HQPASFY Flat Idler Pulley Set — 3-Piece Direct-Fit for John Deere Z245–Z445 48"/54" Decks, Corrosion-Resistant

If your John Deere zero-turn mower's deck belt routing needs a durable, like-for-like pulley replacement, this HQPASFY flat idler pulley set gives three direct-fit metal pulleys sized for common OEM part numbers. Designed to match the original mounting and bearing dimensions for many Z-series mowers with 48" or 54" decks, the set helps restore proper belt tension and tracking with corrosion-resistant construction engineered for outdoor use.

Which John Deere models and deck sizes will these pulleys fit?

These pulleys are made to fit a range of John Deere zero-turn models that use the specified OEM numbers. They cover Z245, Z255, Z355E, Z425, Z435 and Z445 when equipped with either 48" or 54" cutting decks. Always compare your current pulley part number and dimensions before buying to confirm compatibility.

• Compatible models: Z245, Z255, Z355E, Z425, Z435, Z445
• Deck sizes: 48" and 54" configurations
• OEM references replaced: AM135526, AM128118, AM143737/AM136693

What are the exact dimensions included in this three-piece pulley set?

The package contains three pulleys sized to match common OEM variations so you can replace the specific pulley on your mower deck. Each pulley lists width, outside diameter (OD) and inner bore (ID) so you can verify fitment against your existing components.

• AM128118: Width 1.2" • OD 4.7" • ID 0.7"
• AM135526: Width 1.2" • OD 5.1" • ID 0.7"
• AM143737: Width 0.9" • OD 5.9" • ID 0.7"

How durable and easy to install are these replacement pulleys?

Each pulley is manufactured from sturdy metal with a finish that resists corrosion and surface wear commonly caused by outdoor exposure and mowing debris. They are designed for direct replacement of the listed part numbers and install using the same mounting points as the OEM items, reducing downtime during maintenance.

• Material: corrosion- and abrasion-resistant metal construction
• Performance: built for long service life in outdoor conditions
• Installation: direct-fit replacement; uses original mounting and hardware
• Safety note: disconnect power and wear gloves before servicing the deck

When should I choose this HQPASFY set instead of a single pulley?

If your mower uses multiple idler pulleys or if you’re unsure which exact pulley failed, buying the three-piece set covers the common variants that appear on Z-series decks. Having spares on hand simplifies future repairs and can prevent another mowing interruption when a different pulley later shows wear.

• Good for complete deck tune-ups or multi-pulley systems
• Eliminates repeat orders if another pulley fails later
• Useful when exact OEM number is uncertain—verify sizes to confirm fit

Who is this for: Landscapers, homeowners and maintenance technicians who operate John Deere Z245–Z445 zero-turn mowers with 48" or 54" decks and need a reliable, OEM-matching idler pulley replacement. Choose this HQPASFY three-pulley set when you want metal pulleys sized to standard OEM dimensions, corrosion resistance for outdoor durability, and straightforward direct-fit installation to get your mower deck back to proper belt alignment quickly.
