Autoparts 131-4529 125-2532 Pulley Kit Replacement for Toro 30 Timemaster Turfmaster Lawnmower Use on 20199, 20200, 20975, 20977, 21199, 21200 Mower 2 Pack

What It Is

This is a 2-pack replacement pulley kit (part numbers 131-4529 and 125-2532) designed for the blade drive system on Toro 30-inch TimeMaster and TurfMaster lawn mowers. It replaces the original pulleys that spin the cutting blades, restoring belt tension and cutting performance.

Fitment & Compatibility

Before buying, verify these three things:

• Deck size: Only fits 30-inch decks on TimeMaster and TurfMaster models. Will not work on 22-inch or 42-inch mowers.
• Model numbers: Confirmed for Toro models 20199, 20200, 20975, 20977, 21199, and 21200. Check your mower’s model plate (under seat or on frame).
• OEM vs aftermarket: This is an aftermarket kit, not OEM Toro. The pulleys are 4.5 inches in diameter (131-4529) and 3.5 inches (125-2532). Measure your old pulleys to confirm size match before installing.

Key Things to Know

• Installation difficulty: Moderate. Requires removing the deck belt, blade, and pulley retaining bolt. A socket wrench, torque wrench, and possibly a puller tool are needed.
• Quality note: At 4.2 stars from 10 reviews, this kit is generally reliable but some users report the pulley bearings are less smooth than OEM. Inspect for wobble before mounting.
• Common gotcha: The pulleys use a 5/8-inch shaft bore. Ensure your mower’s spindle shaft matches—some older TimeMaster models may have a different bore size. Measure before buying.
• Belt check: Replacing pulleys often means the belt is worn too. Consider replacing the deck belt at the same time to avoid premature wear on new pulleys.

Should You Buy It

If your Toro 30-inch TimeMaster or TurfMaster is losing blade speed, making squealing noises, or has visibly worn pulleys, this kit is a solid budget fix. It’s best for DIY owners comfortable with basic mechanical work—not for commercial use or those wanting OEM-grade longevity. For the price, it’s a good stopgap, but if you mow daily, spring for genuine Toro pulleys.
