Evolution of Bullet Santhi1994 – First prototype developed by Mansukh bhai2000 – Improved version by Mansukh bhai2002 – New prototype by GIAN through NID2004 – New prototype by GIAN through TePP2005 – Improved version with reverse gear by

Mansukh bhai2008 - Assembled model without bullet chassis by

Shailesh bhai of Bhavnagar2008– Shailesh bhai’s model more compact by

Mekaran bhai of Amreli2010– 10 HP (Crompton Greaves) assembled model

by Rajendra bhai of Amreli2010 – Tall boy model (Handhio) by rashikbhaiFrom

dared bhavnagar

First Model – Developed by Mansukhbhai, 1994Main Features:

Diesel Bullet motorcycleAtul Chhakda’s differential (Chhakda is 3-wheeled local transport vehicle)Chain Sprocket-40 teethRemolded TyresUse 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 Saileshbhaiengine 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.
