Abstract

The invention relates to a landscape conditioning assembly for use in grooming and cleaning dirt and grass sufaces, such as a baseball field. The assembly includes frame means (12) defining a plane to be moved over the landscape. The frame means (12) includes first and second side rails (14, 16) and first and second crossbar supports (18, 20) extending therebetween. First and second cutting blades (26, 28) extend between the first and second side rails (14, 16) and are adjustably mounted to the first and second crossbar supports (18, 20) by adjustment means for selectively adjusting the distance the first and second cutting edges (34, 36) extend below the plane to establish any one of various depths of cut. The assembly also includes a fixed cutting blade (44) which extends between the first and second side rails (14) and is fixedly secured thereto ahead of the adjustable cutting blades.

Claims

1. A landscape conditioning assembly for grooming the landscape of a soil surface, said assembly comprising;

a frame means (12) defining a plane to be moved over the soil, said frame means (12) including first and second side support rails (14,

     16) and first and second cross bar supports (18,

     20) extending laterally across said frame means (12) and between said first and second side rails (14,

     16) and fixedly secured thereto, said first and second cross bar supports (18,

     20) disposed in spaced parallel relationship with respect to each other and spacing said first and second side rails (14,

     16) so as to define said plane, a first cutting blade (26) extending laterally across said frame means (12) inclined relative to said plane for presenting a first cutting edge (34) to engage the surface, said assembly characterized by first adjustment means adjustably mounting said first cutting blade (26) to said first cross support (18) for selectively adjusting the distance said first cutting edge (34) extends realative to said plane to establish any one of various depths of cut, said first cross bar support (18) including a packing portion (58) disposed on the underside thereof and inclined downwardly relative to said plane so as to be positioned for engagement with the surface for packing soil as said assembly is moved over the soil surface, said frame including side rail bumper guard (80,82) secured intermediate the ends of each first and second side rail (14,

     16) for providing additional support to said side rails (14,

     16) and for preventing said frame (12) from becoming snagged on fences and the like.

2. An assembly as set forth in claim 1 further characterized by said assembly including a second cutting blade (28) extending laterally across said frame means (12) for presenting a second cutting edge (36) to engage the soil and including second adjustment means adjustably mounting said second cutting blade (26) to said second cross bar support (20) for selectively adjusting the distance said second cutting edge (34) extends beneath said plane to establish any one of various depths of cut.

3. An assembly as set forth in claim 2 further characterized by said assembly including a fixed cutting blade (44) extending laterally across said frame means (12) and fixedly secured thereto for presenting a third cutting edge (46) to engage the soil.

4. An assembly as set forth in claim 3 further characterized by said fixed cutting blade (44) disposed at a first position preceding said first and second cutting blades (26,28) and in spaced relationship with respect to said first cutting blade (26).

5. An assembly as set forth in claim 4 further characterized by said first and second adjustment means including blade-mounting posts (30) disposed on said crossbar supports (18, 20) and alignment slots (32) disposed on said first and second cutting blades (26, 28), said blade-mounting (30) posts and said alignment slots (32) disposed relative to each other such that said first and second cutting blades (26, 28) may be adjustably mounted to said first and second crossbar supports (18, 20) such that the distance said first and second cutting edges (26, 38) extend below said plane may be selectively adjusted to achieve various depths of cut.

6. An assembly as set forth in claim 5, further characterized by said fixed cutting blade (44) and said second cross bar support (20) including a downwardly extending packing portion (58) disposed on the underside thereof for packing soil as said assembly is moved over a soil surface.

7. An assembly as set forth in claim 6 further characterized by said assembly including a stone receptacle means (70) disposed between said cutting blades (44, 26) and said spreader bar (66) for receiving material which passes over said cutting blades (44, 26) and said spreader bar (66) and for allowing material made up of elements smaller than a predetermined size to pass through said receptacle (70) while retaining larger sizes therein.

8. An assembly as set forth in claim 7 further characterized by said assembly including weight support means (72) extending between said first and second cutting blades and parallel to said side rails (14, 16) for supporting additional weight.

9. An assembly as set forth in claim 8 further characterized by said crossbar support (18, 20 including a pair of ears (22) and a beam (24) mounted to and extending between said pair of ears (22), said ears (22) being adapted for mounting said crossbar supports (18,20) to said frame means (12), said beam (24) presenting a mounting surface (24) inclined at an angle with respect to said plane of said frame means (12).

10. An assembly as set forth in claim 9 further characterized by, said side rails (14,16) including inwardly extending ledges (62) disposed along said rails (14,16) and parallel to said plane of said frame means (12), said ledges (62) interrupted at predetermined points to present gaps (64) to facilitate the extension of said cutting blade (26) therethrough and below said plane of said frame means (12).
