Combines and tractors at French show

The first of new mid-sized combines and high-horsepower tractors from Deutz-Fahr

The first showing of new mid-sized combines and the launch of new high-horsepower tractors from Deutz-Fahr took place at the French Innov-Agri show in early September. David Williams attended the event.CombinesReplacing current 6065 and 6090 models, and fitting in to the Deutz-Fahr combine range between the 6060 and 6060HTS, and C9000 machines, the new C7205 and C7206 combines from Deutz-Fahr have many of the latest features introduced on the larger C9000 range last year.Available for the 2015 harvest the C7000 range incudes four models; two with five straw-walkers and two with six, both available in higher specification TS versions and also hill-side versions in TSB model designations.TS models have more power and a Turbo Separator which is a third drum designed to allow high separation performance even in difficult, wet or weed-infested working conditions.The system is adjustable in five stages allowing the operator to match the aggressiveness of the system to the characteristics of the crop being handled, which also means straw can be protected from excessive threshing and damage, for baling.They also have more powerful engines, the improved threshing performance and power providing up to 20 per cent more output than the standard system.The five-walker C7205 and C7205 TS are powered by Deutz 6.1-litre 6-cylinder engines, the C7205 with 250 and 287hp for the TS version. The C7206 has six straw-walkers and a Deutz 7.8-litre 287hp 6-cylinder power unit and the TS variant has 334hp. The engines all use SCR (Adblue) to meet Tier 4 interim exhaust emissions standards.Separation and cleaning is achieved with a 600mm threshing drum, 1.27m wide on 7205 models and 1.52m on the larger machines. An optional segmented concave allows the operator to replace sections with different spacings between the rows to suit specific crop types for precisely matched threshing performance, and the front and rear of the concave are adjustable independently from the screen in the cab, for optimal flow. The sieves can be adjusted during work from the cab using an optional electric adjustment system, and a dual-flow grain return system allows the operator to select two different operating speeds for the returns to optimise the sample and throughput.A cross-flow cleaning fan moves air through upper and lower channels across the entire fan housing.Grain tank capacities are increased over previous models, to 8,500 litres for the 7205 and 9,500 for the 7206 machines. Unloading capacity is also increased to meet the extra throughput, to 90 litres per second.Selecting between chopping and windrowing straw is via a lever at the rear and a new option is electrically-adjustable deflectors which allow the operator to adjust the spread pattern from the cab.The combine chassis is completely new and strengthened to cope with larger headers and tougher working environments, and has allowed the choice of headers to be extended, a new 9m version now available for six-walker models.The Varicrop header, which offers an extendable table bed, is an option for UK machines in the C9000 and C7000 ranges, and provides an adjustable bed length from the standard 370mm to a maximum of 1,070mm. Working widths available in the Varicrop range are 5.5, 6.5 and 7.5m.Autocontrol is a standard feature on all headers, ensuring accurate contour following by maintaining an even ground pressure and there is also manual adjustment of the cutting angle provided, with hydraulic adjustment an option.As on its tractor ranges, Deutz-Fahr has taken the opportunity presented by the updating of its models to introduce significant styling changes, and the smart-looking bodywork and cab have been created jointly with Giugaro Design. The new side panels look smart, but also offer improved access for servicing, gull-wing doors folding up well out of the way to access the drive systems, but requiring minimal space at the sides when folded so access can be gained even when the machine is parked close to walls and hedges.The new Commander Cab V is significantly improved, with materials chosen for their comfort and ease of cleaning as well as their noise absorption properties.Access is easier thanks to new steps, which can pivot for access from the front or to the side making them practical for movement around the yard as well as for use in the field. The steering wheel is straight from the C9000 machines. A new fitment last year, it offers three directional adjustment so all operators should be able to find an ideal operating position. A fridge below the passenger seat is available as an option.Acknowledging the demand for machines to work longer into the night Deutz-Fahr has equipped the new C7000 combines with better work lights, and upgrades include extra side, under-cab and hand rail lights as well as Xenon work lights.Visibility is very good, and the new specification includes better rear view mirrors than before. Up to three cameras can also be fitted.All the new C7000-series models use the multi-function Commander Stick joystick for control of most operating functions and the Commander Control screen is used to set up and adjust the header, threshing system, concave and Turbo Separator as well as for grain tank discharge parameters.Rear axle options include 4wd and an anti-skid function. On the front axle, 716mm wide rubber tracks can be specified, homologated for road use up to 25kph, and keeping the overall width under 3.5m, making them a useful upgrade for those doing a lot of road work as well as providing extra grip and reduced compaction in the field.For hillside work the TSB models can compensate for lateral slopes up to 20 per cent and up or down-hill longitudinal gradients up to six per cent.”We are delighted with the new C7000 combines,” comments Same Deutz-Fahr UK product marketing manager, Graham Barnwell. “The new C9000 flagship has been well received and the new mid-sized C7000 models have superb features which will provide users with the high performance and productivity they require. We look forward to having them available next season and believe they will quickly prove popular with UK farms.”TractorsThe 9-series tractors from Deutz-Fahr were previewed at Agritechnica in 2013, but Innov-Agri was the first time they have been shown working in public, and marked their introduction to the French market with full production commencing this November.Offering power outputs from 274-336hp, they extend Deutz-Fahr’s horsepower offering past the current largest flagship, the 263hp 7250, and will provide the step up to the new flagship 11-series, due to become available late in 2015 with power outputs from 350hp.”Their arrival into the range opens up another market to us,” said Graham Barnwell, “Our dealers are delighted as the new tractors have a superb specification to suit larger UK farms and contractors, and their arrival also makes it easier for our dealers to extend the ranges of implement brands they offer to include those with the largest equipment.”The 9-series includes four models; 274, 295, 312 and 336hp, all with CVT transmission and all using the same Deutz power unit; a 7.8-litre, 6-cylinder engine with twin turbochargers, intercoolers, Deutz electronically-controlled common-rail fuel injection and SCR (Adblue) combined with a DPF (diesel particulate filter), to meet the latest Tier 4 final exhaust emissions standards. The twin-turbo design, using two different-sized turbos working in series helps provide excellent lugging power for a wide range of applications  – at low and mid speeds both turbos are used while at higher engine speeds only the larger second turbo provides the compression. This provides a very flat torque curve from just 900rpm at which 1,200Nm is generated.The CVT unit is made by ZF and provides a top speed of 60kph (where permitted), at an engine speed of just 1,780rpm, and 50kph at 1,480 rpm. Four mechanical ratios combine with the hydrostatic drive to provide flexibility and efficiency, controlled by the Deutz-Fahr intelligent electronic powertrain management system. The PTO offers three speeds; 540E, 1,000 and 1,000E, engaged electro-hydraulically and providing improved economy where situations allow. Front axle suspension is standard and 4-wheel anti-lock braking is an option.HydraulicsA 210 litre/min load-sensing pump operates at 200 bar to provide hydraulic oil flow for demanding implements through up to seven auxiliary spool valves with up to 150 litres/min available from up to four of them, and 100 litres/min from the others.

