Deutz-Fahr has introduced three new additions to its Agrotron TTV range – the Agrotron TTV410, Agrotron TTV420 and Agrotron TTV430 – doubling the number of models on offer to six with power outputs from 120-260hp.
This power range means there is now a TTV model to suit all classes of farming whether it is the need for powerful, high-torque, fuel-efficient tractors on large arable farms or for the lighter and smaller machines required by livestock farmers. In all situations the continuously variable transmission is there to enable operators to select the optimum and most economical speed for the task being performed.
The new Agrotron tractors are powered by the latest electronically managed four-cylinder Deutz-turbo-diesel Series 2010 engines that feature common-rail fuel injection, four-valves/cylinder and external exhaust gas recirculation. The maximum power outputs are 121hp (TTV410), 130hp (TTV420) and 142hp (TTV430).
Available with either 40 or 50km/hr TTV transmissions, maximum speed is reached at an engine speed of just 1,800rpm (50km/h version) or 1,600rpm (40km/hr). The engines are also approved for biodiesel (B100) use.
The TTV transmission fitted to the new Agrotron TTV400 models features a high mechanical efficiency – up to 100 per cent of the driving power is mechanically transmitted, reducing the higher energy absorbing hydrostatic ratio to a minimum.
There are three drive and work modes to support the transmission’s different operating ranges. In addition to the automatic mode, in which nearly 75 per cent of all tasks can be carried out, there is a special operating mode for PTO-operations that automatically switches on when the PTO shaft is activated. There is also a manual mode.
Speed is varied steplessly within each working range by a hydrostatic unit. This gives the operator the possibility of infinitely variable travel speeds from 0-50km/hr – or by simple programming, 40km/hr – using the combination of the planetary trains and the hydrostatic unit.
The Agrotron TTV 410/420/430 tractors have an active stop control enabling the tractor to be braked without using the service brake and held in a stopped position.
The rear PTO offers four standard speeds : 540, 540E, 1 000 and 1,000E. Activation of the PTO can be from the cab and also from push buttons on the left-hand rear mudguard – this electro-hydraulic control ensures a modulated, low-stress PTO start-up.
In auto-mode the PTO automatically switches off during lifting and is reactivated when the rear linkage is lowered, helping to ensure linkage-mounted implements are protected against damage.
With the economy PTO engaged, fuel consumption, engine load, noise, driver stress and the environmental burden are all reduced considerably due to the low engine speeds employed. An optional integrated front lift with front PTO (1,000rpm) is also available.
The S-Class cab of the Agrotron TTV400 models is fitted with more than 6.5 square metres of glass to provide good allround visibility that is further enhanced by a roof window. Access to the cab is safe and easy with the S-Class boasting one of the widest opening doors on the market today.
On board furniture includes the PowerCom V armrest control used for all the main operating controls while other controls are grouped and colour coded together for ease of identification according to their function, that is hydraulics, auxiliary valves, PTO and transmission.
Conveniently positioned, simple to operate and easily understood: the new iMonitor from Deutz-Fahr not only makes it easier to operate the tractor, but also offers a range of new functions. The iMonitor is operated from a multi-controller that enables the driver to activate the individual tractor menus and allow them to be programmed accordingly.
With an integrated Bluetooth hands-free kit, MP3 player, integrated radio and a reversing camera, the iMonitor brings a new mode of operation to tractors. It can also be used for Isobus-controlled devices.
The new Agrotron TTV400 tractors have a pressure and volume-controlled hydraulic load-sensing system with a pump flow capacity of up to 110 lit/min and a system pressure of 200 bar. A closed-centre system uses an axial piston, variable-displacement pump controlled by hydraulic demand. On implements with multiple hydraulic requirements, the system having the highest pressure requirement determines the oil pressure.
The tractors can be equipped with up to seven double-acting remote valves, each with four functions. All remote valves can be locked in either the lift or float position and also used as single- or double-acting. Each valve has a separate oil flow control and, as a result, each individual hydraulic component receives the oil volume it requires. To avoid confusion, control levers are colour-coded and specifically assigned to the hydraulic connections. All remote connections at the rear of the tractor can be coupled under pressure and are equipped with rapid break-away couplings and an oil collecting pan.
Large lifting cylinders provide a rear linkage lift force of 6,200kg and implement coupling and uncoupling can be achieved through use of the external lift buttons on the rear mudguard.
Fuel economy is one of most important issues and, in the new tractors, Deutz-Fahr engineers have incorporated a range of hi-tech features that have resulted in one of the most economical tractor concepts in the industry. For example, the engine is equipped with an electronic viscous fan that ensures the temperature of the cooling water remains within the optimum range and that the engine does not overheat.
The new Power Brakes are 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 have made the distance between the discs fractionally wider. Tests have shown that at maximum speed (50km/hr) the brake disc tolerance improvements have reduced power absorption by up to 8hp – extra power available for use by the tractor.
The load-sensing hydraulic system is also improved. By fitting a separate hitch oil reservoir, the amount of oil needed within the transmission section can be reduced and this means less power is absorbed during operation, particularly when travelling at higher speeds. A separate hydraulic reservoir reduces the risk of dirty oil coming from the implements and contaminating key transmission components.
The prices for the TTV410, 420 and 430 models are £76,071, £78,449 and £80,796 respectively.
