John Deere combine harvesters get 2026 overhaul with productivity boosts
John Deere has announced new automation and efficiency updates on its 2026 model combine harvesters that provide more capabilities and boost productivity by up to 20%.
Owners of this large prime mover will be able to choose wheeled (9R), twin track (9RT) or now the new four track, centre pivot version (9RX). There are four models, powered by the latest Tier 4 engines -- the smallest 470hp, the largest a mighty 620hp.
The smaller 470 and 520hp units make use of a 13.5L John Deere Powertech engine, the larger 570 and 620hp models use a 15L Cummins QSX plant. Both offer high torque and constant power throughout the rev range.
Transmission is via the e18-full powershift transmission with 'Efficiency Manager'. This automatically matches engine load and target speed to shift to the correct speed in the transmission for best performance and fuel economy.
From the transmission, drive power is transferred to large diameter drive sprockets and large heavy duty drive lugs to Camso Duradrive 3500 or 6500 belts which transmit the power to the ground.
The 30 or 36 inch wide belts are supported by optimally spaced idlers and mid-rollers which ensure great grip and minimal slippage.
Up on top, the operator sits in the Commandview cabin supported by a new four-link mechanical cab suspension giving up to 10cm of movement – much more comfortable.
To help the driver get the best performance out of the machine, there is well known JD technology such as Auto Trak for guidance, JD Link for connectivity, and a new Active Command Steering system (ACS) for easier headland turns and line holding ability at road speeds.
A new hydraulic system can support up to eight selective control valves with 235L/min flow; this can be beefed up to 435L/min for high demand applications.
"The new 9RX brings to the market John Deere's 20 years of experience gained with the 8RT and 9Rt tractors," says John Deere product manager for the 9 series, Jerry Griffith.
He also notes that customers say the new tractor is easier to manoeuvre and has power to get the job done.
