GELASKA 3 Pack 132-9420 Flat Idler Pulley Replaces 106-2175 for Toro Timecutter SS5000 SS5035 SS5060, MX5000 MX5025 MX5050 MX5060 MX5075, SW5000 SWX5000 SWX5050, ZS5000 ZS5000tf 50 inch Deck Mowers

What It Is

This is a flat idler pulley, OEM replacement part number 132-9420 (also replaces 106-2175), designed to guide and tension the drive belt on 50-inch deck Toro TimeCutter, MX, SW, and ZS series zero-turn mowers. It reduces belt friction and vibration, preventing belt slip and premature wear.

Fitment & Compatibility

Before buying, confirm your mower has a 50-inch cutting deck—this pulley does not fit 42-inch or 54-inch decks. Compatible models include: Toro TimeCutter SS5000, SS5035, SS5060; MX5000, MX5025, MX5050, MX5060, MX5075; SW5000, SWX5000, SWX5050; ZS5000, ZS5000tf. Check your deck’s belt routing diagram to ensure the pulley’s 3-inch outer diameter and 5/8-inch bore match your existing idler. This is an aftermarket part, not genuine Toro, but it directly replaces OEM part numbers 132-9420 and 106-2175.

Key Things to Know

• Quality: Users report durable steel construction with a sealed bearing; 4.6-star rating from 219 reviews suggests good reliability for the price.
• Installation: Easy—removes with a single bolt or nut (typically 5/8-inch or 1/2-inch socket). No special tools needed, but a torque wrench to 25-30 ft-lbs is recommended.
• Common gotcha: The pulley’s flat profile is critical—if your deck uses a V-groove idler, this won’t work. Also, check your belt for wear before replacing; a worn belt can damage a new pulley quickly.
• Pack: Comes as a 3-pack, so you have spares or can replace all idlers on the deck at once. Note: Some decks use only one or two idlers—verify your count.

Should You Buy It

If you own a 50-inch Toro TimeCutter, MX, SW, or ZS mower and need a reliable, budget-friendly replacement for a worn or noisy idler pulley, this 3-pack is a solid choice—especially if you want spares or plan to do a full deck service. Skip it if you prefer genuine Toro parts or have a non-50-inch deck.
