Abstract

A landscape leveling and raking apparatus has a frame, a handle protruding upwardly from the frame, a rake pivotally coupled to the frame to protrude downwardly and rearwardly therefrom, a screed fixed to the frame forwardly of the rake, a plurality of tiller blades rotatably mounted along a forward, open end of the frame, a motor which rotatably drives the tiller blades, and a mechanism for raising or lowering the tiler ,blades relative to the frame. As the blades rotate, they till the soil and propel the apparatus forward. The frame is open along its front edge. This allows soil to accumulate within the frame as the apparatus moves forward. The soil gradually escapes from the frame by passing beneath a screed fixed along the lower rear edge of the frame. The screed levels the soil before it is raked by the tines of the rake.

Claims

1. Landscape leveling and raking apparatus for finish raking of soil spread on a prepared base, said apparatus comprising:

(a) a frame having;

(i) an open forward end;

(ii) downwardly projecting side walls;

(b) a forwardly extending handle protruding upwardly from said frame;

(c) a rake pivotally coupled to said frame to protrude downwardly and rearwardly therefrom;

(d) a screed fixed to said frame forwardly of said rake;

(e) a plurality of tiller blades rotatably mounted along said forward, open end of said frame;

(f) drive means for rotatably driving said tiller blades; and

,

(g) means for raising or lowering said tiller blades relative to said frame.

2. Apparatus as defined in claim 1, further comprising means for adjusting the angle of inclination of said rake relative to said frame.

3. Apparatus as defined in claim 2, wherein:

(a) said tiller blades are fixed on a rotatable shaft extending along said forward, open end of said frame; and

,

(b) said drive means further comprises a motor mounted on said frame and coupling means for drivingly coupling said motor to said shaft.

4. Apparatus as defined in claim 3, wherein said means for raising or lowering said tiller blades relative to said frame further comprises:

(a) first and second link arms respectively rotatably mounted on opposed ends of said rotatable shaft and pivotally connected to opposed sides of said frame;

(b) a second shaft extending parallel to said rotatable shaft;

(c) third and fourth link arms respectively pivotally connected between opposed ends of said second shaft and said first and second link arms;

(d) a first lever pivotally connected to said handle; and

,

(e) a height adjusting rod having one end pivotally connected to a fifth link arm fixed to said second shaft and having an opposed end connected to said first lever.

5. Apparatus as defined in claim 4, wherein said means for adjusting said angle of inclination of said rake further comprises a second lever pivotally connected to said handle;

and, a rake adjusting rod having one end pivotally connected to said rake and an opposed end connected to said second lever.

6. Apparatus as defined in claim 5, further comprising at least one rotatable wheel mounted on said frame for pivotal movement of said wheel between a storage position in which said wheel remains clear of the ground, and a transport position in which said wheel contacts the ground.

7. Apparatus as defined in claim 6, further comprising brace means for bracing an operator'"'"'s foot during movement of said wheel between said storage and a transport positions.

8. Apparatus as defined in claim 7, further comprising biasing means for assisting movement of said wheel into said storage position and for retaining said wheel in said storage position.
