I am in the market for a durable 21" mower that will be used primarily for my 1/3 acre lawn. I've looked at the John Deere JX75 and 85 (being discontinued). I am really interested in the Metro 21, but need some additional info. I will primarily bag, but want the mower to also be a quality mulcher at times. 1. How many gears does the Metro 21 use. What are the speeds for each gear? 2. What is the blade tip speed? 3. Does the trivantage deck bag and mulch well? Are different blades needed for each application? I don't mind changing the blades if I have to. I have heard that the deck does not have the toro kickers. Can you confirm? 4. Can I still get the Metro w/ the Kaw. engine? Thanks.
