First seen at Agritechnica 2007, where they were awarded a DLG Gold Medal, John Deere’s new 7430E and 7530E Premium tractors will be fully available in the UK and Ireland in late spring 2009. Rated at 165 and 180hp (97/68/EC), rising to 200 and 215hp with Intelligent Power Management (IPM), these tractors are equipped with an integrated, high-power electricity generation and distribution system.
A generator fitted between the engine and transmission provides the power for electrically driven components such as the air-conditioning compressor, engine-cooling fan and air-brake compressor, resulting in increased engine performance and better fuel efficiency. In addition, these tractors can provide external electrical power of up to 5kW through two power sockets, rated at 230 and 400V.
This design is the first example of electrical power being utilised to improve overall tractor efficiency, with the E power management system controlling the various component drives at the appropriate time. The precise engine cooling fan speed is infinitely regulated by the system according to engine temperature, which leads to higher power levels at lower engine speeds for improved fuel economy.
The air brake compressor is able to fill the air reservoir quickly only when required, even at low idle. In hot conditions, the electrically driven air conditioning compressor also runs independently of engine speed, leading to increased comfort for the operator.
Moreover, thanks to this innovative system, the 7430E and 7530E Premium tractors have 12V at 300A continuously available on board. In addition, the power sockets allow the operation of most handheld and fixed tools commonly used in both agricultural and industrial applications.
Other key customer benefits of these 7030E Premium Series tractors include an additional 10hp from the engine’s Intelligent Power Management (IPM) system, which leads to better acceleration on the road and an improved load response during PTO work. This also means more comfortable operation as well as easier servicing and maintenance.
