Pokuuer Lawn Mower Deck Belt 5/8 x 143.5 Kevlar-reinforced — OEM fit for Cub Cadet, MTD, Husqvarna & Exmark

Pokuuer's 5/8" x 143½" lawn mower deck belt is a heavy-duty replacement built with Kevlar fibers to match OEM fit for Cub Cadet, MTD, Troy-Bilt, Husqvarna and Exmark zero-turn and riding mower decks.

This replacement deck belt is engineered for direct-fit performance where the original belts 754-05078, 954-05078, 574845603 or Exmark 1-413308 are specified. It’s made from synthetic rubber reinforced with Kevlar for improved resistance to heat, oil and abrasive wear, and it fits a broad range of commercial-style and homeowner riding mowers including RZT and GT-series machines. The construction focuses on dimensional accuracy and durability so the belt tracks correctly on pulleys and maintains tension over typical mowing seasons.

Which mower models will this belt work with?

This belt replaces several OEM numbers and fits many popular zero-turn and tractor-style mowers. It’s compatible with Cub Cadet RZT-S50/RZT-S50KH, MTD ZT-L50 KH, Troy-Bilt models listed by OEM part numbers, select Husqvarna GT and GTH series machines, and Exmark decks that reference 1-413308.

• OEM cross-reference: Cub Cadet 754-05078, 954-05078; MTD 754-05078, 954-05078.
• Troy-Bilt models that use the same part numbers for RZT and ZT decks.
• Husqvarna GT/GTH/TS series as listed (GT 52XLS, GTH 3052TDF, TS 352, etc.).
• Exmark decks that accept part 1-413308 or 413308.

How does the Kevlar reinforcement benefit mowing performance?

Kevlar fibers give the belt greater tensile strength and abrasion resistance compared with non-reinforced rubber belts. That means the belt is less likely to stretch, crack or shred under heavy load, which helps maintain cutting consistency and reduces downtime for replacements.

• Improved heat and oil resistance for long life in engine compartments.
• Lower elongation helps the deck stay properly tensioned.
• Reduced fraying and edge wear on pulley corners and idlers.

What should I check before ordering to ensure correct fit?

Measure the old belt and confirm its dimensions and part number if possible: 5/8" width and a length equivalent to 143½" (inner circumference). Compare the OEM cross-reference numbers on your mower parts diagram or owner’s manual to the list provided to confirm compatibility.

• Verify belt size: 5/8" (0.625") width and 143.5" length.
• Check your mower’s parts list for 754-05078, 954-05078, 574845603, or 1-413308.
• Inspect pulleys and idlers for wear—replace them if damaged before installing a new belt.

How should I install and maintain this replacement deck belt?

Installation follows the same routing as the original OEM belt—consult your mower’s deck diagrams and safety procedures. Keep the deck clean, remove debris build-up and inspect pulleys; proper alignment and clean components extend belt life and performance.

• Route the belt according to the mower’s deck diagram and tensioner placement.
• Replace worn idlers or pulleys to prevent premature belt failure.
• Clean grass clippings and oil deposits off the deck regularly.
