dllawson, thanks for the input! I seem to see John Deeres, Lesco, and toro prolines for sale in the $800-$1,500 range. Obviously they're all well used, but for my needs I think I could get my money's worth out of something like that. Is there a weight limit on the velke? I'm 6'6" 260, so I'm a little worried I may be a bit much for the velke.
Can anyone give me suggestions of what I should check out on a used walk behind? Any usual suspects that are prone to breakage?
