## Description

Product description Experience the Grasshopper Advantage Extend Your Mower's Life with Genuine Original Equipment Manufacturer Parts When you invest in quality Grasshopper zero-turn equipment, don't be tempted to save a few dollars on generic aftermarket parts that can reduce your mower's power or efficiency. Protect your investment and ensure peak performance by trusting only genuine Grasshopper replacement parts and supplies to maintain your Grasshopper zero-turn mower. Aftermarket parts have proven time and time again to be unacceptable. Grasshopper parts are manufactured to meet ultra-precise engineering specifications, and can help you maximize performance and significantly extend the life of your mower. GrassMax Blade System Hi-Lo Mulching Blade Designed for use with all mulching packages beginning with SN 5700000 and above. In conjunction with the Down Discharge mulching baffles, High-Low Mulching blades recut clippings multiple times thanks to an extended cutting edge and a carefully crafted rise and fall airflow pattern that helps clippings disappear into the turf canopy. Medium Lift Blade Recommended for use with all PowerVac Collection Systems. Medium Lift blades are required with certain mulching packages - use Medium Lift blades with any mulching package that originally included Medium Lift blades. Also recommended for most rear discharge decks. High-lift Notched Blade Recommended for most normal side-discharging applications, from the moist grass conditions of early spring to final mowing in the fall. Available with optional LaserEdge EverSharp technology that requires no sharpening for the life of the blade. Extreme High-lift Notched Blade Recommended for side-discharge applications in very lush or overgrown conditions. They are recommended for use with liquid-cooled models or air-cooled models greater than 23 hp. Quality You Can Afford Don't Cut Corners on Quality Known for quality, reliability and value, Grasshopper True ZeroTurn MidMount and FrontMount mowers are the machine of choice among smart professionals and consumers. Grasshopper Mower provides replacement parts and accessories for your ZeroTurn Lawn Mower such as belts, blades, decks, bolts, oil filters, and more!

Engine Air Filters Oil & Air Filters Superior filtration is an absolute essential when it comes to keeping your Grasshopper operating at maximum efficiency. Abrasive particles can damage valves and other components. Genuine Grasshopper filters are designed to protect the engine and extend service life — so you can get the most out of your equipment investment. Explore the benefits and see why genuine Grasshopper parts are a "must have" for any owner. Dust is an engine's worst enemy, and using inferior quality aftermarket filters on your Grasshopper zero-turn mower can allow dust to cause premature wear and possible failure of the engine. Using genuine OEM filters will ensure a proper fit and tight seal to prevent dust from reaching the engine. An after-market filter will not provide an exact fit, increasing the likelihood of engine contamination. OEM filters will keep your engine in peak operating condition and prolong the service life of your mower. MaxLife Belts Aftermarket belts of the same length are not designed for the specific pulleys, tension and flexibility required of Grasshopper OEM belts. MaxLife premium industrial-grade belts are design-matched to conform to rigid Grasshopper specifications for material, dimension, shape, construction and pliability to ensure superior performance and the longest possible service life. Only OEM belts are engineered and manufactured for optimum service life and performance, so always look for the Grasshopper logo on the belt to ensure superior performance.
