An unidentified manufacturer, possibly Russian, is expected to unveil a 295 horse power diesel-electric tractor which can generate 170kW for powering sprayers or fertiliser spreaders.
John Deere’s E Premium tractors were first in the industry to provide power for external use.
They are designed for improved engine efficiency and a fuel consumption reduction of as much as 5%. The required level of electrical power is directly produced by engine flywheel mounted generators, and is subsequently converted to meet the specifications of the relevant components, implements or external tools.
The generator supplies electrical power to the cooling fan, air conditioning compressor and air compressor, as well as a 12V/300A electrical system with up to 5kW power at either 230V or 400V to operate tools or other external electrical devices. John Deere claims acceleration during road transport and PTO work in the field is significantly improved. This new feature extends the use of these tractors beyond typical farming applications, to industrial, municipal and road construction use, because of the electrical power generation at low engine speeds. The 7430E and 7530E Premium tractors have 12V at 300A continuously available on board.
