Built for Real Farm Work
This belt fits a wide range of agricultural equipment where reliable power transmission matters. From mower decks that need consistent blade speed to PTO-driven implements that can’t afford to slip under load, this belt handles the demanding conditions you put it through. It’s also commonly used on generators, pumps, and other stationary equipment around the farm.
Made to Last

The materials are chosen specifically to handle temperature swings, UV exposure, and the vibration that comes with agricultural applications. You’ll get reliable service season after season.
Good to Know
Before installing the new belt, check your pulleys for wear or damage – a bad pulley will eat up a new belt in no time. Make sure the belt sits properly in the pulley grooves and has the right tension. Too loose and it’ll slip; too tight and you’ll wear out bearings. Keep the old belt as a spare or routing reference.
