Harvester improvements bring extra productivity

The launch of new C6000 series combine harvesters from Deutz-Fahr took place in early July

The European press launch of new C6000 series combine harvesters from Deutz-Fahr took place in early July in Croatia, close to the factory where they are produced. David Williams attended.

The event included a tour of the factory, a demonstration of the new combines harvesting barley and an opportunity to see all the latest tractors.
The C6000 models are available with headers up to 6.3m and are at the smaller end of the Deutz-Fahr combine range, below the C7000 and C9000 models. The two larger series were updated in 2013 and 2014, and many of their latest features have been carried forward to the C6000 machines, which will be available for the 2016 season.
The latest C6000 series combines from Deutz-Fahr will be available for the 2016 harvest.
C6000 models are designed to meet the needs of small to medium-sized farms and Deutz-Fahr combine product specialist for UK and Ireland, David Jefferson said he believes they will be well-received in the UK, particularly by traditional family farms wanting the latest technology from a modern, reliable machine with the ability to cope with a wider variety of crops even in difficult harvests.
The new C6000 range includes four models, all with the same Deutz-Fahr 6-cylinder 6.1-litre power unit meeting Tier 4 final emissions standards using SCR and Adblue, and producing 230hp (rated) and 250hp (max). Models availabe are the C629S and C6205TS – with an enhanced separation system, and there are Autocontrol versions of each, with contour following headers, also available providing four variations to choose from. A 3-speed hydrostatic transmission is standard providing up to 20kph.
The latest C6000 series combines are powered by Deutz-Fahr 250hp engines meeting Tier 4 final emissions requirements.

Comfort and productivity
For most operators, the biggest update is an all-new cab. The superb Commander Cab Evo 2 was launched for the larger C7000 and C9000 series machines and made the operator station of the C6000 seem quite outdated, but the mechanical controls have been replaced by electronic switch systems.
The most commonly used functions are all integrated on the Commander joystick, which has freed up the rear cab panel, to the left of the operator, for a proper passenger seat, below which an optional fridge can be accommodated.
The cab is significantly bigger than before and offers excellent visibility with a large curved front screen and narrow corner posts so that the operator has a near-perfect view of the header.
The C6000 has a brand new air conditioning system, this latest version surpassing that of the two bigger series. A new sun-shield will help operators working late into the evening when the sun is low and the seat is significantly more comfortable than that of the previous models, also helping prevent operator fatigue during long working days.
In recent years the company has invested heavily in design and aesthetics for its tractors and combines, and the cab of the C6000 is an excellent example of the resulting benefits. The cab looks functional but attractive and, from the operator seat, everything falls naturally to hand, with almost all the switches adjacent to the right armrest. The Commander Control Module (CCM), allows the operator to keep tabs on all aspects of the operation including productivity, cutting table position, and losses and re-threshing performance in relation to grain size. It also keeps track of hours worked and service requirements.
Unloading capacity is 75 litres/second and the new unloading auger design allows use in any position.
The grain tank is increased to 7,000 litres and the latest versions all have an upgraded unloading auger shifting 75 litres of grain per second, and capable of unloading in any position.
Four standard headers are available; 4.2, 4.8, 5.4 and 6.3m and all feature Deutz-Fahr’s planetary transmission drive providing up to 1,220 cutting strokes per minute. The Schumacher Easy cut 2 system, which has alternate standard and inverted cutting sections, is used. Optional Varicrop headers feature extending platforms and are available in 5.0, 5.5 and 6.5m widths.

