121-5765 Drive Belt fits Toro Timemaster Turfmaster Mower 30" Deck 20199 20200 (2 Pack)

What It Is

This is a two-pack of drive belts (OEM part 121-5765) for Toro Timemaster and Turfmaster mowers with a 30-inch cutting deck. It transfers power from the engine to the blade spindles, enabling the dual-blade cutting system. Designed for models 20199 and 20200.

Fitment & Compatibility

Before buying, confirm your mower has a 30-inch deck and is a Toro Timemaster (models 20199, 20200) or Turfmaster. Check your current belt’s part number—it should match 121-5765. Measure the belt: it should be approximately 1/2 inch wide and 96 inches long. This is an OEM replacement; aftermarket belts may differ in tension and durability. Verify your mower uses a single drive belt (not a separate deck belt). If your model uses a different belt (e.g., 121-5764), this won’t fit.

Key Things to Buy

• Quality concerns: This belt pack has a 3.1-star rating—some users report premature wear or stretching. Inspect for defects before installation.
• Installation difficulty: Moderate. You’ll need to remove the deck shield and tensioner pulley. Allow 30–60 minutes; have a wrench and belt tool ready.
• Common gotcha: The belt must be routed correctly around the tensioner and both spindles. Misrouting causes slippage or blade damage. Check your manual’s diagram.
• Two-pack value: You get two belts for one price, but if the first fails quickly, the second may as well. Consider buying a single OEM belt if longevity is critical.

Should You Buy It

Buy this if you need a quick, budget-friendly replacement for a Toro Timemaster or Turfmaster 30-inch mower and can handle a moderate DIY install. Skip it if you prioritize long belt life or have had issues with aftermarket belts—opt for a genuine Toro single belt instead.
