BACKGROUND OF THE INVENTION
[0002] The Agriculture is the backbone of Indian economy as it
provides direct employment to the working people. Being the
largest source of employment and income to millions of people,
it also provides a vast market for the proposed industrial
product. Factors such as time saving, efficient input application,
transportation of farm inputs, and reducing drudgery stimulate
demand for farm machines. The growing shortage of agricultural
labor and rising wage rates also contribute to the reasons for
the accelerated mechanization of farm operations. The
development and mass production of multi-utility mechanized
devices to suit the requirements of farmers is crucial for the
growth of mechanization of agriculture in India. Hilly landscapes
(such as in Himachal Pradesh) require to have simple, powerful
and mechanized solution for agriculture. Due to hilly area and
3
small tillage areas, existing heavy machines are not applicable
in the farms for agriculture. Therefore, there is need of a low
cost and light weight power tiller to fulfill the agricultural
requirement for the cultivation of different crops in hilly as well
as plain areas having hard surfaces.
[0003] Prior art D1: GB2292059A provides one such technique
for tilling. However hand-held power tiller disclosed in D1
includes two independently driven tines which, in use, are
arranged to rotate in opposite senses about generally vertical
axes. This provides a more controllable tiller than conventionally
available. Each of the tines has forks which are angled to drag
the tiller down into the earth being tilled. Each set of tines is
driven by an electric motor which may be powered by batteries
stored in the handle. However, the technique disclosed in D1 is
not suitable for tilling in hilly areas and hard surfaces.
[0004] Prior art D2: CA 2184396 A1 discloses a tilling shaft for
a power tiller that includes: an insertion portion formed on a
distal end side of the tilling shaft projecting from a power
transmission case of the power tiller, the insertion portion
having a substantially circular cross section; a polygonal shaft
4
portion formed on a proximal end of the tilling shaft adjacent
the insertion portion; and a tapered portion formed between the
polygonal shaft portion and the insertion portion such that a
diameter of the tapered portion is gradually increased from a
distal end side toward a proximal end of the tapered portion.
The diameter of the insertion portion may be identical to the
diameter of an imaginary circle inscribed within the polygonal
shaft portion. Alternatively, the diameter of the insertion portion
may be slightly larger than the diameter of the imaginary circle,
and a plurality of ribbon-shaped supporting surfaces are formed
on the insertion portion in such a manner as to be flush with
respective side surfaces of the polygonal shaft portion.
[0005] Prior art D3: US7874375B2 discloses an attachment for
a conventional, walk-behind power tiller for forming seed rows
and adjacent furrows wherein an auger disposed perpendicularly
to the seed row being formed has a larger diameter at its
proximal ends and a smaller diameter at its central, inner end.
The auger is rotated using power derived from the tiller to which
the novel seed row forming apparatus is attached. In operation,
the larger diameter outer portions of the auger dig a furrow and
5
move the disturbed soil inwardly along the diminishing diameter
of the auger, thereby depositing the soil from each side of the
auger into a central berm or seed row. The apparatus provides
seed row-forming capability for use with small rotary tillers and
provides minimum soil tillage while readily forming planting
rows
[0006] D1-D3 lacks wheels and moving it for tilling in hilly ares
will be difficult. Further, functioning of D1-D3 is based on
rotation of blades, which causes high vibration and energy loss.
Therefore there is a need for an efficient, simple, low cost,
energy-efficient and easy-to-move potable power tillers for
tilling in agricultural fields, even in hilly areas.
[0007] Thus, in view of the above, there is a need in the
industry to address the aforementioned deficiencies and
inadequacies.
[0008] Further limitations and disadvantages of conventional
and traditional approaches will become apparent to one of skill
in the art through comparison of described systems with some
6
aspects of the present disclosure, as outlined in the remainder
of the present application and with reference to the drawings.

DETAILED DESCRIPTION OF DRAWINGS:
[0019] In overview, embodiment of the present disclosure are
concerned with a potable power tiller (100).
