What It Is

This ACEBRI deck rebuild kit bundles the essential wear items for a 46-inch Husqvarna cutting deck: two spindles, two pulleys, two blades, a belt, and rebuild hardware. It’s designed for a complete one-and-done refresh on older Husqvarna lawn tractors with fabricated or stamped 46-inch decks.

Fitment & Compatibility

Double-check your model number. This kit fits Husqvarna YTA1946, YTA22V46, YTH20K46, YTH2246TDR, 2246LS, and 2346XLS tractors—all with a 46-inch deck. It replaces OEM parts: spindle assembly 192870, rebuild kit 587253301, blade 405380, and belt 197473. Before buying, measure your existing belt length (should be roughly 95 inches) and verify your deck’s blade bolt pattern (typically 3-point, 2-3/8 inch center hole). The pulleys are 4-inch OD with a 5/8-inch bore. If your deck uses different spindle bearings or a 7/8-inch arbor, this kit won’t fit.

Key Things to Do

• Inspect your deck shell. Worn-out spindles often damage the housing. If the mounting holes are wallowed out or cracked, new spindles may not sit tight. Replace the deck if rusted through.
• Torque the spindle bolts. Use a torque wrench to 30–40 ft-lb. Over-tightening can warp the bearing housing; under-tightening causes wobble and premature failure.
• Check blade orientation. The 405380 blades are stamped steel, 18.5 inches long, and have a specific lift curve. Install with the cutting edge facing the direction of rotation (usually counterclockwise when viewed from above).
• Belt routing matters. Note the original belt path before removing. The 197473 belt drives both spindles from the engine pulley; misrouting causes poor engagement or belt throw.

Should You Buy It

If your 46-inch Husqvarna deck has noisy spindles, dull blades, or a slipping belt, this kit is a solid value for a full refresh. It’s best for DIY owners who want to replace all wear parts at once rather than chasing individual failures. With only one review (5 stars), you’re buying on spec—the components match OEM dimensions, but the spindle bearings and blade steel may not last as long as genuine Husqvarna parts. For a weekend warrior with a 5–10 year old tractor, it’s a cost-effective fix. For heavy commercial use, stick with OEM.
