Hanover, November 13th, 2011; At Agritechnica, Lamborghini Tractors introduces three new models to its R6 VRT continuous variable transmission range. The new models, the R6 VRT 115, R6 VRT 125 and R6 VRT 135 will expand the R6 VRT range to include models from 120 hp up to 222hp.
The new tractors are aimed at farmers and agricultural contractors requiring powerful, economical and high-torque tractors which are suitable for a wide variety of work in arable and grassland situations.
From the very beginning of this project, power efficiency has been one of the key objectives. In this popular power category, tractors are used extensively for spraying and fertiliser application on large arable farms and, on livestock farms, for loader work along with a multitude of other tasks. Although the span of work these tractors can achieve is amazingly wide, all farmers share a common need: they want a powerful, flexible, comfortable and economic tractor.
Equipped with the latest fuel efficient 4-cylinder Deutz-Turbo-Diesel engines from the Series 2012, the new R6 VRT 115/125/135 tractors benefit from use of the DEUTZ common rail fuel injection system (DCR), DPC and four-valve technology as well as external exhaust gas recirculation (EGR) for a maximum power output of 121hp, 130hp and 142hp (89, 95 and 116 kW).
The use of four valves per cylinder improves the gas flow into and out of the engine and means that fuel and air is mixed effectively to make the combustion process more effective. These electronically controlled intercooled engines provide a comfortable driving and working experience together with low fuel consumption – the result of the engine’s, high torque and reserves of power over a wide rpm band. They provide both reliability and smooth power delivery. Equipped with modern high-pressure injection systems that achieve injection pressures of up to 1,800 bar, the engines provide efficient fuel utilization, tremendous efficiency and first-rate emission numbers.
In both versions – the 40 and the 50 km/h – the maximum speed is reached at a reduce engine speed of 1.800 rpm (50 km/h version) or 1.600 rpm (40 km/h). And with a 220 litre fuel tank they can work long hours without the need to refuel. Of course, the engines are approved for bio-diesel (B100).

Setting standards in operators comfort
Equipped with the well-known VRT transmission the new tractors offer simple and driver-friendly operation and a four-fold power-take-off (540/540E100/1000E). The ergonomically formed multicontroller, which combines all of the important functions of the tractor, is also on board. The benefits are obvious: drivers can save time, ensure safety and achieve a quick reaction time when working because they will be able to operate the lever intuitively after just a short period of time.
As in its bigger brothers, the VRT transmission of the new R6 VRT models boasts a high mechanical efficiency and three operating ranges. In each of these three operating ranges, up to 100% of the driving power is mechanically transmitted, reducing the hydrostatic ratio to a minimum.
As a result, the vehicle can be operated without hydraulic losses even in low speed ranges. This high degree of efficiency is due to the direct power flow from the engine to the planetary transmission, shuttle transmission, PTO and axle. Operating speed is continuously variable within each working range and gives the driver the possibility of infinitely variable travel speeds from 0- 50 km/h (or by easy programming, 40 km/h).
The transmission has three drive and work modes over the different operating ranges. In addition to the automatic mode, in which nearly 75% of all tasks and transportation journeys can be carried out, there is a special operating mode for PTO-operations, which automatically switches on when the power take-off shaft is activated and a manual mode.
Furthermore, the R6 VRT 115/125/135 models have an active stop control which allows the tractor to be braked to a halt without using the service brake and then start off again using the accelerator, without activation of the clutch. Also new is the hydraulic parking brake, which, similar to cars, provides easy operation and high safety.
Four PTO speeds as standard
The rear PTO has four standard speeds (540/540E/1.000/1.000E), a feature which increases the versatility of the tractor. The bolted on PTO shaft can also be fitted with a number of different profiles. Activation of the PTO can be from both from the cab and by using pushbuttons on the left-hand rear mudguard and electro-hydraulic control ensures modulated, low-wear PTO start-up. In auto-mode the PTO automatically switches off during lifting and is reactivated when the powerlift is lowered. Operating errors are avoided and mounted implements are protected against damage.
