swing low, sweet tractor

mon, 04 mar 2013 12:01:24 +0000

the dragon is an electric vehicle to serve as a personal tractor for farm workers doing hand work in the field. it provides a low seating position on a special seat to enable comfortable access to low growing crops. it is narrow such that it fits in a row space wide enough for a human worker. it is stabilized by the effects of a wide hard wheel that provides a stabilizing wide stance, while the wide and large wheel provides a large footprint that enables highly efficient operation in soft dirt. this is an ideal electric vehicle application where inexpensive lead acid batteries are sufficient for its low speed operation.

dragon multipurpose farm vehicle

sat, 11 aug 2012 07:00:57 +0000

the dragon tractor is a farm vehicle that has many applications and intends to provide easier access to crops as well as more comfort for the operator. the dragon can perform farming tasks including planting, cultivating, inspecting, pruning, and harvesting. in addition, the tractor can handle a variety of crops thanks to extra tools and adapters that would attach to the tractor depending on the crop. one key advantage of the dragon is its low, thin profile, allowing the operator to move the tractor in between closely-planted crops. now, farmers can access their crops like never before for higher-quality tending and growing.

trailertail: fuel-saving aerodynamics technology

mon, 16 jul 2012 14:05:53 +0000

trailertail® acts to reduce the aerodynamic drag on tractor-trailers by streamlining the air flow behind the trailer, improving the truck’s fuel economy by about 6%.

this additional 6% fuel efficiency can be achieved in 30 minutes with a 2-person installation crew. when combined with other fuel efficiency technologies currently available, trucks can gain upwards of 25% more fuel efficiency, improving the miles per gallon of a tractor-trailer to over 10 mpg for the most efficient fleets in the country.

if the 2 million trailers currently operating in the us today were equipped with trailertails, america’s fuel consumption would be reduced by 5.6 billion gallons over the next decade, saving trucking companies over $20 billion in fuel costs. this aerodynamic add-on would help to keep consumer prices down and prevent 77,000 tons of carbon dioxide from being released into the atmosphere.

improving fuel efficiency of agricultural engines in india

fri, 25 mar 2011 14:39:00 +0000

step-less transmission systems that can be incorporated into existing tractors and harvesters, eliminating the need for gears and gear boxes in the power train. a simple arrangement of two variable diameter pulleys connected by one angular contact vari-speed elastomer belt can be attached to the drive shaft, the pulleys being actuated by stepper motors and/or clutch-based hydraulic control systems.

this changeover could result in major savings in fuel by running the engine at its efficient speed and driving at any desired speed through stepless variations. also, major savings in weight can result from this implementation. this idea and its accompanying prototype developed in sri venkateswara college of engineering (www.svce.ac.in) was awarded as young innovator by villgro foundations (www.villgro.org) and iit madras (www.iit.ac.in). it was also sponsored for an exhibition at open minds 2011, organized by nciia (http://nciia.org/openminds/2011)

a revolutionary engine

mon, 21 mar 2011 10:29:46 +0000

india is primarily an agricultural country, and modern technology plays a major role in its agricultural practices. its farming machines are powered by internal combustion engines, with speed and torque variations effected using conventional gears, which causes the engines to lose fuel efficiency over time. to increase engine efficiency and to achieve infinitely variable transmission, our team is developing a pulley type continuously variable transmission
