Saiyugty Replacement Idler Pulley 3-Pack for Toro/Exmark Lawn Tractor Decks — Fits 32"–54", Direct-Fit OEM-Compatible

Saiyugty 3-pack flat idler pulleys replace Toro/Exmark 106-2175 and 132-9420 to restore belt tracking and smooth deck operation on compatible lawn tractors.

This replacement set includes three flat idler pulleys engineered to fit many Toro, Exmark and Lawnboy riding mower decks (sizes 32"–54") and select commercial zero-turn models. Each pulley is manufactured to the approximate dimensions of the original part (outer diameter ~104.8 mm, inner bore ~9.5 mm, height ~35 mm) so it installs in the same locations as the factory component. The pack gives you spares for multiple decks or future maintenance intervals, helping you avoid downtime during mowing season.

Which machines will these Saiyugty pulleys fit?

These pulleys are compatible with a broad range of Toro and Exmark deck models as well as several Lawnboy riding mowers. They match common OEM numbers so you can cross-reference quickly.

• Fits Toro TimeCutter, Z-series, MX-series and other listed models.
• Compatible with Exmark Quest, E-Series and S-Series decks (42", 48", 50", 54" where specified).
• Works with Lawnboy Z310, Z330, Z320 H and related riding mowers.
• Check original part numbers 106-2175 / 132-9420 to confirm fit before purchase.

How easy is installation and what should I prepare?

Installation is straightforward if you follow the mower manufacturer’s instructions and basic safety steps. The pulleys are direct-fit replacements that slide onto the same shafts and fasteners as the originals.

• Disconnect battery and any power sources before starting work.
• Measure the existing pulley: OD ~4-1/8", ID ~3/8", height ~1.4" to confirm match.
• Use owner’s manual torque and reassembly steps for correct belt tension and alignment.
• Keep a spare pulley from this 3-pack for next maintenance to minimize future downtime.

What performance or durability benefits can I expect?

Replacing a worn idler pulley restores correct belt path and reduces slippage, noise, and uneven blade engagement. Saiyugty pulleys are built to match factory geometry so belts run true and wear is reduced.

• Restores consistent belt tracking for smoother deck operation.
• Reduces vibration and squealing caused by failing pulleys or bearings.
• Extends belt life by maintaining correct alignment and tension.
• Three units per pack give value for multi-deck fleets or future replacements.

Who is this for: Lawn care professionals, property owners with compatible Toro/Exmark/Lawnboy tractors, and DIY maintenance enthusiasts who need reliable, OEM-compatible idler pulleys. Buy this 3-pack if you want direct-fit replacements that match common Toro and Exmark part numbers (106-2175 / 132-9420) and prefer keeping spares on hand for quick repairs. Always verify your mower’s part number and follow the manufacturer’s installation and safety instructions when replacing pulleys.
