120-7082 Idler Pulley for time-Master 30" Lawn mowers Compatible with to-ro Turf-Masters - Exmark Commercial 30 Walk-Behind for ECKA30 21199HD 21200 22200 22210 22215 20977 Models

What It Is

This is a replacement idler pulley (part 120-7082) that guides and tensions the drive belt on 30-inch walk-behind mowers. It’s designed for Toro TimeMaster and TurfMaster models, plus Exmark Commercial 30 walk-behinds—heavy-use machines for large lawns or commercial crews.

Fitment & Compatibility

Before buying, confirm your mower model and deck size. This pulley fits:

• Toro TimeMaster 30” (models 21199HD, 21200, 22200, 22210, 22215, 20977)
• Toro TurfMaster 30” (all recent versions)
• Exmark ECKA30 (30” commercial walk-behind)

Check your existing pulley’s outer diameter (should match 3.5 inches) and shaft bore size (typically 5/8 inch). This is an aftermarket replacement for OEM part 120-7082; verify your belt routing and pulley flange orientation (flat vs. flanged) match your setup. If your mower uses a different belt width or tension spring, this pulley may still fit, but double-check clearance against the deck.

Key Things to Know

• Quality: Steel construction with a sealed bearing—holds up well under commercial use, but the bearing may wear faster than OEM if debris gets in.
• Installation: Simple—remove belt, unbolt old pulley (likely a 3/8-inch bolt), swap, and re-tension belt. Takes 10-15 minutes.
• Common gotcha: The flange can be slightly thicker than OEM; verify it doesn’t rub against the belt or deck. If your old pulley had a spacer, reuse it.
• Price vs. OEM: At $8.49, it’s roughly half the cost of a Toro branded pulley. Good value for homeowners; pros may prefer OEM for longer bearing life.

Should You Buy It

If you own a Toro TimeMaster or TurfMaster 30” or Exmark ECKA30 and need a quick, affordable fix for a noisy or seized idler pulley, this is a solid buy. It’s fine for residential use and light commercial. For heavy daily commercial cutting, consider OEM for potentially longer bearing longevity, but this will get the job done at a fraction of the cost.
