Blow the Mower Deck Clean
You might think that the belt guards on top of a mower deck protect the belts and pulleys from grass clippings, dirt and other debris. But just the opposite is true. The spinning belts and pulleys suck in debris and the guards trap it inside. Then it swirls around, grinding away at the pulley surfaces and tearing up your belts. Once a pulley wears, it will quickly chew up every new belt you put on. Avoiding having to purchase expensive belt and pulley replacements is easy; just blow the deck off with an air compressor or leaf blower after every third or fourth mowing.
