This study investigated the status of mechanized power and self-propelled rice cultivation machinery in Guilan Province in northern Iran. The raw data was obtained from 2013 statistics of the Agricultural Jihad Organization of Guilan province. Power per unit of area, mechanization level, area per unit of self-propelled machinery, and mechanization requirement were calculated for eastern, wester...

Farm tractors in cultivation consume a big amount of fossil fuels and emit greenhouse gases to the atmosphere. Improving traction performance power transfer indices wheeled field terrain soil with higher (pull ability) at optimal travel reduction (TR) can optimize energy utilization. This study compares performance, fuel consumption, productivity, farm tractor equipped new drive wheel “rigid lu...

Right now employment of polices and tools to decrease the carbon emission through electricity generation from renewable resources is one of the most important problem in energy policy. Tradable Green Certificate (TGC) is an economics mechanism to support green power generation. Any country has the challenge to choose an appropriate policy and mechanism for design and implementation of TGC. The ...

overall energy efficiency (oee) is an important indicator of energy consumption in tillage operations. tillage energy was studied objectivity to accurately measure the oee of mf399-4wd tractor. the tractor was equipped with different types of sensors to measure and calibrate the required data including: fuel consumption, actual forward speed, wheel speed and slippage, engine speed, draft and dr...
