Evolution of Bullet Santhi
 1994 – First prototype developed by Mansukh bhai
 2000 – Improved version by Mansukh bhai
 2002 – New prototype by GIAN through NID
 2004 – New prototype by GIAN through TePP
 2005 – Improved version with reverse gear by Mansukh bhai
 2008 - Assembled model without bullet chassis by Shailesh bhai
of Bhavnagar
 2008– Shailesh bhai’s model more compact by Mekaran bhai of
Amreli
 2010– 10 HP (Crompton Greaves) assembled model by Rajendra
bhai of Amreli
 2010 – Tall boy model (Handhio) by rashikbhaiFrom dared
bhavnagar
First Model – Developed by Mansukhbhai, 1994
Main Features:
Diesel Bullet motorcycle
Atul Chhakda’s differential (Chhakda is 3-wheeled local transport vehicle)
Chain Sprocket-40 teeth
Remolded Tyres
Use of L-section panel in the supporting frame
Cost: 15,000/- excluding cost of motorcycle
Limitations:
·
L-section panel didn't provide
the required overall strength.
·
40 teeth in sprocket did not
provide required torque.
·
Need presence of second
person to lift the plough while turning
·
No depth control adjustment
facility for plough
·
Slippage problem in wet soil due
to simple tyre
Second Model – Modified by Mansukhbhai, 1995-96
Main Features:
The problem of lesser strength of the L-section was solved by using
channel-section panel.
 Number of teeth of chain sprocket was
increased to 50. This reduced the speed of the vehicle.
 Remolded tyres provided
 New Fiat’s differential
 Depth control facility and mechanical lifting arrangement for plough
 Bent bar for supporting the person standing on tool bar was provided
obviating back breaking posture
Cost: Rs 15,000/- later 20,000/excluding cost of motorcycle
Limitations:
- Sturdy / heavy look
- Lack of ergonomics and aesthetic
consideration
Third Model: Developed by GIAN through NID, 2002
Main Features:
 Diesel Bullet, Chhakda
 Lifting mechanism for the saanti (kind of Hydraulic system)
 Differential of Fiat
 Chain Sprocket-50 teeth
 Traction Tyres (2001)
 Channel -section panel was used in the supporting frame
Limitations:
•
Requires high investment & not
suitable for local production
•
Provision for additional requirements
of farmers are missing ( like provision for
carrying equipments while transportation
from home to farm)
•
Plough needed to be redesigned,
modified design was not acceptable
to the farmers (one can not accept /
change in size of their main equipments
like plough, harrow etc).
•
Low user friendliness.
Fourth Model: by Mansukh bhai in 2004-5
New Features included:
-Gear box with Reverse gear facility
-extension rod on the rear side with which spacing among the rows could
be increased.
Cost: Rs 45,000/-
Limitations:• Cost is very high
• Bullets are not available
easily
Fifth Model: By Saileshbhai from Bhavnagar, 2008
Main Features:
- first assembled model without bullet chasis, new chasis made by Saileshbhai
engine of Chhkada rickshaw ( 7.5 hp)
- gearbox of maruti car\
- Fiat’s differential
Cost: Rs 65,000/Limitations:
Higher RPMs affecting the
balance
Sixth Model: by Mekaranbhai, Amreli, 2008
Main Features:
Similar to the fifth model except :
a) length and thus the turning radius was reduced by changing the
way engine was aligned with differential;
b) the shock absorbers on the front side were replaced by fixed stand
having a single spring in the middle reducing the maintenance costs.
Cost: Rs 85,000/Limitations:
Axel often broke down due to
improper distribution of torque
Seventh Model: by Rajendrabhai, Amreli, 2010
Main Features:
- Assembled model with the new kind of chasis,
-Crompton greaves 10 hp engine,
- Hydraulic system for lifting the attachments,
- Diesel tank was moved behind, making front section much more comfortable
for the driver.
-One additional feature:
different brake system for
each wheel to facilitate
turning.
- Foot accelerator used to
replace hand accelerator.
- A small revision was made
in one of the derivative
models with foot operated
hydraulic.
Cost :1.07 lac with new
engine.
Eighth Model: Handio by Rashikbhai Bhavnagar 2010
Main Features:
-Tall model having differential about 4 to 4.5 feet above the ground and
total height being six feet high.
- It could use two tool bars instead of only one so far. It used 10 hp motor
-Very useful for spraying pesticides in standing crop of cotton.
Cost:
Rs 1.0 lac with old engine and
without hydraulic while with all
new parts and with hydraulic,
it cost about Rs 1.8 lacs. It
was also
Limitation :
Higher fuel consumption.
