Does anyone have experience with a walker 42-inch mulching deck of the 2004 series (older decks should have same design). The deck style was changed in about 2006, so I am not asking about the newer style. I found a like new 2004 mulching deck (used probably 5 hours) without the carriage assembly. The price is $500 which I think is very reasonable, but I want to know how the deck performs on bermuda and zoysia. They will let me try the deck out, but a single trial can't tell me enough about the deck. Is there anyone who has used one for a long enough period to give me the pros and cons. Obviously if Walker changed the design, they must have thought something needed improving.
