I don't own one, but I got the brochure in the mail. From what I read, they have fixed decks and a gear driven. They look cheap i comparison to most other mowers, but that must be the "simplicity" of the Walker engineering. One nice thing is you can use any of their decks up to 56". I noticed that the design of the Walker ZTRs is to send the grass to the middle of the deck(blades designed to direct it this way) so it can be bagged. Does this cause the side discharge capabilities to basically suck, especially with their 74" deck?
