Abstract

A combination machine for trenching, for forming the edge of a bed, and for laying and burying tubing, cable, piping, and the like. The machine includes steerable caster wheels mounted on the rear of the machine which, together with a single front wheel, allow for a tight turning radius when using the machine. The machine also includes a blade height adjustment which allows for the trenching or edging blade depth to be readily adjusted in a substantially infinite variation. An edging blade is provided which when used with the machine forms a groove at the bed'"'"'s edge for the laying of irrigation lines, or lines for herbicide, pesticide, and/or fertilizer for use in connection with the bed.

Claims

1. A soil bed edge forming machine for use in creating defined mounded soil borders for defining landscaping beds, the machine comprising:

a frame;

a motor and wheels connected to said frame;

a digging blade;

said motor being drivingly connected to said digging blade; and

an elongated digging depth adjustment member connected to said digging blade;

said adjustment member defining a central axis and being threaded and rotatable about said central axis for allowing selective digging depth adjustment of said digging blade into the soil.

2. A soil bed edge forming machine as defined in claim 1, wherein at least two of said wheels are caster wheels.

3. A soil bed edge forming machine as defined in claim 1, wherein said frame includes a front portion and a rear portion and wherein said wheels include a single wheel mounted on said front portion and two caster wheels mounted on said rear portion of said frame.

4. A soil bed edge forming machine as defined in claim 1, further including a bed edging blade, comprising:

a base plate and an end plate;

at least two arms connected to said base plate and said end plate, said arms being acutely angled with respect to said base plate; and

outwardly extending digging fingers connected to said arms.

5. A soil bed edge forming machine as defined in claim 1 wherein the axis of rotation of said digging blade is in generally vertical alignment with at least one of said wheels.

6. A bed edging blade for attachment to a shaft of a bed edging machine for use in creating mounded soil borders for defining landscaping beds, comprising:

a base plate;

an end plate separate from said base plate;

at least two arms connected to said base plate and to said end plate, said arms being acutely angled with respect to said base plate, and said arms holding said end plate outwardly from said base plate; and

outwardly extending digging fingers connected to said arms.

7. A bed edging blade as defined in claim 6, wherein at least one of said digging fingers includes a carbide digging blade.

8. A bed edging blade as defined in claim 6, further comprising said digging fingers being inwardly curved along their length.

9. A bed edging blade as defined in claim 6, wherein said at least one of said two arms includes a digging finger having a forward cutting edge acutely angled with respect to said base plate.

10. A bed edging blade as defined in claim 6, wherein said base plate includes at least one outwardly extending digging finger for digging a groove below the depth of the bed edge.

11. A bed edging blade as defined in claim 6, wherein said base plate includes at least one outwardly extending digging finger and a brace portion connected to and extending adjacent the major portion of the length of said digging finger.

12. A bed edging blade as defined in claim 6, wherein said blade is of a generally pyramid shape.

13. A method for creating defined mounded soil borders for defining landscaping beds and for installing an elongated member in the ground, the method comprising:

providing a bed edging machine having a combination bed-edging and groove-forming digging blade;

moving the machine rearwardly to form a trench of a first depth and a mounded bed edge in the soil adjacent only one side of said trench with said bed-edging and groove-forming digging blade;

simultaneously forming a defined groove in the soil at a second depth below said trench with said bed-edging and groove forming digging blade, said second depth being deeper than said first depth; and

inserting an elongated member into said groove at said second depth.

14. A trenching machine for placement of cable, tubing, wire, and pipe in the soil, comprising:

a frame;

a motor and wheels connected to said frame;

a trenching blade;

said motor being drivingly connected to said trenching blade, and said trenching blade being operable to dig a trench in soil when the machine is moved rearwardly;

a holder connected to said frame for holding the elongated material;

a guide connected to the frame for guiding the elongated material into the ground;

a delivery chute associated with said trenching blade for delivering soil to a trench dug by said trenching blade to backfill the trench and bury the elongated material; and

a first wheel mounted on said front portion of said frame and two caster wheels mounted on said rear portion of said frame, wherein the axis of rotation of said trenching blade is in generally vertical and parallel alignment with the axis of rotation of said first wheel, for allowing the trenching machine to be readily steered as it is moved rearwardly.

15. A machine as defined in claim 14, further comprising a foot member connected to said guide.

16. A machine as defined in claim 14, further comprising a foot member connected to said guide, and wherein said foot member is pivotally attached to said delivery chute.

17. A machine as defined in claim 14, further comprising a spool holder for supporting a spool of the elongated material.

18. A machine as defined in claim 14, further including a bed edging blade attachable to said motor, comprising:

a base plate and an end plate;

at least two arms connected to said base plate and said end plate, said arms being acutely angled with respect to said base plate; and

outwardly extending digging fingers connected to said arms.

19. A soil bed edge forming machine for use in creating defined mounded soil borders for defining landscaping beds, the machine comprising:

a frame defining a front portion and a rear portion;

a motor connected to said frame;

a soil bed edging blade;

said motor being drivingly connected to said soil bed edging blade, and said soil bed edging blade being operable to form a trench and a mounded soil bed edge on only one side of said trench when the soil edge forming machine is moved rearwardly; and

a first wheel mounted on said front portion of said frame and two caster wheels mounted on said rear portion of said frame, wherein the axis of rotation of said soil bed edging blade is in generally vertical and parallel alignment with the axis of rotation of said first wheel, for allowing the soil edge forming machine to be readily steered as it is moved rearwardly.

20. A soil bed edge forming machine for use in creating defined mounded soil borders for defining landscaping beds, the machine comprising:

a frame defining a front portion and a rear portion;

a motor connected to said frame;

a soil bed edging blade;

said motor being drivingly connected to said soil bed edging blade, and said soil bed edging blade being operable to form a trench and a mounded soil bed edge on only one side of said trench when the soil edge forming machine is moved rearwardly;

a first wheel mounted on said front portion of said frame and two caster wheels mounted on said rear portion of said frame, wherein the axis of rotation of said trenching blade is in generally vertical alignment with said first wheel for allowing the soil edge forming machine to readily be steered as it is moved rearwardly; and

an elongated digging depth adjustment member connected to said soil bed edging blade;

said adjustment member defining a central axis and being threaded and rotatable about said central axis for allowing selective digging depth adjustment of said digging blade into the soil.
