3 Pack 106-2175 132-9420 Idler Pulley Compatible for Toro Exmark Part 32" 38" 42" 50" 54" Lawn Tractor Deck Quest E-Series S-Series Timecutter, Black

What It Is

This 3-pack of idler pulleys (models 106-2175 / 132-9420) replaces the belt tension pulleys on Toro and Exmark zero-turn and lawn tractor decks. Designed for 32" to 54" cutting decks, it keeps the drive belt taut so blades spin at full speed without slipping or wobbling.

Fitment & Compatibility

Before buying, check these three things:

• Deck size: Fits 32", 38", 42", 50", and 54" Toro/Exmark decks. Does not fit 44" or 60"+ decks.
• Model series: Compatible with Toro TimeCutter, Quest, E-Series, S-Series, and Exmark Lazer Z, Quest, and Turf Tracer. Not for older Toro Wheel Horse or Craftsman decks.
• OEM cross-reference: Replaces OEM Toro 106-2175 and 132-9420. Aftermarket part, so verify pulley diameter (approx. 3.5") and bearing width (0.75") match your original. If your original has a different spindle height or bearing seal style, this may not fit.

Quick check: Remove one pulley from your deck and measure the outside diameter and the center hole size (usually 5/8" or 3/4"). If they match, you’re good.

Key Things to Know

• Quality vs OEM: These are aftermarket pulleys with sealed bearings. They typically last 1-2 seasons under normal use, while OEM Toro pulleys may last 3-4. Fine for homeowners, less ideal for commercial mowing.
• Installation difficulty: Easy DIY job. You’ll need a socket wrench (usually 9/16" or 1/2"), a breaker bar for stubborn bolts, and a pry bar to relieve belt tension. No special tools required.
• Common gotcha: The pulley bolt is reverse-threaded on some Toro decks (lefty-tighty, righty-loosy). Check before you strip the head. Also, the belt may need re-routing after replacing multiple pulleys—take a photo before disassembly.
• Pack value: You get three pulleys for about the price of one OEM. If your deck uses two or three idlers, this is a cost-effective way to replace them all at once.

Should You Buy It

Buy this if you own a Toro TimeCutter or Exmark Quest with a 42"-54" deck and want a budget-friendly, ready-to-install replacement for worn or noisy idler pulleys. It’s ideal for homeowners who mow weekly and don’t need commercial-grade longevity. Skip it if you have a 44" or 60" deck, need exact OEM fitment for a warranty, or mow commercially and prefer longer-lasting parts.
