In agricultural implements - The plough tool is a very important tool to help break down the soil or control weeds. It is difficult to remove weeds by using tractors and ox in narrow spaced crops like spinach, potato, cauliflower, tomato etc. To overcome this problem, we proposed a new modern Agricultural Machine called E- HARA. It helps to remove the weeds in narrow spaced crops for small farmers in agriculture. E- HARA is to be affordable with low cost and lighter weight to carry. link fo reports: https://bit.ly/2WA4ncd

3. Abstract
 In agricultural implements - The plough tool is a very important
tool to help break down the soil or control weeds. It is difficult
to remove weeds by using tractors and ox in narrow spaced
crops like spinach, potato, cauliflower, tomato etc.
 To overcome this problem we proposed a new modern
Agricultural Machine called E- HARA.
 It helps to remove the weeds in narrow spaced crops for small
farmers in agriculture. E- HARA is to be affordable with low cost
and lighter weight to carry.
 This Project includes the Modelling of E-HARA.

9. Cultivator is a machine that is used to
prepare soil fertility and to kill weeds.
Which are not Harmful to the
Environment.

10. Components using
 Four main components
Controller

11. Hub Motor
 Rotatory electrical motor.
 It fixes on wheel rim.
 Converts Electrical energy to Mechanical energy.

12. Controller
 Controls the hub motor.
 Adjust the speed.
 Forward and backward operations.

13. Li-ion Battery
 High efficiency
 Fast Charging
 More Life span

14. Plough Tool
 Special tool to bury weeds easily

24. Final Model

25. STEP 1
 Fabricating the frame with required dimensions using
welding operation.
STEP 2
 Inserting the hub motor in 26” wheel rim.
STEP 3
 Attaching of wheel, controller, throttle, battery to the
frame.
STEP 4
 Fitting the Plough tool to the frame with required Angle.
Process of Fabrication

Materials Used in E-Hara

27.  Availability of price
 Less maintenance
 Careful cutting of weeds in narrow spaced crops
 Easy to carry anywhere
 No pollution emits
Advantages
Disadvantages
 Suitable only for tasks on limited, small areas
 Not automatic

28.  we strongly believe that after fabrication e-hara will
affordable for all kind of farmers.
 Its reduces the time & man power.
 E-Hara will satisfy the partial thrust of agriculture.
Future Scope

29.  Based on the overall performance of e-hara, we can definitely say that
the project will satisfy the need of small-scale farmer, because they are
not able to purchase costly agricultural equipment. But our e-hara
coming with affordable price range for every small-scale farmer.
 The machine required less man power and less time than compared to
traditional methods, so if we manufacture it on a large scale its cost
gets significantly reduce and we hope this will satisfy the partial thrust
of Indian agriculture.
 So, in this way we solve the labour problem that is needed for today’s
farming in India.
