ABSTRACT:
An improved ride-on rotary lawnmower comprises a cutter device having one or more blades rotating about an axis substantially perpendicular to the ground and contained in a downwardly open casing provided with a rear duct for the discharge of cut grass. The casing of the cutter device of the lawnmower is mounted between front wheels and rear wheels. The bottom of the rear duct of the cutter casing is closed by a wall pivoted about the rear lower side of the duct. A rear grass box is carried either by the casing of the cutting device or by the frame of the lawnmower. A roller is located in the space between the two rear wheels and always in contact with the ground independently from the height from the ground of the cutter casing. The roller occupies the entire space between the rear wheels but does not extend laterally of the rear wheels. The axis of the roller lies in the vertical plane which passes through the axis of the rear wheels and is not displaced to any substantial extent from this axis. The roller may be carried by the frame of the lawnmower or is pivoted at the rear of the cutter casing. In both cases the roller may be loaded by springs connected with the frame of the lawnmower in order to increase the weight on the roller and reduce the weight of rear wheels up to an almost even distribution of weight on rear wheels up to an almost even distribution of weight on the ground. The bottom wall of the casing rear duct straddles the roller, in order to convey grass into the grass box.
