7R Power & Efficiency
Engine and Transmission Options
With engine horsepower up to 246 kW (330 hp), the 7R Series Tractors, powered by the John Deere PowerTech™ PSS 6.8L or PowerTech™ PSS 9.0L engine, outperform both in the field and during transport. They do it all, while delivering outstanding fluid economy.
Engine Options
John Deere PowerTech 9.0L Engine
The 7R 290, 7R 310, and 7R 330 Tractors are built with the John Deere PowerTech PSS 9.0L Engine. The field-proven variable geometry dual-turbocharger actuates the turbo vanes as required to provide more consistent engine boost pressure and the ability to respond to load quickly across the engine rpm range. The benefits: Increased low rpm torque, quicker response to load, increased peak torque, improved fuel economy, and improved performance at high altitudes.
John Deere PowerTech 6.8L Engine
The 7R 210, 7R 230, 7R 250, and 7R 270 Tractors feature the John Deere PowerTech PSS 6.8L Engine. This engine utilizes two turbochargers – a variable geometry turbocharger (VGT) and a fixed geometry turbocharger, providing the torque rise and engine response needed to meet varying load conditions. The benefits: Increased low rpm torque, quicker response to load, increased peak torque, improved fuel economy, and improved performance at high altitudes.
Emissions Control
Our integrated Emissions Control system consists of a cooled EGR, a diesel oxidation catalyst (DOC), diesel particulate filter (DPF), and a selective catalytic reduction (SCR) system — all specifically designed to meet the rigorous demands of agricultural applications. This seamlessly integrated solution can use less diesel fuel and DEF for total fluid economy. The aftertreatment system is streamlined into a smaller package than on previous models, which improves visibility from the cab and uses less DEF.
Cooling System
The cooling system delivers even in harsh operating conditions. It limits dirt and debris buildup, operates at a reduced noise level compared to previous models, and offers easy serviceability.
Transmission Options
e23™ PowerShift Transmission
The e23™ PowerShift Transmission option with Effciency Manager™ pairs the benefits of a mechanical transmission with the ease of an Infinitely Variable Transmission (IVT™). The transmission has 23 forward gears evenly spaced 15% apart to provide a wide speed range to complement different operating conditions and implements. The spacing also provides smooth shift quality which helps improve ride quality and helps maintain maximum ground speed at reduced engine rpms to save fuel. The e23 also provides 11 reverse selections with a 30% speed change between gears.
Infinitely Variable Transmission (IVT™)
The IVT gives you the best in performance and operation. The IVT operates similarly to the traditional gear-up and throttle-back operation performed manually with other transmissions. Dial in a specific ground speed and the transmission and engine work together to keep the tractor there, instantly responding to changing load conditions.
New CommandPRO™ Control with an IVT
Experience seamless control of your tractor and implements all in the palm of your hand. Move from parked to top speeds with a simple push of a button. Eleven customisable buttons let you match functions to the job, with options to configure various set speeds to keep you in command.
