Superior Quality & Performance
The M154960 mower deck belt offers up to 120% better performance compared to standard belts. It delivers extended fatigue life (up to 120 hours) and increased bonding strength (2.64 kN/m).
Constructed from thick chloroprene rubber and reinforced with strong aramid fiber cords, the belt is wrapped in a durable two-layer fabric coating. This design provides excellent resistance to heat, oil, and wear while ensuring strong adhesion to mower pulleys and minimizing belt slippage.
Efficient Power Transmission
This deck belt transfers power from the engine to the mower blades, enabling smooth blade rotation and consistent cutting performance.
Replace the belt if you notice signs such as cracks, rolling or flipping, sidewall damage, or burned or glazed belt surfaces.
