Next generation AXION 900 delivers even more
Published on 05 September 2017
NEW generation CLAAS AXION 900 advanced technology tractors feature even more powerful engines, an optimised CMATIC continuously variable transmission and for the first time, a choice of two operating systems.
Released in 2011, the series has established a keen following among grain producers and contractors for its perfectly-matched engine and transmission, high fuel efficiency and exceptional ease of operation.
CLAAS Harvest Centre Group Product Manager – CLAAS Tractors, Dave Knowles, says the new series has undergone systematic refinement to further improve performance and convenience.
The four models, rated with a maximum output of 325 to 445 hp, share the proven and highly and sophisticated six-cylinder, 8.7 litre FPT Cursor 9 engine.
The Tier 4 engine includes a new variable geometry turbo that delivers optimum charge-air pressure according to the load and engine speed. “All models are capable of transferring their full power from a standing start and at all forward speeds without a boost,” Dave says. “In fact, 70 per cent of maximum torque is available even when idling. “The advanced low-speed concept means the engine develops 18 per cent more torque than previously at a lower speed. This reduces fuel consumption in all field and transport applications.”
Further fuel savings are achieved by automatically reducing the idling speed from 800 to 650 rpm when stationary.
In the ECO mode, up to 95 per cent of the maximum engine output is transferred to the PTO shaft despite the reduced engine speed, allowing heavy implements to be operated at a lower engine speed.
All models are equipped with an upgraded ZF Terramatic transmission to match the higher output of these tractors. “This continuously variable transmission features outstanding power transmission and efficiency in all speed ranges from 50 m/h to 50 km/h,” Dave says. “Its new software further refines engine-transmission coordination and incorporates customer requirements under real-world conditions. “For example, the cruise control can be deactivated using the accelerator pedal and the driver can switch between two saved engine droop values simply by pressing a button.”
All models can be specified with the new CLAAS Information System Plus (CIS+) or proven CLAAS Electronic on-Board Information System (CEBIS). The former features a 178 mm (7 inch) CIS colour display mounted on the A-pillar and the proven multi-function armrest incorporating the ELECTROPILOT four-way control lever and DRIVESTICK control lever. “The new CIS+ is an intermediate system that is aimed at customers who want greater convenience and efficiency but do not need all the functionality of the CEBIS system,” Dave says. “It offers customers the option of using the CMATIC continuously variable transmission without the CEBIS system.”
The updated CEBIS operating system features a new 300 mm (12 inch) touch-screen display and an ergonomic armrest incorporating the CMOTION multi-function control lever. “This system provides convenient operation of all the main functions using just the thumb and two fingers,” Dave says. “The new software and intuitive operation offers many new functions for rapid and straightforward operation. “For example, frequently-used tractor functions can be accessed simply by tapping the machine silhouette on the CEBIS touch display.”
Factory-fitted GPS steering and CLAAS TELEMATICS remote monitoring systems are available in all models and configurations.
All AXION 900 tractors have load-sensing hydraulics with an output of 150 or 220 L/min and release levers for all hydraulic couplings at the rear. “The function buttons on the armrest and multi-function control lever can be configured for any of the spool valves,” Dave says. “This reduces the driver’s workload, especially during combined operations, as there is less need to change hand position.”
In the CEBIS version, the driver can assign priority to any of the eight spool valves. “The pre-set oil volume for the prioritised spool valve then remains almost constant even when other spool valves are in use,” Dave says. “This prioritisation option is useful when operating equipment, such as hydraulic motors or pneumatic precision seed drills, that require a constant oil flow. An opening and closing ramp for each spool valve can also be defined in the new CEBIS terminal. This means the driver can specify how quickly a spool valve should deliver the maximum pre-set oil flow after activation, allowing hydraulic motors or smaller hydraulic rams to be operated more gently with less wear.”
All AXION 900 models are fitted with a universal (ISO500) tow hitch support and a six-way adjustable drawbar.
A pick-up hitch is also available.
Other practical options include up to 20 LED working and road lights, wide-angle mirrors with two separately adjustable fields of view, a compressed air connection mounted near the left-hand steps and a removable tool drawer with telescopic runners. “The drawer is big enough to hold a conventional standard toolbox, allowing the on-board tool kit to be changed to suit different types of work,” Dave says. “Another useful detail for practical day-to-day use is the easily accessible, external battery terminals on all models. This means that the tractor can be used as a power source for other jobs, such as in-field refuelling.”
Next generation CLAAS AXION 900 tractors will be available to order in New Zealand and Australia from early 2018.
