The walk-behind lawn mower cover by Tough Cover has been designed with longevity in mind. Constructed of heavy-duty 600D marine-grade fabric with double-stitched seams and interior waterproof coating, our cover will protect your investment for years to come. TIPS FOR CHOOSING A HIGH-QUALITY MOWER COVER. FABRIC TYPE: Fabric strength is determined by a “Denier” number. Denier (abbreviated D), is a unit of measure for the mass density of fibers. Simply put, the higher the denier number, the stronger the fabric. Many mower covers are made with 300D, 200D, or even 150D fabric, which is a much less durable material. Our 600D fabric is robust enough to withstand the harshest environment. COVER WEIGHT: Compare the item weight when shopping for a new cover. A cover made with thin, flimsy material will be very light. At 2.1 lbs, this black lawn mower cover by Tough Cover is one of the heaviest, most durable covers on the market. WARRANTY: We stand behind our 12-month unconditional warranty and take pride in offering unparalleled customer service.
