What It Is

This is a complete 46-inch deck rebuild kit for select MTD, White, and Toro lawn tractors. It includes three spindles, three blades, a drive belt, and all necessary hardware to restore a worn-out cutting deck to like-new condition.

Fitment & Compatibility

• Deck size: 46 inches (must confirm your deck measures 46" blade tip to blade tip).
• Machine models: Fits MTD White GT205, LT 946G, 4600H; Toro LX 460, 465, 466. Also compatible with some Cub Cadet and Craftsman models using the same MTD platform.
• OEM part numbers: Spindles 918-0430, 112-0311, 112-0383; blades 112-0304, 112-0302; belt 112-0317 or 954-0349.
• What to measure: Verify your belt length (79 inches) and spindle bolt pattern (typically 3-bolt, 3.5" center-to-center). Measure your existing blade length (18" typical for 46" decks) and center hole diameter (usually 5/8" or 7/8").
• Aftermarket note: This is an aftermarket kit. OEM parts may have different tolerances—check that spindle bearings and blade hole sizes match your deck.

Key Things to Know

• Quality: Users report good bearing durability and blade balance, but some note the belt may be slightly stiff initially. Expect 2-3 seasons of heavy use.
• Installation difficulty: Moderate—requires removing the deck, swapping all three spindles, blades, and belt. You’ll need a jack, socket set, and torque wrench (spindle bolts: 30-40 ft-lbs; blade bolts: 50-70 ft-lbs).
• Common gotchas: The spindle mounting bolts may be seized—soak with penetrating oil. The belt routing is critical; check your deck diagram before tightening. Blade orientation: sharp edge faces forward, and the center hole must match your spindle’s pilot diameter.
• Missing parts: Some kits lack spindle dust caps or lock washers—verify you have all hardware before starting.

Should You Buy It

If your deck has wobbling spindles, dull blades, or a slipping belt, this kit is a time-and-money saver versus buying each part separately. It’s best for DIYers comfortable with basic mechanical work and who want a single-source rebuild for a 46-inch MTD/Toro/White tractor. Skip it if you only need one spindle or blade, or if your deck is rusted beyond repair.
