The JASON INDUSTRIAL MXV4-370 is a Kevlar-reinforced V-belt designed for reliable power transmission in demanding outdoor power equipment applications. Measuring 0.5 inches wide and 37 inches in length, this belt delivers the high tensile strength and heat resistance that Kevlar construction provides over conventional rubber belts. The MXV4 series is engineered to resist stretching, cracking, and glazing under the repetitive load cycles common in farm, lawn, and garden machinery. Service technicians and equipment operators working on this class of equipment rely on Kevlar-core belts when longer service intervals and reduced downtime are priorities.
This belt is suited for farm equipment, lawn tractors, riding mowers, garden tillers, and similar outdoor power machinery that uses a standard 0.5-inch cross-section V-belt drive system. Its 37-inch outside circumference fits drive systems where dimensional accuracy is critical to maintaining proper belt tension and drive efficiency. The Kevlar tensile cord construction makes it a preferred replacement in applications where OEM rubber belts have shown premature wear or slippage under heavy or variable loads.
Designed as an OEM-style replacement V-belt for farm, lawn, and garden equipment using a 0.5-inch wide, 37-inch V-belt drive configuration.
V-belt replacement on outdoor power equipment should be performed by a qualified technician with the engine stopped, the ignition key removed, and the spark plug wire disconnected before accessing the drive system. Relieve all belt tension by loosening the drive component or idler before removing the worn belt, and inspect pulleys for wear, misalignment, or debris before installing the new belt. Do not use belt dressing compounds on Kevlar-core belts, as these can degrade the cord and reduce belt life. Verify correct belt tension per the equipment manufacturer specifications after installation.
