New engine and transmission for Deere tractors
Select larger horsepowered tractors to receive new JD14 engine and Electric Variable TransmissionJohn Deere has announced it is offering a completely redesigned new engine on its 9 series tractors and the award winning Electric Variable Transmission on its largest 8 series tractors for MY23.
The new JD14 engine produces 640-rated horsepower and will be offered on 9R 640 and 9RX 640 tractors. Internal testing of these machines has shown the new engine uses seven per cent less fuel than previous models, the company said.
John Deere Australia/New Zealand Production System Manager, Ben Kelly, said the new engines were built for outstanding performance, exceptional reliability and ease of access and service.
"The 9 Series Tractors are among John Deere’s most popular machines and often play an integral role within our customers’ businesses,” he said.
“It is critical the engine at the tractor’s heart is as efficient and reliable as possible, and the all new JD14 has been developed to deliver the power and performance needed to maximise operations.
“Key features include a 500-hour oil change interval, hydraulic fan drive, and a high-pressure common rail fuel delivery system for increased fuel optimisation, efficiency and power, in addition to faster start times.”

Recognised with a gold medal at Agritechnica 2019, John Deere’s Electric Variable Transmission (EVT) will now be available for all 410hp machines including 8R, 8RT and 8RX models, to deliver stepless transmissions for infinite speed control and drivability.
The EVT has electric motors in place of the hydrostatic motors that John Deere said serve to improve transmission performance, reliability, and increased efficiency.
Kelly said the EVT would deliver a range of benefits to the performance and efficiency of the 8 Series, and would likely be the transmission of choice moving forward.
“This includes greater reliability and longevity, as well as better overall tractor control, in addition to a system built for easy serviceability and diagnostics,” Kelly said.
“Customers will also notice the EVT operates more quietly than an IVT, for greater operator comfort.”
Additionally, producers can choose to add electric power generation capable of offboarding electricity to power implements on 8 Series Tractors equipped with EVT.
John Deere claimed the EVT is the industry’s only transmission that enables electric power generation (up to 100kW) that allows farmers to power implement fan drives, take the place of implement hydraulic pumps, or assist the tractor by powering the implement’s axles.
"EVT technology can also contribute to reducing wheel slip, improving up-hill performance and enabling the tractor to pull wide implements without the need for extra ballast or a larger tractor, and does this by offboarding electricity to deliver additional power to the implement,” Kelly said.
The new upgrades are available to order now on MY23 8 and 9 Series Tractors. For more information about the John Deere’s 8 and 9 Series Tractors, visit johndeere.com.au
