Hydraulic Pump Idler Pulley Arm Assembly for Spartan Zero Turn Mower Drive System SKU: 490-0018-00-P11

When your mower's hydraulic pump drive belt starts slipping, wandering off track, or wearing prematurely, it's often a failing idler pulley arm assembly that's causing the trouble. Without proper belt tension and alignment, your hydrostatic drive system loses power, operates erratically, or fails completely during critical mowing jobs. This replacement assembly restores the precise belt guidance and tension your Spartan mower's hydraulic system requires for reliable operation.

• Heavy-duty metal construction built to handle the stress of commercial zero-turn operation
• Precision pivot points maintain consistent belt tension throughout the mowing cycle
