131-4529 Pulley Kit Fit for Toro 30" Deck Mower Timemaster Turfmaster Lawnmower Replace 131-4509 125-2532

What It Is

This pulley kit replaces the factory idler and tension pulleys on Toro 30-inch deck mowers, specifically the Timemaster and Turfmaster models. It’s designed to restore proper belt tension and drive engagement when original pulleys wear out or seize.

Fitment & Compatibility

• Fits: Toro 30" deck mowers—Timemaster (models 21199, 21200, 21201, 21202) and Turfmaster (models 22171, 22172, 22173, 22174).
• Replaces OEM: Toro part numbers 131-4509 and 125-2532.
• Check before buying:
  • Measure your existing pulley outer diameter (should match ~3.5") and shaft bore size (typically 5/8").
  • Verify your deck model number (stamped on the deck or frame near the discharge chute).
  • This kit is aftermarket—OEM Toro pulleys are identical in dimensions but may use different bearings.
• Not compatible: 21" or 42" decks, or non-Toro mowers.

Key Things to Know

• Quality: Aftermarket pulleys are generally comparable to OEM, but bearing seals may be less durable in wet/debris-heavy use.
• Installation: Moderate difficulty—requires removing the belt, center deck bolt, and possibly a puller if the old pulley is seized.
• Gotcha: The kit includes two pulleys; make sure you match the correct one to the idler vs. tension arm (they’re usually identical, but check your deck diagram).
• Lifespan: Expect 2–3 seasons under normal residential use; commercial duty may wear bearings faster.

Should You Buy It

If your Toro 30" Timemaster or Turfmaster has a squeaking belt, wobbling pulley, or uneven cut, this kit is a cost-effective fix. It’s a solid choice for DIY owners who want to avoid a $50+ OEM part, provided you’re comfortable with basic deck disassembly. Skip it if you need exact OEM bearings for heavy commercial use—stick with genuine Toro.
