The drive wheels are spring-loaded to follow the ground contour, and the height of the interchangeable units with respect to the vacuum is adjustable. A moveable shutter is interposed between the mower and brush units and the vacuum intake to regulate air flow. The prime mover drives an axial-intake fan having an unusual rotor design, with two pairs of diametrically opposed blades perpendicular to the back plate, each of the pairs being tangent to its own circle concentric with the shaft of the fan, the two circles being of differing diameters. The radially inner corner of each blade away from the back plate is bevelled.，下面是Garden grooming machine and rotor therefor专利的具体信息内容。

权利要求

1. A garden grooming machine, comprising a wheeled chassis, a vacuum sweeper for garden materials mounted on said chassis and having an elongate intake slot disposed adjacent and generally parallel to ground level, a reel-type lawn mower mountable on said chassis adjacent to and ahead of said intake slot for projecting material clipped by said mower tangentially toward said slot, a prime mover mounted on said chassis and connectable to said sweeper, said mower and the wheels of said chassis for propelling same, said mower being demountable from said chassis, and a rotary brush member mountable on said chassis in place of said mower and connectable to said prime mover for rotation thereby, so that material swept from the ground surface is projected tangentially of said brush member toward said intake slot.

2. A garden grooming machine, comprising a wheeled chassis, a vacuum sweeper for garden materials mounted on said chassis and having an elongate intake slot disposed adjacent and generally parallel to ground level, a reel-type lawn mower mountable on said chassis adjacent to and ahead of said intake slot for projecting material clipped by said mOwer tangentially toward said slot, a prime mover mounted on said chassis and connectable to said sweeper, said mower and the wheels of said chassis for propelling same, and a shutter member disposed between said mower and said intake slot adapted to regulate the amount of air passing from the vicinity of said mower into said intak slot.

3. A garden grooming machine as described in claim 1 and wherein said shutter member comprises a longitudinal section of a circular cylinder oriented with the axis of the cylinder generally coaxial with the axis of the reel of said mower, said shutter member being journaled on said mower for movement along the path of a portion of the circumference of a circle substantially concentric with the axis of the reel of said mower.

4. A garden grooming machine as described in claim 1 and wherein the elevation of said brush member with respect to said chassis is adjustable.
