Abstract: A towed mower having a rectangular frame and a pair of diagonally related blade spindles is described. The mower of the present invention includes both a wide side and a narrow side and an associated shroud assembly. A pair of blade spindles each carry a rotary mower blade covered by the shroud assembly. The mower may be used in either a wide mode or a narrow mode and the preferred embodiment provides an arrangement of parts for easy retorientation between the wide and narrow modes. Separate outlet doors are provided for both the wide side and the narrow side on the shroud assembly and hitch-engaging posts are disposed at each corner of the mower frame to engage a pair of wheel suspension arms and a pair of hitch-engaging brackets. The hitch-engaging brackets and the wheel suspension arms are secured to the posts in a manner which allows ready removal and/or pivoting of the suspension arm or the hitch-engaging bracket so that the mower may be re-oriented from the wide mode to the narrow mode and vice versa.
