Deutz-Fahr - Model 60 Series - Combine Harvesters
From Combine Harvesters
The remarkable new 60 Series is the product of DEUTZ-FAHR's many years of experience in harvesting and its ongoing commitment to developing new technologies, innovative processes and state of the art machinery. The 6060/6060HTS/6065HTS five straw walker models and 6090/6090HTS/6095HTS six straw walker models set new benchmarks for performance for the combined harvester segment. Unparalleled harvesting performance with superior cleanliness of the finished product and grain protection combined with low running costs and facilitated maintenance.
The high performance cutter bars (measuring from 4.20 to 7.20 m in width) have a monolithic structure for superior stability, durability, weight distribution and reliability. The large diameter feeder auger with broad spirals and helically distributed auger fingers ensures continuous feed and product transfer. The auger fingers are quick and easy to replace, and are mounted on a safety pin which retains the fingers themselves in the event of breakage.
Schumacher cutting system
The Tandem cutting system has an alternating surface for clean and a blade with individually bolted sections and an excursion of 105 mm. This ensures clean, quiet operation and minimised wear and, above all, a precise cutting action.
The blade carrier tines are extremely sturdy and closely spaced to prevent the risk of foreign objects passing through and damaging the blades.
One of the greatest strengths of the Schumacher system is its planetary gear transmission: this extraordinary solution allows very high cutting rates and maintains a perfectly straight blade alignment for superior mechanical efficiency, optimised power transmission and low maintenance costs.
This is an electronic cutter bar control system, which keeps the cutter bar uniformly aligned in all terrain and crop conditions.
This system also automatically damps cutter bar oscillations during transport to prevent the risk of damage to the mechanical components of the combine harvester.
The AutoControl function also corrects the transverse position of the cutter bar relative to the ground up to an inclination of 14% on the base version and or 20% on the Balance version. The working principle is very simple: specific sensors mounted on large metal feelers monitor the status of the bar, and transmit the relative parameters to an electronic control unit, which adjusts the bar position accordingly, independently of combine harvester inclination.
Proportional pick-up reel
The pick-up reel is equipped with six bars, each carrying a set of extremely resilient and flexible plastic teeth, which are settable at an adjustable angle and individually replaceable far easier maintenance.
The pick-up reel is mounted on arms sliding on Teflon guides (for quick, precise hydraulic adjustment of tooth inclination), and is also easily adjustable in position horizontally or vertically relative to the cab, to cater ideally for different crops and harvesting conditions.
The pick-up reel may be synchronised with ground speed. Once the driver initially sets the ground and pick-up reel speeds, when the ground speed is subsequently increased or decreased, the pick-up reel speed is automatically adjusted to maintain the same proportion between the parameters.
Two special kits for installation on the cutter bars (up to 6.3 metres in width) are available for harvesting sunflower seeds and rapeseed.
This first kit consists of special extensions used simultaneously together with a smooth cylinder (installed in front of the feeder auger) and a toothed roller (mounted under the cutter bar instead of the pick-up reel, which is removed) to harvest the crop efficiently and quickly.
The kit for rapeseed differs from the sunflower seed kit as it also includes an extension for the table and a vertical cutter blade on the right hand side of the hydraulic transmission (or with a blade on the left hand side, as an option).
The feeder channel has alternating rasp bars fastened to three chains; the carrier shafts are fitted with toothed guides to prevent slippage between chain links, to ensure continuous feed to the machine and prevent channel overload.
The front shaft is adjustable to optimise threshing results with wheat or maize, while the intermediate shaft improves feed to the threshing drum and clears accumulated crop from the channel.
Feeder channel inversion
Drive is via a two-groove V-belt (an optional three-groove V-belt is available for use with maize pickers) for efficient power transmission with minimised noise.
The electric inversion system plays an extremely important role, as it allows the direction of the feeder channel and bar may be inverted electrically to prevent the risk of feed system overload.
Cutting angle adjustment
The cutting angle is adjusted mechanically with tie-rods. An electrohydraulic cutting angle system is available as an option, which optimises cutter bar position for the direction of travel, and adjusts the cutter bar position in response to uphill or downhill gradients to maximise productivity.
60 Series combine harvesters are equipped with a state of the art threshing system which ensures extraordinary levels of crop quality. This is robust, highly productive and reliable threshing system, which handles the crop delicately during grain separation.
The threshing drum is available in two widths, both with the same diameter of 600 cm. 6060/6060HTS/6065HTS models are equipped with a 1.27 m wide threshing drum with five straw walkers, while 6090/6090HTS/6095HTS models feature a 1.52 m wide drum with six straw walkers. Both variants are equipped with eight rasp bars (screw-mounted for quick and easy replacement) for a perfect threshing action.
