Measuring 0.5 inches wide with a 39-inch outside circumference, this belt delivers high tensile strength and heat resistance where standard rubber belts fall short. The Kevlar cord construction resists stretching and cracking under heavy cyclical loads, making it a reliable choice for mower decks, tillers, and similar outdoor power equipment. Technicians and equipment service pros install this belt as a direct replacement when restoring drive train performance.\u003c\/p\u003e\u003cp\u003eThis belt is sized for use in farm, lawn, and garden equipment that requires a 4L or MXV cross-section V-belt. It fits drive systems where a 0.5-inch top width and approximately 39-inch length are specified. It is well suited for residential and light commercial outdoor power equipment, including walk-behind and riding mowers, garden tractors, and rotary tillers. Always verify the belt cross-section and length against equipment manufacturer specifications before installation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKevlar cord construction provides high tensile strength and reduced stretch compared to standard rubber belts\u003c\/li\u003e\n\u003cli\u003e0.5-inch top width and 39-inch length for precise fitment in 4L\/MXV-profile drive systems\u003c\/li\u003e\n\u003cli\u003eHeat and flex resistant for high-cycle outdoor power equipment applications\u003c\/li\u003e\n\u003cli\u003eSold individually (unit of measure: EA)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement V-belt for farm, lawn, and garden equipment requiring a 4L or MXV cross-section belt with a 0.5-inch width and 39-inch length.

Disengage all power take-offs and disconnect the spark plug or power source before removing the old belt. Inspect pulleys and sheaves for wear or misalignment prior to installing the new belt, as damaged pulleys accelerate belt wear. Do not force the belt over pulley flanges using sharp tools, as this can damage the Kevlar cord structure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBelt Width\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBelt Length\u003c\/strong\u003e: 39 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBelt Profile\u003c\/strong\u003e: MXV4 (4L\/MXV cross-section)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCord Material\u003c\/strong\u003e: Kevlar\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Farm, Lawn, and Garden Equipment\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 13 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 25\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: JASON INDUSTRIAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MXV4-390\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JASON INDUSTRIAL","offers":[{"title":"Default Title","offer_id":51524821975346,"sku":"MXV4-390","price":242.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/51d414290546a570a14069f4d561ab25_f07fd997-1be0-4c03-bcdb-66a3219664ef.jpg?v=1785458606","url":"https:\/\/voomisupply.com\/products\/jason-industrial-mxv4-390-kevlar-v-belt-0-5x39-in","provider":"Voomi Supply","version":"1.0","type":"link"}
