Abstract

With a limited separating spacing immediately upstream of a mowing implement rotating in a horizontal plane, a lawnmower has an upward extraction implement rotating in the same direction as the advance direction about a horizontal transverse axis and which is located in a common casing, but in a separate casing chamber. The upward extraction implement is disengagingly driven by means of a gear by the drive motor of the mowing implement and is essentially located between the front wheels, which are vertically adjustable for the joint setting of the working height of the two implements. Thus, it is possible to in each case separately and also jointly and simultaneously work with the two implements, so that numerous use possibilities exist.

A lawnmower (1) comprising:

a chassis (2) determining a running plane (10) and a main operational advance direction (16) of an operational advance motion;
at least two working devices (6,7) including a mowing device (7) and a ground working device, said working devices (6,7) providing working implements (8,9) including at least one mowing implement (9) and at least one ground working additional implement (8) to operationally perform positively driven motions, said working implements (8,9) being at least partly separately mounted and determining working areas, and a drive means (20) for driving at least one of said working implements (8,9), wherein at least two of said working implements (8,9) of at least two of said working devices (6,7) are commonly integrated on said chassis (2), at least one of said working implements (8) providing at least one of said additional implement (8) positively driveable by said drive means (20) including at least one drive arrangement, common with working tools (70) of at least two of said working implements (8,9) being reciprocally rotational and arranged behind one another, in directly adjacent succession with respect to said advance direction (16) in a view on said running plane (10) and in an operational state, a clear distance between orbits of working tools of said mowing implement and of said additional implement being smaller than a working radius of an orbit of said additional implement (8), said chassis (2a)including ground supporters (4a,5) defining lateral running tracks, said additional implement (8a) extending between said running tracks and being located in a casing chamber (37a)separate from said mowing implement (9a).