Crop enters the threshing drum horizontally for uniform, blockage-free feed, while an access aperture above the feeder channel facilitates maintenance.
The multi-segment concave (4 mm wire diameter) has been specifically designed to allow immediate reconfiguration of the combine harvester when needed for different crops: the standard segments are simply removed the segments from the stone guard cavity of the concave and replaced with specific segments for the crop.
The concave also has fifteen rasp bars arranged with a pitch of 121 degrees, for superlative threshing and separation efficiency.
The input and output distances between the concave and the threshing drum at the front and rear are independently adjustable by electric motors controlled by the Commander Control system.
Thresher drum reduction gear
The threshing drum is equipped with an efficient variable speed transmission making is possible to set the ideal speed for each crop. The speed may be set and electronically maintained within a range from 420 to 1,250 rpm, while an automatic variable speed transmission tensioner system protects belts and threshing drum against overloading.
For particularly delicate crops, and additional reduction gear unit is also available to reduce the operating speed range of the threshing drum to a very low 210 - 625 rpm.
60 Series HTS models are equipped with a 590 mm diameter turbo separator with ten toothed rasp bars, which increases productivity by up to 20%. The system uses centrifugal force and additional mesh (with a spacing of 40 mm), which adds 0.81 m² of surface area to the combine harvester, to ensure extremely effective grain separation, even in the most challenging conditions.
The turbo-separator may be set electrically into five different positions (for a drum excursion from 25 to 65 mm) and operate at two speeds: 775 rpm for crops with smaller seeds and 410 rpm for crops with heavier seeds.
The straw walkers have a very large surface area, are particularly long and have an extended excursion ensure that every last grain is separated from the straw, while the first step of the straw walkers is deeper that the others, to slow the flow of crop exiting the threshing system and improve the efficiency of the first stage of separation.
The straw walkers are mounted on special, hermetically sealed, maintenance-free bearings, which reduce noise and power loss and increase the lifespan of the shaft and of the straw walkers themselves.
And for even greater separation efficiency, the straw walkers may be fitted with specific crests, while the return pan is specifically shaped so that the crop already reaches the grain pan in stratified form.
The turbine works in conjunction with the double step system to clean enormous quantities of crop; while the crop is fed back to the grain pan for maximum grain protection without overloading the threshing system.
The very long grain pan moves with a reciprocating motion to ensure perfect stratification of the chaff and straw. As these two components are lighter than the grain, they are blow away immediately upon contact with the air flow produced by the ventilator, for more effective cleaning of the finished product. The grain pan is easily removable from the combine harvester, minimising maintenance times and simplifying the operations needed to reconfigure the machine for a different crop.
Sieves and ventilation system
The sieves are mechanically operated and adjusted with levers, and are easily removable and fitted with tall separator blades.
A system for electric sieve adjustment from the Commander Control is available as an option.
Using dual sensors and a control bar extending along the entire width of the threshing tank, the sieve control system monitors the productivity of the combine harvester precisely.
The high performance (400 mm diameter) turbine with 24 vanes aspirates air along the entire width of the combine harvester. The transverse air flow volume is controlled by deflectors which advance or retard air delivery to the sieve for uniform delivery over the entire length of the tank.
The recovery system ideally redistributes material that has already be treated over the grain pan: a solution that prevents threshing system overload and the risk of grain breakage or increased straw walker grain loss.
The DGR uses friction inserts (with interchangeable types for different crops) to exert an additional threshing action on the recovered grain.
The recovery rate is monitored continuously and an alarm signal warns of overload conditions.
Grain tank capacities offered by the 60 Series are: 7,500 litres for 6060 models, 8,500 litres for 6060HTS and 6065HTS models and Balance variants, and 9,500 litres for 6090, 6090HTS and 6095HTS models. Rapid emptying minimises time wastage, while powerful motors discharge the tank effectively while working, for no loss in productivity.
The level in the tank is observable via a window in the cab, while the threshing quality may be checked via an external grain sampling hatch.
Two sensors in the tank activate an indicator light and an audible warning signal to inform the driver that the tank is full, and that it is necessary to bring the tractor near the thresher for discharging onto the trailer.
A discharging capacity of 90 l/min ensures that the tank is emptied rapidly, while discharge speed is adjustable with specific deflectors in the tank near the discharge auger.
The 4.3 metre high discharge outlet means that the tank may be emptied even when moving, and allows product to be transferred easily even into large trailers. Measuring 5.6 metres in length and with a generous 110 degrees of mobility, the discharge pipe means that the combine harvester can work with a large range of cutting widths, and ensures that the operator has a clear view of the discharge outlet at all times.
The aperture and closer of the discharge pipe is be controlled easily from the cab via the Commander Control.
