46 inch Mower Deck Rebuild Kit for MTD White Huskee Yard Machines LT946G LT546G 4600H, for Toro LX460, LX465, LX466, Spindle 112-0311 112-0383, Blade 112-0304 112-0302, 1/2" x 79" Belt 112-0317

What It Is

This 46-inch mower deck rebuild kit includes replacement spindles, blades, and a drive belt for MTD-built tractors (White, Huskee, Yard Machines) and compatible Toro LX models. It’s designed for a full deck overhaul—replacing worn spindles, dull blades, and a stretched belt in one purchase.

Fitment & Compatibility

Before buying, confirm your mower has a 46-inch stamped steel deck (not fabricated). This kit fits MTD models LT946G, LT546G, and 4600H, plus Toro LX460, LX465, and LX466. The spindles are OEM replacements for 112-0311 and 112-0383; blades replace 112-0304 and 112-0302 (both 1/2-inch center hole, 16.5-inch length). The belt is 1/2-inch wide by 79 inches long (part 112-0317). Measure your current belt length and spindle housing diameter (typically 4 inches) to verify. Not compatible with 42-inch or 54-inch decks.

Key Things to Know

• Quality: Spindles are aftermarket, not OEM MTD—may vary in bearing durability. Blades are standard-grade steel, fine for residential use but not commercial.
• Installation difficulty: Moderate. You’ll need a socket set, jack or lift, and patience to remove old spindles (often rusted). Expect 1–2 hours.
• Common gotcha: The belt routing diagram is not included; note the path before removal. Use a smartphone photo.
• Deck removal required: You must remove the deck to replace spindles—can’t do it on the mower.

Should You Buy It

Buy this kit if your 46-inch MTD or Toro LX deck has noisy spindles, dull blades, and a slipping belt, and you want a single-box solution for a full refresh. It’s a cost-effective alternative to buying parts separately, but skip it if you need OEM spindles for heavy commercial use—aftermarket bearings may fail sooner.
