JUQAFY Drive Idler Pulley & Drive Belt Kit Fits Husqvarna Z254F/Z246/Z254, Reinforced Belt & Alloy Pulley

JUQAFY Drive Idler Pulley & Drive Belt kit restores dependable drive power to compatible zero-turn and lawn tractors by eliminating belt slippage and noisy idler operation.

This replacement kit includes a precision idler pulley and a reinforced drive belt engineered to fit many Husqvarna Z-series models, Poulan Pro PRZ5426KH, and Craftsman 917378XXX-series mowers. Built from durable alloy and high-grade rubber, the pair is designed to restore proper tension, reduce vibration and help your mower transfer engine power consistently to the drive system. The kit is offered as a direct-fit replacement for OEM part numbers 539110311 and 539110411, and comes ready for bolt-in installation.

How will this kit stop belt slipping and reduce abnormal mower noise?

The idler pulley maintains correct belt tension while the drive belt delivers torque between the engine and drive components. Together they eliminate slack that causes slipping and the squeals associated with misaligned or worn belts. Installing both parts at once ensures balanced wear and quieter operation.

• Taut pulley rotation reduces belt vibration and side-to-side movement.
• Reinforced rubber belt resists stretch that leads to slippage.
• Alloy pulley resists warping and keeps consistent alignment under load.

Which mower models and part numbers does this replace?

This kit was sized to work with a range of Husqvarna Z-series zero-turns, select Poulan Pro mowers and Craftsman 917378XXX machines. It serves as a direct replacement for the listed OEM part numbers so you can swap components without modification.

• Fits Husqvarna Z254F (2018–2023), Z254 (2016–2021), Z246 (2015–2022).
• Compatible with Poulan Pro PRZ5426KH (2019–2022) and Craftsman 917378XXX (2017–2020).
• Replaces OEM 539110311 and 539110411 for straightforward installation.

What materials and durability can I expect from the idler and belt?

The kit pairs a corrosion-resistant alloy idler with a high-grade rubber drive belt engineered for heat and wear resistance. These materials are selected to withstand seasonal temperature swings, humidity and typical lawn-mower loads without premature failure.

• Alloy pulley resists rust and maintains dimensional stability.
• Heavy-duty rubber belt resists stretch and abrasion.
• Designed for extended service life versus worn OEM rubber components.

How easy is installation and what does the package include?

JUQAFY ships the kit with one drive idler and one drive belt sized for direct replacement, so installation is a straightforward swap for most mechanically inclined owners and service technicians. No custom trimming or special tools beyond standard mower maintenance equipment are typically required.

• Package contents: 1 drive belt and 1 drive idler pulley.
• Direct replacement fit—mounting hardware typically re-used from the original assembly.
• Support: contact seller email for fitment questions or installation help.

Who is this for: This JUQAFY replacement kit is aimed at homeowners and small-property landscapers who own compatible Husqvarna, Poulan Pro or Craftsman zero-turn and lawn tractors and need a reliable, OEM-replacement solution for slipping belts or noisy drive pulleys. It’s also suitable for maintenance shops that perform routine drive-system overhauls and want durable components that return proper tension and smoother drive operation.
