To enhance drivability while providing more precise speed control, John Deere has announced that it is bringing Electric Variable Transmission (EVT) to the largest models of its 8 Series Tractors. This will be available on all 410-horsepower models of the 8 Series lineup, including the 8R, 8RT, and 8RX models.
"An EVT has electric motors in place of the hydrostatic motors that improve transmission performance, reliability, and increased efficiency," said Ryan Jardon, marketing manager for John Deere. "The EVT brings everything customers appreciate from an Infinitely Variable Transmission (IVT) into higher horsepower 8 Series Tractors. Inherently, the electrical components of an EVT are extremely reliable, offer tremendous longevity, and provide better overall tractor control, along with a system built for easy serviceability and diagnostics. In addition, customers will notice an EVT operates more quietly than an IVT."
The EVT is designed to offboard electricity from the tractor to streamline additional power to reduce wheel slip and improve uphill performance. The tractors can also pull wide implements without having to use an extra ballast for support.
The largest models in the 9 Series lineup will now be powered by the new JD14X 13.6-liter diesel engine for model year 2023. This includes the John Deere 9R 640 and 9RX 640 Tractors. Model year 2022 390- to 590-horsepower 9 Series Tractors also feature this engine, which is designed to consume less fuel than previous editions.
"These new engines were built for outstanding performance, greater reliability, and we have made them easier to access and service," Jardon continued. "The engine features a 500-hour oil change interval, hydraulic fan drive, and a high-pressure common rail fuel delivery system for increased fuel atomization, efficiency, and power, along with faster start times. Customers told us they appreciate the lugging capabilities the new engine has brought to their 9 Series Tractors."