Rear lift capacity is a massive 12t, with 5t available at the front.

The all-new Maxi-Vision cab was designed by Giugaro and continues the smart modern appearance along the length of the tractor from the front radiator grill to the rear. The cab interior uses quality materials for reduced noise and comfort as well as ease of cleaning.An optional 12-inch touchscreen monitor, the iMonitor 2.0, is used to control the Agrosky GPS navigation, and ComforTip management systems. Data management and Tractor Implement Management (TIM), through which the tractor is controlled by the implements, is available through suitably-equipped implements including some from the current Krone and Grimme ranges.The show provided an opportunity for a first test-drive for Farmers Guide. The 9340 was operating in a confined area with a Lemken Karat cultivator, the space available allowing only a limited opportunity to test the performance. What was immediately noticeable was the ease of operation, the CVT transmission providing barely noticeable shifting through its mechanical ratios whether under load or when maneuvering on the headland. The finger-operated hydraulic lift and lower buttons were perfectly to hand and took no time to get used to. The range of adjustment provided by the seat and steering wheel meant there is plenty of room, even for a tall operator.The Giugaro-designed cab is very impressive, the layout clear and attractive, and the controls all just where one would expect them to be, and with a positive and natural feel. The engine is quiet, the maneuverability good for such a large tractor, the visibility all around is excellent and it took just minutes to feel at home in the cab.An issue with accessing the engines of larger tractors for maintenance is the height from the ground of the engine hoods, most using a spring lift to raise the bonnet when a latch is released, and a rope to pull it back down again when the work is complete. No such entry-level system on the Deutz, where a pair of buttons under the cab above the left hand steps allows the operator to electrically lift and lower the hood on a parallel linkage, the lack of a rear hinge meaning equal clearance is available at the front and rear with the bonnet raised.As with all high horsepower tractors transferring the power to the ground is a challenge, and requires the tyre pressures and ballast to be optimised for the working conditions. A built-in tyre inflation system is one of the options currently under development for the 9-series, and all other tractor models from the manufacturer.Planned production of the 9-series tractors is 500-1,000 per year and a spokesman confirmed that the new tractors will not be available in sister-company Same’s name and colours, being produced for sale only carrying the Deutz-Fahr brand name.
