“…A number of instrumentation systems based on data logger and computers have been developed to measure the performance of tractors and implements. These systems vary in complexity and sophistication from measuring one or two parameters and recording display readings by hand (Williford, 1981) to on-board microcomputer-based monitoring of several operating parameters (Wolf et al, 1980;Adsit and Clark, 1981;Wendte and Rozeboom, 1981;Tompkins and Wilhelm, 1982;GrevisJames et al, 1983;Clark and Adsit, 1985;Thomson and Shinners, 1989;McLaughlin et al, 1993;Al-Janobi et al, 1998;Sahu and raheman, 2008;Al-Hamed et al, 2010;AlSuhaibani et al, 2010;Younis et al, 2010). A review on different instrumentation systems shows that the majority of these systems were designed for an exclusive tractor and not easily adoptable to others, they are not portable.…”

A mobile instrumentation system was developed and mounted on an MF 285 tractor to measure the performance parameters of the tractor and attached implements. The system measures implement draft, fuel consumption, real forward velocity, tillage depth and engine speed. Other parameters such as wheel slippage, drawbar power and traction efficiency would be calculated by ASABE standard. Overall energy efficiency for the tractor-implement system was calculated, too. Three implements included of moldboard plow, disk plow and chisel plow at four forward velocities (1.5, 2.3, 3 and 4 km/h) in 23 cm depth and 1500 rpm engine speed was examined. Analysis of variance (ANOVA) of resulted data revealed that increase of forward velocity results in increase of implement draft, wheel slippage, drawbar power and overall energy efficiency but results in decrease of traction efficiency. Furthermore, fuel consumption decreased by increase of velocity from 1.5 km/h to 3 km/h but increased by increase of velocity from 3 km/h to 4 km/h. Moreover, it was observed that draft requirement for implements in tests ranged from 8.2 kN for the disk plow to 13 kN for the chisel plow and fuel consumption ranged from 10.72 L/ha for the chisel plow to 26.5 L/ha for the moldboard plow. The ranges in mentioned parameters indicate that energy saving can be readily done by selecting energy-efficient implements and by proper matching of the tractor size and operating parameters to the implements. ª 2015 The Authors.

“…Energy management of agricultural machinery will also be increasingly important in the future. Draft requirements will also be required for energy management decisions [18]. The implement draft force is used to determine the fuel consumed for soil tillage because the decrease in draft could lead to a decrease in tractor's fuel consumption.…”

Estimating the amount of fuel consumption of an agricultural tractor during various tillage operations will help the selection of the best conservation practices for farm equipment. Draft requirements often dictate the size of the power unit required on a particular farm and, therefore, will also be required for energy management decisions. They will also be considered a prominent factor during the selection of a tractor’s machinery and power source. In addition, ground speed measurement is not only necessary for many agricultural machinery applications but also to monitor and map crop yield and properly change the application rate of agricultural inputs. There are several methods and techniques to measure a tractor’s fuel consumption, draft force, and ground speed. All these methods have many advantages and disadvantages depending on the tractor, the implement used, and the operating conditions. This article reviews some of these methods, providing scope for further research to focus on the potential development and improvement of the measurement methods, and this could positively affect the accuracy of the data and final results of the research.

“…Kirisci et al (1993) divided drawbar dynamometers into two groups, frame type and linkage type. A frame type dynamometer consists of transducers mounted on a specially constructed frame which is inserted between the tractor and the implement (Kitson, 1987;Thomson and Shinners, 1989). A linkage type dynamometer has the force transducers built in the hitch links themselves.…”
