Jason Industrial MXV4-770 Kevlar V-belt 0.5x77 Inches

Product Description

The JASON INDUSTRIAL MXV4-770 is a Kevlar-reinforced V-belt designed for demanding power transmission applications in farm, lawn, and garden equipment. Measuring 0.5 inches wide and 77 inches in length, this belt delivers high tensile strength and heat resistance that standard rubber belts cannot match. The Kevlar construction resists stretching and maintains consistent tension over extended service intervals, reducing downtime and re-tensioning requirements. It is a direct replacement for equipment that requires a high-performance, small-profile V-belt in this size class.

This belt is suited for residential and light commercial outdoor power equipment, including tractors, mowers, tillers, and other farm and garden machinery that use fractional-horsepower drive systems. The 0.5-inch cross-section profile fits standard sheaves and pulleys designed for this belt designation. It performs reliably in environments with exposure to heat, dust, and variable load conditions common in seasonal agricultural and landscaping applications.

Key Features

• Kevlar tensile cord construction for high strength and minimal stretch
• 0.5 inches x 77 inches dimensions for precise fitment in compatible drive systems
• Resistant to heat and abrasion in outdoor power equipment environments
• Consistent tension retention reduces re-tensioning frequency
• Designed for farm, lawn, and garden power transmission applications

Compatibility

Designed as an OEM-style replacement Kevlar V-belt for farm, lawn, and garden equipment requiring a 0.5-inch wide, 77-inch V-belt drive configuration.

Installation Notes

Belt replacement is typically performed by a qualified equipment technician or experienced operator. Disengage all power sources and allow the drive system to come to a complete stop before servicing. Release tension from the idler or adjust the drive component to allow belt removal without prying, which can damage sheave grooves. Verify sheave alignment and condition before installing the new belt to avoid premature wear.
