121-5765 Drive Belt for Toro Timemaster 30" Mower (2-Pack) - Replaces 20199, 20200, Fits Turfmaster, Exmark ECKA30-1/2 x 30.1" Wrap-Molded Aramid Cord PTO Belt

What It Is

This is a 2-pack of wrap-molded aramid cord PTO drive belts for the Toro Timemaster 30" mower. It engages the cutting blades and is also used on Turfmaster and Exmark ECKA30 models with the same 1/2 x 30.1" belt spec.

Fitment & Compatibility

Before buying, confirm your mower uses a 1/2-inch wide x 30.1-inch long belt. This replaces OEM part numbers 20199 and 20200. It fits:

• Toro Timemaster 30" (models 21199, 21200, 21201, 21202, 21203)
• Toro Turfmaster 30" (models 22170, 22171, 22172, 22173)
• Exmark ECKA30 (Kubota engine models)

Measure your old belt’s length (lay flat, measure outer circumference) and width. If it’s not exactly 30.1" x 1/2", this won’t fit. Check your mower’s model number sticker under the seat or on the frame—this is not universal for all 30" decks.

Key Things to Know

• Quality: Aramid cord is stronger than standard rubber belts, but aftermarket belts may vary in durability vs. OEM. This pack is priced competitively, but some users report shorter lifespan than genuine Toro belts.
• Installation: Moderate difficulty—you’ll need to remove the blade pulley and belt guides. Watch for a spring-tensioned idler pulley; mark belt routing before removal. A belt diagram is often printed on the deck.
• Common Gotcha: The 2-pack is convenient, but if your mower is over 5 years old, check pulley bearings and idler arm for wear before installing—a seized pulley will shred a new belt fast.
• Fit Note: This is not for the Timemaster 21" or any 22" deck models—verify deck size.

Should You Buy It

If you own a Toro Timemaster or Turfmaster 30" and need a spare belt on hand, this 2-pack offers good value. It’s a solid budget option for everyday mowing, but if you mow heavy, wet, or tall grass frequently, consider paying more for an OEM belt for longer life. For light-to-moderate use, this will get the job done.
