The most mechanized agricultural operations include a tractor as a primary power unit, even though the tractor itself is not particularly useful without an implement attached. Innovations and efficiency improvements in tractor engines, powertrains, and auxiliary power systems have been ongoing since tractors were invented a century ago and significant gains have been realized. However, PTO and hydraulic power systems are well established and effective for today‟s applications, the search for more versatile and efficient power transfer continues. One alternative is electric power, which first debuted in 1954 on the Farmall Electrall tractor (Michael, 2012). The recent research suggests electric drives would be suitable and beneficial for almost all the drives on modern agricultural machines, which currently use hydraulic and mechanical power. Electric drive enables variable speeds control; therefore, functions can be operated independently of engine speed and use only the power and energy needed for the given function. ISOBUS, a communication protocol for high voltage power electronics controller networks on agricultural machinery, is a key enabler for advanced controls that take advantage of torque and speed control capabilities of these electric systems. Electric powertrain promises the higher fuel efficiency and better torque-speed control over the mechanical and hydraulic one. Hence, it is inescapable to switch over to electric powertrain so as to meet the forthcoming requirements of sustainable precision agriculture and to reduce the global emission.
