DETAILED DESCRIPTION OF THE INVENTION The present invention relates generally to tillers,
and more particularly to tillers utilizing the auger's tilling action. The very usual thing of the
usual cultivator used for the field work before! ! llK Dynamically driven wheel-shaped or
company-line-shaped blade (teeth) t- and a rear-working tiller with a driven wheel. The rotating
blades propel the tillage mt-forward. In fact, the disadvantage of the four solid shoulders of this
type of machine is that the blade is difficult to control and it is too fast for the machine and in the
forward direction to carry the operator's IIIJ II. In order to prevent it from being pulled, EndPage:
2 has an impetus to push forward the obstacle bar. Similar cheaper tillers have front wheels and
rear blades. The wheels are supplied with work to control the forward thrust provided by the
rotating blades. The blades must be shielded to protect the operator and such tillers are simpler
to use than those of the rear wheel type but are extremely expensive. In fact, both of these types
of machines are expensive, and users usually do not buy but rather borrow. Although the auger
type tillage '11 is disclosed in, for example, US Patent Nos. 562.4B5, 2.87 to 850 and 471499.0,
these tillers are different from the conventional tillers described above. It was not U.S. Pat. No.

direction of travel of the cultivator 10 as shown in FIG. 6 and arranged orthogonal to each other.
Each blade has a length generally proportional to the distance from said augerule portion 45 to
provide a substantially conical cutting cone, shown in phantom in FIG.
As shown in FIG. 5, the driven sprockets so # -ff have a transfer pole 52 at the rear end of each
auger shaft 40 and 41. The respective sprocket bosses 52 are arranged opposite to each other
and mounted on their respective axes, with the sprockets 50 and 51 containing rotational planes
spaced from one another by the arrangement of said bosses. Sprockets 50 and 51 provide a
portion of drive assembly 2 o which rotates each axis of auger assemblies 16 and 17. In addition
to these sprockets, the drive assembly 20 comprises a drive sprocket 53 mounted on a motor
shaft 54 located aft through the upwardly extending plate 30 'II. The motor drive sprocket 53
and the auger driven sprocket 51 lie in the same plane and are connected by an endless chain
55. An idler-drive combination sprocket 56 fixed to a rotatable sleeve 58 is mounted on a short
shaft 57 fixed to the plate 50, for example by welding. As best illustrated in FIG. 4a, the minor
axis 57 extends between the plate 50 and the cover 22 and is supported by an opening provided
in the cover 22, for example #i. The combination sprocket 56 has an idler portion 60 and a drive
portion 61 coaxial with it. The idler portion 60'd is in the same plane as the endless chain 55, is

appropriately positioned to engage the Chain EndPage: 4 / b5 and to be wI moved. The driving
part 61 is an auger * W1. It is provided in the same plane as the movement / rocket 50 and is
connected to one sprocket 50 by a second endless chain / 62. The chain 62 drives the auger
shaft 40 in the same rotational direction opposite to the direction of the auger shaft 41. The
mating sprocket auger drive sprockets 50 and 51 for the chain 55 and sprockets 55.51 are
arranged to rotate in substantially the same time, but in opposite directions. In the preferred
embodiment, WIA 1 jl I sprocket 53 is provided with 10 teeth and 6 'drive sprockets 50 and 51
are provided with 5' 0 @ teeth. The idler and drive portion of the combination sprocket 56 is
provided with fifteen teeth, and the wedge sprockets are provided approximately one third of the
distance between the centers of rotation of the sprockets 55 and 51. With such an arrangement,
the auger sprocket is driven at a speed reduced by a factor of 5 relative to the motor drive
sprocket and the cover 21 providing the housing and baffle for the motor 15 has its front end on
the base lower portion 12 Attached by fasteners 64 to the provided lugs 63.
The cover 21 is also attached on each side to a cover 22 which provides the housing of the drive
assembly 20, for example by means of fasteners 6.5. Since the elongated sleeve 42 is connected
to the base 11 and the side silk solid 20 is disposed in the rear direction, the shafts 40 and 41
are spaced apart at a ratio taking into account the entire length of the shaft 43 Supported by The
length between the support bushes is, in this preferred embodiment, greater than the length of
the unsupported portion of the lll shaft projecting forwardly from the sleeve. It will be
appreciated that such a structural arrangement of the parts significantly promotes the stability of
the auger shaft. As shown in FIG. 2 and FIG. 3, the sleeve 42 extends from the base 11 in the
forward direction, but this extension can be increased to further increase the stability.
Furthermore, instead of a continuous sleeve, the support can be provided by a plurality of spaced
apart sleeves with bushes or suitable bearing means at their ends. In addition, with the auger
stem portion-5 at the distal end of each of the shafts 40 and 41, radial blades 46 and 47t- are
provided to provide an excellent cutting cone. The operation of the tiller is smooth, lift the handle
25 and 'W! 4 is triggered by engaging the auger tip with the ground as illustrated in phantom in
FIG. The tilling work starts at the auger tip and goes backwards to the blade that has grown to
the next fang. vf 耘 speed is the auger's lead and auger rotation speed #! Controlled by Rocks are
rolled to the side instead of hitting the blades 46 and 47 and damaging the blades, and the
holding angle with the ground keeps the grade in the cultivated land at a certain predetermined
depth. The part 45 acts as a guiding means and a drafting means at start-up and at work. By
pressing on the 2 +-for a while, the cultivating action occurs, and releasing the press stops the
action of II. The tiller is moved by simply pulling backwards. Since the blades of each auger
assembly are set out of phase with each other, each auger assembly can be placed close to each
other, and any torque is removed by the opposite rotation of each blade to remove any torque.
The result lI 耘 榛 can be handled easily. Honpurosuke # I! In addition to turning work, it can also
be used for drilling and drilling work. The dredging operation is accomplished by first inserting a
portion of the australia 45 into the ground and then tilting the shafts 40 and 41 to a suitable

inclination angle of approximately (+ 0i (60 ′ ′ ′ ′ ′).
Such inclination allows the ground wheels 13 to be lifted and utilize the weight of the apparatus
to facilitate the drilling operation and to pivot the cultivator to the horizontal position, so that
each blade is cut off by cutting the roots or similar. There is a tendency to move objects upward
from below. A large cultivator butterfly Also, as mentioned above, somewhat similar to a kitchen
mixer 71? It is also possible to place EndPage: 5 in a position such that the shafts 40 and 41 are
substantially vertical, so that they can be used in m 轡 and can be used to mix cossicator
additives into soils It is. Also, by providing a variable speed motor, 9 low I I! When it is not
desirable to soil the soil too finely. Encourages soil conditioning capacity. Furthermore, by
rotatably attaching the rear portion of the shaft 4D and -41 to the base portion K, the lateral
force applied to the front portion during operation is resisted by the couple provided by the
mounting of the rear portion. Provide a longitudinal support for the By placing the cover 22
behind the motor 15 and the wheel axis, the center of gravity of the tiller is located behind the
wheel axis, thus providing a means for the rest of the tiller to be inactive.