Standard-feature economy PTO
With the economy PTO, fuel consumption, engine load, noise, driver stress and the environmental burden are all reduced considerably as the result of low engine speeds. The speed of the economy PTO is within the lowest fuel consumption range yet – due to the engine power curve – still at a very high performance and torque level. You still get a lot of power, even in economy PTO. An optional integrated front lift with front PTO (1,000 rpm) is also available.
Comfortable working space
The S-Class cab of the R6 VRT is a market leader in terms of visibility. With over 6.5m2 of glass area the S-Class cab offers unsurpassed visibility to all areas around the machine. A roof window is a popular addition, especially if the machine is fitted with a front-loader. Access to the cab is safe and easy with the S-Class boasting one of the widest opening doors on the market today. All main operating controls are grouped in the right hand armrest and colour coded together for ease of identification according to their function, i.e. hydraulics, auxiliary valves, PTO and transmission.
iMonitor as optional equipment
Clearly arranged, easy to operate and understand, the new iMonitor from Lamborghini Tractors not only makes it easier to operate the tractor, but also offers an impressive range of new functions. The iMonitor is operated from a multi-controller which enables the driver to move individual tractor menus into position for setting and operation by pressing and turning. This operating system is similar to that now used as standard by manufacturers of premium class cars for the operation of navigation systems and similar menu-prompted components.
The attractive graphic displays in the black display screen are clear and logical in design, with the use of familiar and logical symbols,the driver will recognise.. For greater comfort the driver can operate the controls with his arm on the armrest. With an integrated Bluetooth hands-free kit, MP3 player, integrated radio and an automatic reversing camera, it brings operating systems to tractors for the first time which are familiar and service-proven in cars. The iMonitor can also be used for ISOBUScontrolled devices enabling their control to be achieved using a single monitor.
Load-Sensing as standard
With the R6 VRT 115/125/135 you get a pressure and volume-controlled hydraulic system (Load- Sensing) with a pump flow capacity of up to 110 l/min and a system pressure of 200 bar. The closed centre system uses an axial piston, variable displacement pump controlled by hydraulic demand. The system pressure drops as oil flow is called for; only then does the variable displacement pump automatically provide more oil so that the pressure demanded is maintained. The component r with the highest pressure requirements determines the current system pressure.
The R6 VRT 115/125/135 can be equipped with up to seven electro-hydraulic double-acting remote valves, each with four functions. All remote valves can be locked in either the lifting or floating position and also used as single or double acting. Each valve has a separate oil flow control. As a result each consumer receives the exact oil volume it requires. The control levers are colour-coded and specifically assigned to the hydraulic connections.. All remote connections at the rear are coupled under pressure and are equipped with rapid break-away couplings and an oil collecting pan. With the easy-reach cross-gate lever you have total command of two remote valves. You can, for example, raise the front loader and operate the push-off fork at the same time. Rear linkage lift capacity is6.2 tons and implement coupling and uncoupling can be achieved using the external lift buttons on the rear mudguard.
Fuel saving features
A key fuel saving feature for the new tractors is the eVISCO Fan (Electronic viscous fan), which is electronically controlled and ensures that the temperature of the cooling water remains within the optimum range and that the engine does not overheat. If no cooling air is required, the Visco clutch switches off and runs at a lower speed. If the requirement increases, a special silicon oil flows from the reservoir into the workspace. There, with the help of fluid friction, the drive torque is transferred to the fan without wear. If the valve closes, the silicon oil runs back, friction decreases, and the fan once again rotates freely.
A new design of new Power Brakes is also able to save fuel. In addition to the introduction of a brake booster to reduce pedal braking effort, internal changes to the brake disc tolerances made distance between the discs fractionally wider. The result: Tests have shown that at maximum speed (50kph) the brake disc tolerance improvements have reduced power absorption by up to 6kW.
The LoadSensing hydraulic system has also been improved and saves fuel as a result.. By fitting a separate hitch oil reservoir, the amount of oil needed within the transmission section can be reduced. A reduced transmission oil level means less power is absorbed during operation, particularly when travelling at higher speeds. A separate hydraulic reservoir also reduces the risk of “dirty” oil coming from the implements contaminating key transmission components.
