Following its Agritechnica preview last November, John Deere has revealed further details on its new flagship X9 combine, the manufacturer’s largest to date.
Featuring a cleaning area some 36 per cent larger than its previous range-topping combine, the S790, the manufacturer reckons 100 tonnes per hour through put is achievable.
Initially two models will be launched, the X9 1000 and the X9 1100.
Separation and cleaning area on both machines is identical, with a twin rotor design responsible for threshing.
A 1,750mm wide channel feeds the X Series Dual Separator (XDS) which are 3.51 metres long with a diameter of 601mm. Crop is subjected to nine revolutions of the XDS, the manufacturer says, while rotor speed can be altered between 300 and 1,300rpm. Concave area is 1.6sq.m with a total separation area of 22.5sq.m.
Cleaning is taken care of by the manufacturer’s Dyna-Flo XL cleaning shoe, which boasts a total louvered area of 6.97sq.m.
The smaller model boasts a grain tank of 14,800 litres with an unloading system capable of 159l per second while the larger model has a 16,200l tank and an unloading rate of 186l/sec. There is the option for an unloading auger up to 9.45m in length.
Both use the manufacturer’s new 13.6-litre PowerTech PWS engine, with rated power at 549 and 603hp respectively. Maximum power outputs are 639 and 700hp.
The 1,250l fuel tank can be fully refuelled in under 2.5 minutes with the firm’s new FastFuel System, providing filling speeds of up to 550 litres/min, enough for 14 hours of work, according to the company.
A new double pump hydrostatic transmission has also been added. The manufacturer says the ProDrive XL offers 30 per cent more torque than the existing ProDrive for hillsides and wet conditions as well as 40kph road speed with engine speed management to 1,700rpm. Upon starting both pumps are activated, for maximum torque. As speed increases the second pump fades out of action, reducing fuel consumption, according to the company.
The X9 also features a new cab offering more storage space, more USB ports and better connectivity. Operator comfort has been enhanced with a seat which swivels 16 degrees right or left, and has heating, ventilation and massage functions. There are three different cab specification levels, Select, Premium and Ultimate, all with LED lighting as standard.
The company says thanks to developments in transmissions, crop handling, cleaning systems and its new Xcel straw chopper knives, harvesting power requirements have been reduced by 120hp.
It has also announced a raft of new headers with working widths up to 15.2m.
Hinged Draper Extended Table (HDX) drapers are fitted with patented grain-saver draper belts, which together with the fingered top augers are said to reduce oilseed rape cutterbar and pod shatter loss by up to 25 per cent. HDX drapers are available in cutting widths from 10.7 to 13.7m.
In addition, the manufacturer has also launched the Hinged Draper Rigid Knife (HDR) model. This is aimed at farmers growing little or no oilseed rape and is available in sizes from 10.7 to 15.2m.The company will start taking orders for the new combine later this summer, with new machines expected be on farm for harvest in 2021.
