Mower Deck Belt Idler Pulley for Spartan Zero Turn Mowers SKU: 132-9420

When your mower deck belt starts squealing, slipping, or wearing prematurely, a worn idler pulley is often the culprit. This genuine Spartan replacement restores proper belt tension and alignment, eliminating belt slippage and ensuring consistent cutting performance across your entire deck width.

Why Genuine Matters

• Precision-engineered bearing and pulley wheel designed for Spartan's specific belt routing
• Built to withstand the constant vibration and outdoor conditions your mower faces

• Quality construction prevents premature bearing failure and wobbling under load

A failing idler pulley doesn't just cause noise—it leads to uneven cuts, belt damage, and potential deck drive failure when you need your mower most. This Spartan original equipment part keeps your belt system running smoothly season after season.
