Faugcol mower deck belt 5/8" x 143 1/2" — replacement for Cub Cadet/MTD/Husqvarna, deck-drive durability

Faugcol 954-05078 is a 5/8" x 143 1/2" replacement mower deck belt engineered to restore smooth power transfer for compatible zero-turn and garden tractors.

If your mower blade engagement feels sluggish or the deck belt shows glazing, cracking, or slipping, replacing it with a correctly sized belt is the fastest way to get cutting performance back. This Faugcol belt matches the dimensions and fitment of several factory part numbers, including Cub Cadet 954-05078, MTD 754-05078, Husqvarna 574845603, and Exmark 1-413308. It’s intended specifically for deck drive systems on a range of zero-turn and lawn tractor models where a 5/8" width and 143 1/2" length are required.

How will this belt affect mowing performance?

Installing a properly sized deck belt ensures consistent power delivery from the engine to the blade pulleys, which prevents belt slip under load and maintains even blade speed. That translates to cleaner cuts and fewer missed passes when tackling thicker grass or inclines. A new belt also reduces heat buildup and premature wear on pulleys and idlers.

• Restores correct blade RPM under normal operating load
• Reduces slipping and vibration for smoother cut quality
• Protects pulleys and bearings by maintaining tension

Which machines and part numbers is this compatible with?

This replacement was made to match the listed OEM sizes and cross-reference numbers so it fits a broad range of models from several manufacturers. Always compare the belt’s width and length and your mower’s OEM part number before ordering to ensure fit. It’s ideal for many Cub Cadet, MTD, Troy-Bilt, Husqvarna, and Exmark decks that specify the cross-referenced numbers.

• Compatible with Cub Cadet RZT-S50 and RZT-S50KH zero-turn models
• Fits MTD ZT-L50 KH and Troy-Bilt 17ARCACQ011 / 17ARCACQ211
• Works with Husqvarna GT/ GTH/ TS 52-series and similar decks
• Cross-references: Cub Cadet 954-05078, MTD/Troy-Bilt 754-05078, Husqvarna 574845603, Exmark 1-413308

What are the dimensions and construction details?

This belt measures 5/8" in width and 143 1/2" in circumference, the two critical dimensions for deck applications. It’s built for deck-drive use, designed to resist common deck stresses like high RPM, heat, and the intermittent loads of blade engagement. While installation environment and operator practices affect longevity, the belt is manufactured to meet the expected mechanical specifications of the OEM cross-references.

• Nominal width: 5/8" (0.625 inch)
• Nominal length: 143 1/2" (circumference measurement)
• Constructed for deck drive application and repeated engagement

How easy is it to install and maintain?

Replacing a deck belt is a routine maintenance job for most DIY mower owners; many models allow access by lowering the deck and removing a few fasteners or idler covers. Use the manufacturer’s service manual for correct routing and tension procedures to avoid premature wear. Regularly inspect the belt and pulleys and keep debris cleared from the deck for the longest service life.

• Follow OEM routing diagrams and tension specs during installation
• Inspect pulleys and idler bearings; replace if worn before fitting new belt
• Keep deck area free of grass build-up and replace belt at first signs of damage

Who is this for: This Faugcol replacement deck belt is made for homeowners, landscapers, and maintenance crews who operate compatible Cub Cadet, MTD, Troy-Bilt, Husqvarna, or Exmark zero-turn and lawn tractor decks that require a 5/8" x 143 1/2" belt. It’s suited to those who want a direct-fit replacement to restore reliable deck drive performance without modifying pulleys or hardware.
