Abstract
A lawn mower including a deck having an inner surface forming a cutting chamber, a cutting blade disposed within the cutting chamber, a drive motor for rotating the cutting blade within the cutting chamber, and a separate wear-resistant liner removably attached to the deck and covering at least a portion of the inner surface of the deck. The liner conforms to the shape of the deck and is formed of a wear-resistant plastic material which substantially increases the life of the deck under abrasive conditions such as sandy soil. Other embodiments are disclosed wherein an integral layer of wear-resistant plastic is formed directly on the inner surface of the deck and wherein a separate rigid liner having an integral layer of wear-resistant plastic formed directly thereon is removably attached to the inner surface of the deck. The wear-resistant plastic is preferably a urethane polymer or a polyurethane elastomer.
