John Deere has announced updates to its new 9R Series tractor range, now headed by the 691hp (maximum power) flagship 9R 640 and 9RX 640 models.
The manufacturer says the latest 9R, 9RT and 9RX machines are stronger and more efficient than their predecessors and also more intelligent, with increased operation and management simplicity thanks to connectivity and automation features.
All the tractors use the new 13.6-litre John Deere engine, as seen in the firm’s the X9 combines, with the exception of the top 640hp (rated power) models which are still powered by a 15-litre Cummins engine. The new flagship models have a 22hp increase at maximum power over the previous flagship, the 9620RX.
Its own six-cylinder engine has been developed to operate more efficiently, with noise levels reduced by up to 50 per cent, the manufacturer claims. In order to transfer power to the ground, all models offer additional ballasting options that allow a gross weight of 30.4 tonnes.
Like its 8R tractors launched previously, the StarFire 6000 receiver is integrated into the cab roof and is included as standard, along with the 4600 CommandCenter display, full IsoBus compatibility and AutoTrac activation.
To unlock the full suite of automated features, the manufacturer offers a full activation package costing £1,425. This includes turn automation, section control, variable rate control, passive implement guidance, in-field data sharing, machine sync and now also the firm’s new AutoPath row guidance.
In addition, the new AutoSetup feature allows farmers and contractors to pre-schedule jobs in the customer’s personalised Operations Center. Jobs appear automatically on the cab display when the machine enters the field and the operator only has to confirm with a single button click. The system supports settings such as client, farm, field, field boundaries, tracks, implement widths/offsets, products, application rates, site specific applications, documentation settings and operator name.
Once the job is completed, all data can be transferred wirelessly to the Operations Center. The manufacturer suggests AutoSetup can save up to 90 per cent of setting up time in the field and provides clear documentation to avoid errors and data losses.
The cab that features on the recently redeveloped 7R and 8R tractors now features on all 9R models, in addition to individually developed suspension systems for the 9R, 9RT and 9RX.
Inside the cab, the second generation ActiveSeat is available with leather trim, heating, active air circulation, massage function and various adjustable seat settings. A 6.5 inch DAB touchscreen radio with 6.1 sound system provides modern infotainment and is compatible with Apple CarPlay, while LED lighting is included.
Thanks to the reduced size of the exhaust after treatment system and optional cameras, visibility on all sides has been further improved, according to the manufacturer.
The manufacturer adds that the e18 transmission, axles, track drives and chassis have been significantly reinforced for higher capacity and longevity.