The integrated straw chopper is equipped with a rotor with 48 cutter blades arranged in four rows: This configuration produces an air flow which spreads material uniformly over the entire surface of the cutter bars, and may be adjusted with manually controlled deflectors (electrical adjustment system available as an option).
The position of the counter-blade is adjustable to obtain the degree of chopping required, while the system may be set to thresh even very heavy crops by simply changing two pulleys, without requiring additional reduction gears.
Like the straw chopper, the chaff spreader is designed to distribute material over even the broadest cutter bars, for perfect mixing of the chopped material.
The transfer pan (which transfers the product to be processed) ensures uniform chaff distribution, while a conveyor with metal chutes directs the chaff to the four-blade rotors.
The angle of the chaff spreader is adjustable to ensure ideal distribution with different crops, while blades on the rotors include specific deflectors which regulate air flow for superlative distribution results without very high power demands.
The engine of a combine harvester must be capable of powering additional or optional accessories, and must have a sufficient torque reserve to maintain maximum productivity even in the most challenging conditions, with no loss in threshing component speed.
Modern 4 valve per cylinder DEUTZ Common Rail engines offer the perfect solution for this specific application, and combine outstanding power with extraordinary efficiency, for superior threshing performance with optimum fuel efficiency and productivity.
These TCD 6.1 and TCD 7.8 6-cylinder engines (with the former equipping 6060 and 6060HTS models, and the latter used in 6065HTS, 6090, 6090 HTS and 6095 models) cover a power range from 250 to 365 hp.
Putting every ounce of power to work
Power is taken off from both ends of the crankshaft, making it possible to separate hydraulic and mechanical functions, and ensuring a direct transmission system with no power losses.
This also means that fewer drive belts are used, and that the belts themselves are more accessible, reducing the running costs for the combine harvester.
DCR SCR engine
What sets the DCR (Deutz Common Rail) system apart from other solutions is that it uses two injection pumps (with flow regulation to limit diesel recirculation) embedded in the cylinder block and lubricated with engine oil. This solution is safer and more reliable than a conventional system, as the lubrication of the pumps is not dependent on fuel flow.
SCR is an exhaust after-treatment system which reduces nitrogen oxide emissions in the exhaust gas by selective catalytic reduction with AdBlue® additive.
The four-speed hydrostatic transmission lets the driver maintain the ideal speed for all harvesting conditions, and adjust the speed continuously from a level next to the driver seat. The ideally spaced ratios ensure that there is always plenty of torque on tap to tackle even the most critical traction conditions.
The gears of the reduction unit and gearbox are lapped to reduce operating noise without compromising the durability and reliability of the transmission system.
Load sensing hydraulic system
The hydraulic system equipping 60 Series machines delivers the ideal flow of hydraulic oil to power all the main control functions while also ensuring superlative precision and smoothness.
The pumps are built for superior durability and reliability, and are suitably sized to cater for any power demand.
The Load Sensing system optimises power delivery and consumption. The hydraulic pump is controlled in relation to load, so that oil is delivered at the exact pressure and in the precise quantities necessary for the effective demand.
The “Commander Cab IV” cab offers an extraordinarily comfortable working environment, and is mounted on four silent-blocks to minimise vibration and noise (with an internal noise level of just 74 dBa).
Extraordinary visibility: the 180°C curved windows in athermic glass offer a panoramic view of all corners and the cutter bar.
Completing the extraordinary levels of equipment offered by the cab are an air-sprung seat, a three-way adjustable steering column, a powerful air conditioning system with four filters and pre-installed wiring for an audio system and a CB radio.
The CCM (Combine Control Management) module lets the driver monitor all the productivity parameters of the combine harvester: total and partial processed terrain area count, hourly production, losses, recovery level in relation to grain size and cutter bar position. The module also continuously monitors vital machine parameters such as total threshing hours and partial and total hours of engine operation.
The CCM module uses a membrane keypad with 14 backlit buttons.
For maximum productivity, these machines are equipped with a set of six or eight work lights (depending on version), and with two rear work lights, a spotlight on the grain tank, a spotlight on the discharge pipe and two rotating beacons indicating when the tank is full.
As an option, two of the standard lamps on the cab roof may be replaced with xenon lights to increase the illuminated area.
The standard lights may be complemented with the “Visibility Pack”, which adds the following elements: two lights for illuminating the rear of the bar, two lights on the handrails and four lights illuminating the entire maintenance area.
This kit consists of three cameras for supervising the area around the combine harvester, with one camera mounted on the rear for supervising the area behind the machine (which is particularly useful for manoeuvring), another on the left hand side (offering a view of the tank discharge zone) and a third camera at the bottom rear of the combine harvester, offering an ideal view of the tow hook, straw chopper and chaff spreader.