Threshing and separation
Primary threshing is by an 8-bar 600mm main drum surrounded by a broad 121-degree concave. An optional speed reduction drive system is available, allowing speed to be halved for working in very light or sensitive crops, such as grass seed, saving fuel and minimising crop damage.
The de-awning plates are easily engaged or disengaged from outside the thresher housing.
The concave clearance is adjustable separately front and rear, using two levers conveniently located just outside the cab door. De-awning plates are adjustable from the outside too. A three-piece segmented concave is also available on which different spacings can be installed to adjust performance for different crops.
The segmented concave can be accessed and removed through the stonetrap and is a feature not available on previous C6000 models, having been introduced on the latest C7000 and C9000 machines. Behind the main drum is a separate 400mm beater drum, the speed of which is adjustable to provide a speed differential compared to the main drum. This allows the aggressiveness of its action to be adjusted to suit the crop and conditions.
On Turboseparator (TS) models, a third cylinder is installed after the second beater drum, but before the straw walkers. With 10 large-toothed feeder bars the cylinder can be adjusted in five stages to allow for more or less aggressive handling of the crop and is claimed to provide potential productivity increase up to 20 per cent, particularly in high-volume crops also affected by green matter or weeds. In easier conditions the unit can be adjusted for minimum effect, protecting the straw and saving fuel.
The C6205 models have five straw walkers, of long closed profile, said to ensure performance even in wet or weed-infested crops. A new ventilation system with a full-width cross-flow fan of 400mm diameter and with 44 blades along the length of its rotor blows air across the whole width of the separators.
Deutz-Fahr combine product specialist David Jefferson said of the new combines; “At SDF we realised that the market segment between 500 and 1,000 acres is very important. These customers need a reliable machine with outstanding performance to enable them to be both independent and efficient with their harvest. The features of the new C6000 range; the very latest in operator comfort, new ergonomic controls and increased productivity, are all very important but having this available at a competitive price is what customers need.”

Minimising losses through un-threshed grains is the DGR double return system. Unique to Deutz-Fahr, this uses a cross auger after the sieves to feed unthreshed heads to two impeller-type threshing units on either side. From the impeller, the heads are thrown back up through two channels and distributed across the width of the preparation pan which means the extra material is shared equally across the whole separation system. Spreading the returns across the entire sieve area means that when the combine encounters an area where returns are high; there isn’t the tendency for one area of the sieves to become overloaded as can occur with conventional returns systems. It also removes the need to direct returns back to the main drum which would reduce the harvester’s capacity.

Straw chopper
The straw chopper is an option and it has a simple, single lever manual engagement along with manual adjustment of spread width. A chaff spreader, which makes subsequent cultivations easier by spreading chaff over a wide area rather than in a dense row directly behind the straw walkers, is an option.

Maintenance
Fuel tank capacity is 450 litres and there is a 53-litre Adblue tank.
A logical drive layout helps make maintenance straight-forward with the main threshing system drives on the right hand side and the transmission drives taken from the left. A bank of grease points on each side mean lubrication points aren’t missed and are colour coded for greasing frequency.
Access to the engine is easy.

Manufacturing plant
The Deutz-Fahr combine manufacturing plant is at Zupanja, in eastern Croatia, in an area primarily devoted to agriculture. The plant opened in 1980, producing combines for the home market as well as for export to the east and it worked in cooperation with several manufacturers over the years before being acquired by Same Deutz-Fahr in 2005.
The factory at Zupanja, Croatia, produces more than 400 combines per year, most of which are sold within Europe. An impressive 70 per cent of components are manufactured and assembled at the plant.
The factory has a capacity of up to 1,000 combines per year, but currently produces approximately 400, and it employs 200 full-time workers, taking on an additional 200 part-time during the main production periods.
European sales account for approximately 84 per cent of production, with Germany the largest single market at 25 per cent and France taking 16 per cent.
Huge investment has been made in research and development of the machines in recent years, as well as in the production plant and currently 70 per cent of the combine’s components are manufactured on-site, including many of the transmissions which are assembled and tested in-house before being fitted to the machines.
Straw choppers are one of the main components bought in, as the company says it has an excellent relationship with the current supplier and would find it difficult to improve on the quality of manufacturer, so there is no current plan to change this sourcing arrangement. Other items bought in include engines, tyres and glass windows, but there is a strategy of continuously increasing the proportion of components produced in-house as this saves costs and increases the company’s independence.
