ariens Husqvarna Poulan 2246LS 2346XLS YTA1946 532403107 21548042 532187281

What It Is

This is a complete deck belt and blade spindle assembly kit for residential riding mowers, designed to replace worn spindles and belts that cause uneven cutting or blade vibration. It’s intended for Ariens, Husqvarna, and Poulan models with 46-inch decks.

Fitment & Compatibility

Before buying, confirm your mower’s deck size is exactly 46 inches (measured blade tip to tip). This kit fits specific models including Ariens 2246LS, 2346XLS, and Poulan YTA1946—but not all 46-inch decks are identical. Check your OEM part numbers: 532403107 (belt), 21548042 (spindle), and 532187281 (spindle assembly). If your current spindles have different numbers, measure spindle bolt hole pattern (typically 3-bolt, 3-inch spacing) and belt length (approx. 96.5 inches). This kit replaces two spindles and one belt; verify your deck uses two spindles (not three).

Key Things to Know

• Quality: 8TEN is an aftermarket brand; spindles are steel with sealed bearings, comparable to OEM, but belt may be slightly thinner than genuine Husqvarna. Inspect belt fitment tension after install.
• Installation: Moderate difficulty—requires removing deck, unbolting old spindles (often rusted), and re-torquing new ones to 30-35 ft-lbs. Have penetrating oil and a breaker bar ready.
• Gotcha: The kit includes two spindles but only one belt—if your deck uses a second belt for a separate blade drive, you’ll need to order it separately. Also, check pulley diameter (4.5 inches) matches your original to avoid blade speed issues.
• Common issue: Spindle bolts may use a 5/8-inch hex head; ensure your socket fits. If your deck has a different spindle height, the blades may hit the deck shell—measure old spindle height (approx. 3.5 inches from mounting flange to pulley bottom).

Should You Buy It

This kit is a solid value for DIY riders who need a complete spindle and belt replacement on common 46-inch Ariens, Husqvarna, or Poulan models, especially if you’re already replacing spindles and want a matched belt. It’s not for commercial use or oddball decks—stick with OEM if you have a non-standard spindle pattern or need exact belt durability.