[0020] Referring to Figure 1,2 and 3, a potable power tiller
(100) is represented in accordance with an embodiment of the
present invention. The potable power tiller (100) for plough
operation in agricultural fields comprises: a chassis (101) to
hold an engine (102) and a fuel tank at a front of the chassis
(101). The chassis (101) also holds a pulley clutch (108), a
10
drive motor in a housing, a drive axle and a hydraulic disc brake
system. Two wheels (103) mounted with grooved tires attached
at two ends of the drive axle. A handle mounting bracket
attached at a rear of the chassis (101). A handle with a first
handle grip (105a) and a second handle grip (015b) attached a
distal end of the handle mounting bracket. A brake lever
assembled at the first handle grip to apply brake to the potable
power tiller (100). A clutch lever assembled at the second
handle grip (105b) to to engage and to disengage the pulley
clutch (108) with the drive axle. A tiller bracket (104) mounted
at the rear of the chassis (101). A plough attachment
comprising one or more plough blades mounted on the tiller
bracket.
[0021] A user holds the two handle grips (105a, 105b) to
control the direction of movement of the potable power tiller
(100). The user applies brake to the two wheels (103) by
pressing the brake lever (106) interconnected with the disc
hydraulic brake system. The braking system employed in the
potable power tiller (100) is disk brake using oil cooled system.
Using a braking system reduces ploughing time and load on the
11
potable power tiller (100) when using brakes while turning.
Moreover, most of the ploughing equipment are operated with
tractors and lifting them uses a manually operated lever. In
addition, the hydraulic disk brake system has firm advantage
over other braking systems. This type of system generates less
amount of heat for the same braking effort thus, increasing the
life of potable power tiller (100). The system is simple as it has
fewer moving parts than drum and leather brake system
furthermore the braking performance is less likely to be affected
by dirt, water, or rust contamination. Maintenance is simple and
cheaper as access to the calliper is easy.Disc brakes represent a
better value to the consumer in that they have a lower owning
cost over the expected life of the equipment.
[0022] The engine (102) drives the two wheels (103), the user
holds the handle grips with two hands and walks behind the
potable power tiller (100), and the plough blades forced to
penetrate into soil at an acute angle less than 200
to break the
soil and to cut furrows in the soil.
[0023] In an exemplary embodiment of the present invention,
the potable power tiller (100) comprises a switch to either
12
switch ON or switch OFF the engine (102), which is mounted
near the first hand grip (105a) or the second hand grip (105b).
The two tires (103a) of the potable power tiller (100) comprise
a plurality of protrusion. Further, a mud flap (107) is mounted
above each of the two tires (103a) of the potable power tiller
(100) to protect tires (103a) from loose debris, mud, rocks, etc.
[0024] The potable power tiller (100) weighs around 70-80 Kg
which is far less than disc ploughers or rotary plough which are
used more often. Elderly people and women form a significant
portion of the population involved in agriculture and the light
weight of this attachment makes it easy for them to use. Also,
considering the poor scope for industrialization in mountains and
perspective of rural livelihood, agriculture remains an important
sector for livelihood and economic growth. The hill agriculture
has its own unique characteristics and that the growth potential
of hill agriculture has remained under-exploited due to various
mountain specifics like undulating topography, lack of system
specific technologies and under developed supporting
institution. Considering the cost benefits and portability and
light-weight of the proposed equipment, it is more suitable to
13
run in hilly areas. A significant reduction in price was achieved
when compared to other attachments working at the same
capacity.
[0025] Furthermore, the ploughing in conventional tillage using
rotary or disc ploughers is costly and difficult as rotary tillage
has the disadvantage of not working properly in hard soil.
Moreover, there is major soil erosion, high loss in soil moisture
and highest fuel and labour costs. The fields are left rough and
cloddy and the are not found suitable for covering surface trash.
Constant cleaning is required when not in use and earth sticks
readily to them when operational. Blunt blades require regular
sharpening and they have to be constantly checked for loose
nuts and bolts. Almost all of these shortcomings have been
overcome in the potable power tiller (100) disclosed, making it
favourable for use when compared to the traditional equipment.
[0026] Modifications to embodiment of the invention described
in the foregoing are possible without departing from the scope
of the invention as defined by the accompanying claims.
Expressions such as “including”, “comprising”, “incorporating”,
“consisting of”, “have”, “is” used to describe and claim the
