121-5765 Belt for Toro 30" Time Master Turf Master 20199 20200 20975 Compatible with Exmark Lawnmower PTO Belt Parts (2 Pack)

What It Is

This is a two-pack of PTO drive belts (OEM part 121-5765) designed specifically for Toro 30" TimeMaster and Turf Master mowers. It transfers power from the engine to the cutting deck blades, and is also compatible with select Exmark zero-turn mowers.

Fitment & Compatibility

Check these before buying:

• Deck size: Fits only 30" decks (not 22", 42", etc.).
• Model numbers: Toro TimeMaster 20199, 20200; Turf Master 20975. Also fits Exmark models using the same PTO belt (verify your Exmark part number).
• OEM vs aftermarket: This is an aftermarket belt, not genuine Toro. It matches OEM specs but may differ slightly in material or tension.
• Measurements: Belt is 1/2" wide x 88.5" effective length. Measure your old belt if possible—cross-check against your model’s parts diagram.

Key Things to Know

• Installation difficulty: Moderate. You’ll need to release belt tension by removing the deck belt guide or idler pulley. No special tools, but take photos before disassembly.
• Two-pack value: Cheaper per belt than buying singles. Keep the spare for quick replacement—PTO belts on 30" decks wear faster under heavy use.
• Quality note: Some users report slightly shorter lifespan than OEM Toro belts (1-2 seasons vs 2-3). Fine for homeowner use; pros may prefer genuine Toro.
• Common gotcha: The belt may feel tight on first install. Run the mower for 5 minutes at low throttle, then re-check tension—it will seat and loosen slightly.

Should You Buy It

Buy this if you own a Toro 30" TimeMaster or Turf Master and want a cost-effective, ready-to-go replacement pair. It’s a solid value for homeowners who mow weekly and don’t mind swapping a belt every couple of years. Skip it if you need OEM reliability for commercial use—stick with genuine Toro for the longest life and perfect fit.
