Let J-Thomas turn your walk-behind mower into a stand-on mower with our sulkies/velkies.  We offer one wheel and two wheel sulkies fitting a wide variety of applications.  If you are a lighter operator and don't mind a visible tire track in the middle of your stripe, we recommend a one wheel sulky.  If you are looking for a more stable sulky with two wheels that line up with the mower, we recommend a two wheel sulky.
