A convertible sulky is interchangeable between stand-up and sit-down configurations so as to allow a mower operator to operate the mower from either a standing or seated position behind the mower. The convertible sulky comprises an H-shaped support wheelbase frame, to opposite legs of which a pair of wheel-mounting columns are affixed. Attached to the H-shaped support wheelbase frame member is a T-shaped mower attachment frame, having a central leg, an upper end of which is inclined forwardly H-shaped support wheelbase frame for attachment with the rear of the mower, by means of a ball-hitch fixture. A pair of generally L-shaped foot plates are secured to the frame structure formed by the T-shaped mower attachment frame and the H-shaped support wheelbase frame. A removable seat attachment comprises a column member having a first leg portion at a lower end thereof, sized for insertion into the second, lower end of the central leg of the T-shaped mower attachment frame, and a second leg portion at an upper end thereof. The second leg portion of the seat attachment extends horizontally from the column portion and receives one leg of a U-shaped seat spring member, to which a seat is attached.
