Jason Industrial MXV4-780 Kevlar V-belt 1/2x78 in

Product Description

The JASON INDUSTRIAL MXV4-780 is a Kevlar-reinforced V-belt designed for demanding drive applications in farm, lawn, and garden equipment. Measuring 1/2 inch wide and 78 inches in length, this belt delivers high tensile strength with reduced stretch compared to standard rubber belts. The Kevlar cord construction resists heat, oil contamination, and side-load stress, making it well suited for the variable-speed and high-torque conditions common in outdoor power equipment. Equipment operators and service technicians choose Kevlar-core belts when durability and reduced replacement frequency are priorities.

This belt is intended for use on farm implements, lawn tractors, garden tractors, and related outdoor power equipment where a 1/2-inch cross-section V-belt drive is specified. It is a direct replacement in applications requiring an MXV4-series belt profile. Service technicians performing seasonal maintenance or mid-season belt replacements will find this belt fits standard V-belt sheaves designed for the 1/2-inch cross-section profile.

Key Features

• Kevlar cord construction provides high tensile strength with minimal stretch
• 1/2 inch width by 78 inch length for precise drive-system fitment
• Resistant to heat, oil, and side-load stress in outdoor power equipment environments
• MXV4-series profile fits standard 1/2-inch cross-section V-belt sheaves
• Suitable for variable-speed and high-torque drive applications

Compatibility

Designed as an OEM-style replacement for farm, lawn, and garden equipment requiring a 1/2-inch cross-section V-belt of 78 inches in length.

Installation Notes

Belt replacement should be performed by a qualified equipment technician with the machine fully powered down and all stored energy released before beginning work. Remove tension from the drive system before removing the old belt, and inspect all sheaves and pulleys for wear or misalignment prior to installing the new belt. Proper belt tension should be set per the equipment manufacturer's specification — do not over-tension, as this accelerates bearing and belt wear. Refer to the equipment service manual for sheave alignment procedures.
