What It Is

This is a complete 50-inch mower deck rebuild kit for Toro TimeCutter and MX series zero-turn mowers. It includes three spindle assemblies, three blades, three idler pulleys, and one drive belt—everything needed to restore cutting performance and replace worn deck components in one purchase.

Fitment & Compatibility

Before buying, confirm your mower model is one of these: Toro TimeCutter SS5000, SS5060, MX5000, MX5060, or Z5000. The deck must be 50 inches. Check your existing spindle part numbers—this kit replaces OEM spindles 117-0751 and 121-0751. Blades are 110-6837-03 (OEM) or equivalent. Idler pulleys are 106-2175, and the belt is 119-8820 (50-inch deck belt). Measure your deck width and verify belt length (likely 119-8820 is 1/2" x 120"). If your deck is not 50 inches or your model isn’t listed, this kit won’t fit.

Key Things to Know

• Quality: Kit uses aftermarket parts that match OEM specs. Blades are standard-duty; replace with high-lift blades if you bag or cut tall grass.
• Installation difficulty: Moderate. Requires removing the deck, disassembling spindles, pulleys, and belt. Basic tools (socket set, wrench) and a jack or blocks to lift the mower. Allow 2–3 hours.
• Common gotchas: Spindle bolts may be seized—use penetrating oil and impact wrench. Idler pulley bearings are pre-greased; don’t add grease. Belt routing is specific; note tensioner position before removal. Blade orientation: sharp edge leads rotation.
• Value: At $129.99, this is cheaper than buying each part separately (spindles alone often cost $40–60 each). Verify all parts are included before starting—missing pieces can stall your job.

Should You Buy It

Buy this kit if your Toro TimeCutter or MX zero-turn has a 50-inch deck with worn spindles (noisy, wobbly), dull blades, and a loose or cracked belt. It’s a cost-effective one-stop rebuild for restoring smooth, even cuts. Skip it if you only need blades or a belt separately, or if your mower uses different spindle or deck sizes.
