We run 3 Walker mowers 2 are 26EFI all have large 9.5 hoppers and all options. We also run Z-Masters and Walkbehinds. In any area the Walker is by far all our employees favorite and ours. Yes the z's are good but they lack the quick tight steering and mobility the Walkers have, they are also the best at spring and fall cleanups, we can fit 4 Walkers on a 18' trailer without lifting the decks up! and you can lift the deck up in 10seconds for cleaning, servicing and blade changes take only minutes.You can switch from a 42" to a 62" deck in minutes!!!! If you have open -open areas a z will out do it but for DETAIL-DETAIL and tight areas its the best!
