Abstract
Abstract An apparatus for use in lawn and garden maintenance, in which a chassis having a pair of axially aligned and independently operable drive wheels carries a central reel mower mounted with the rotational axis of the mower and the drive wheels lying in the same vertical plane. A pair of outer reel mowers may be mounted on the chassis on each side of the path of the central reel mower. A cultivator mounted on a chassis with a pair of axially aligned drive wheels has the frame of the cultivator projecting laterally and aligned with the axis of the drive wheels, the frame of the cultivator being preferably extensible. A lawn trimmer swivelly mountable vertically on a motor driven chassis comprises an articulated arm with a trimming device mounted on the free end of the arm, the arm comprising two pivotally joined parallelogram units and a handle for manipulation of the arm. A blower mounted on a wheeled chassis has an inlet duct which is adaptable for the attachment of an intake nozzle with the outlet nozzle of the blower being directable into a collection container also mounted on the chassis.
