The invention, a horizontally moveable digging/trenching bucket attachment
with boom, for machines (tractor, skid steer . . . ) with pivoting front
end loader allows for a machine with limited capabilities to be used for
various operations through simple detaching of the standard large, wide
bucket and attaching the invention. This invention is unique and
desirable in that it eliminates the need for multiple machines and or
multiple attachments to complete operations that can be accomplished by a
single machine with the attached invention. The invention is comprised of
a horizontally movable digging bucket with steel teeth having a fixed or
adjustable trenching plow and an attachable/detachable boom. Due to the
limitations of a front end loader's motion, the unique design of the
invention will add the capability of horizontal motion for maximum

The present invention is a detachable digging bucket with trencher
and tree boom that can be attached to any machine with a pivoting and
lifting capacity front end loader of a general type as described in U.S.
Pat. 3,231,117 using a quick attach/release plate of a type as described
in U.S. Pat. No. 3,672,521. The invention shown in FIG. 1 can be made up
of but not limited to the following elements: the mounting plate 1 to
which is attached a horizontally moveable digging bucket 2 comprised of
attached hardened 3 teeth 3, a plow plate 4, 4 long flat bars 5, 2 solid
steel pipes 6, 4 hollow short steel pipes 7, 2 hollow longer steel pipes
8, 2 steel angle irons 9, a removable tree boom 10, a large fly bolt 11
to lock invention horizontally in desired place, and a large bolt 12 to
hold the tree boom in place, and end caps 13 on the outer ends of angle
irons 9 to hold the solid steel pipes in place. The tree boom, FIG. 3, is
stabilized by a pivotable bar 15. It is attached by bolts 12a as shown in
FIG. 1 with one end attached to an extension 14 added to the upper hollow
pipe 8 as shown in FIG. 2. Fixed components are best secured together by
means of welding, but may be attached by means of adhesives and/or
screws, nuts, and/or bolts, and/or pin and rod. The teeth 3 are mounted
on the lower open edge of the digging bucket, and the plow may be welded
to the bottom of the bucket and pointed towards the machine or made
adjustable, (FIG. 2). Two flat bars 5 are attached to each lateral side
of the bucket. Each of the bars is attached parallel to the upper and
lower edge of the side, with the bars angling towards the teeth 3 end of
the bucket 2. The 2 hollow longer steel pipes 8 are welded horizontally
to the ends of the flat bars 5 protruding from the closed end of the
bucket 2. The 4 short hollow pipes 7 in FIG. 1 are welded to the ends of
the 2 angle iron pieces 9, which in turn are welded to the front of the
mounting plate 1 along the vertical edges of the plate. Once the large,
wide loader bucket is removed via quick release, the rear of the mounting
plate 1 (facing the machine) can be attached to the machine via means of
quick attach/release or may be permanently affixed (welded) to the
machine. The digging bucket 2 with welded teeth 3 and trenching plate 4
is then connected to the mounting plate (attached to the machine), in the
following fashion: the 2 hollow pipes 8 of the bucket are aligned to the
hollow pipes 7 on the mounting plate and the bucket is in turn attached
to the mounting plate by sliding the solid steel pipes 6 through all
aligned hollow pipes 7 and 8. The solid pipes 6 are secured in place with
the four end caps 13. This method of attaching the bucket to the plate
affixed to the machine ensures maximum strength and flexibility in
positioning (sliding the bucket horizontally), and adjustment of the
digging/trenching attachment. Additionally it allows for ease in
attaching and removing the invention from the machine to allow for
flexibility in use of the machine as well. Although this is the preferred
means of attaching for maximum flexibility and strength, use of the
invention digging/trenching attachment can use other means of attachment
to machine including but not limited to: (a) permanently affixing the
digging/trenching bucket by means of welding, adhesives, and/or screws,
nuts, and/or bolts to the plate; (b) as well as removable attachment by
means of slits on plate and hooks or tabs on bucket to insert into slits.
A large fly nut bolt can be inserted into a hole at the top of the top
long hollow pipe and tightened down into the solid steel pipe to lock
bucket into desired place. The tree boom 10, FIG. 3, is easily added by
slipping it over the center tooth 3, FIG. 2, on the bucket and securing
it as seen in FIG. 1 with nuts and/or bolts 12 and 12a, and/or pins,
and/or clips. Further, this invention can include one or more of the
following: (a) hydraulic pistons for digging bucket pivoting and/or
strength and/or (b) hydraulic pistons for sliding bucket from side to
side. It should further be noted that while steel is the preferred
material for all elements of the invention, particularly A-36 steel,
AR-plate steel, and/or stainless steel, to ensure strength and
durability. Additionally, (c) other materials can be used to manufacture
the invention including but not limited to any other metal or alloy; (d)
dimensions of attachment and bucket can be adjusted to fit machine and
purpose for use; (e) depending on width of the bucket attachment,
additional or fewer teeth can be used for uniform digging and strength.
Particular to this invention is the flexibility it offers owners/operators of machines with pivoting front end loaders (tractors, skid steer loaders . . . ). These machines are designed with a limited capacity and use due to the nature of the large, wide bucket that they are known for. For example, a simple tractor front end loader is limited in it's capabilities to dig holes, trenches, or lift heavy objects--such as landscape trees, without causing damage to the trunk. Various hydraulic attachments and/or other machines such as a backhoe, tree boom, and trencher would be needed to perform those tasks. The invention attachment simply turns a basic tractor or front end loader into a backhoe, trencher, and tree boom; thus resulting in a more cost effective and efficient tool for individuals who require various machines to complete a job. Specifically, the invention digging/trenching attachment allows for digging small or large holes as well as dumping and/or removing of dirt or rock and other materials. The bucket can also serve to dig wide trenches for landscape, excavating, and construction purposes. The teeth on the bucket permit digging in hard ground. Additionally, ropes, chains, or tree straps can be hooked onto the tree boom bar to allow for lifting of heavy material without damage. The plow allows for narrow trenching as needed for example, when laying irrigation pipe. To allow for preference of owner/operator, the mounting plate can be permanently affixed or detachable. Although originally intended as an invention to meet the various needs of landscapers and tree farmers, this invention can clearly assist in construction and excavating purposes as well.
