What It Is

This is a 46-inch mower deck rebuild kit, containing the spindle assemblies, bearings, seals, and hardware needed to overhaul the deck’s rotating blade system. It’s designed for Husqvarna, Poulan Pro, and Ariens lawn tractors with 46-inch fabricated or stamped decks that use the listed OEM parts.

Fitment & Compatibility

Before buying, measure your deck’s spindle bolt pattern and blade offset. This kit fits Husqvarna models TS146X, YT46LS, YTA22V46, YTH1846, YTH20K46, YTH21K46, YTH2246, YTH22V42, YTH22V46 and Poulan Pro PP20VA46 – but only if your deck uses the 187292, 405380, 405143, or 195945 spindle assemblies. Check your owner’s manual or existing spindle housing for one of those numbers. Do not assume all 46-inch Husqvarna decks are identical – some use different spindle diameters or blade bolt patterns. This is an aftermarket kit, not OEM, so verify that the included bearings are 6204-2RS (common) and that the spindle shaft diameter matches your blades’ center hole.

Key Things to Know

• Quality concerns: With only 4 reviews and a 3.7 rating, some users report premature bearing wear or loose fit on spindle shafts. Inspect seals carefully before installation.
• Installation difficulty: Moderate – requires removing the deck, unbolting old spindles, pressing out old bearings, and pressing in new ones. A bench vise or bearing press is highly recommended.
• Common gotcha: The kit may not include new blade bolts or lock washers – reuse old ones only if they’re not stripped. Torque spindle bolts to 45–55 ft-lbs.
• Deck thickness matters: This kit is meant for standard 11–12 gauge decks; thicker fabricated decks may require different spindle spacers.

Should You Buy It

Buy this kit if you have a 46-inch Husqvarna, Poulan Pro, or Ariens lawn tractor with confirmed part numbers above, you’re comfortable with moderate mechanical work, and you want to save ~40% vs. buying OEM spindles individually. Skip it if you need guaranteed longevity for heavy commercial use, or if your deck has unusual spindle spacing or blade offset – OEM parts are safer for oddball decks.
