Deutz-Fahr has launched two new high-power models with continuously variable transmissions and new engines capable of producing up to 260hp. Introduced at Agritechnica 2011, the 7 Series models meet the latest Stage IIIB emissions standards.
The new tractors have been named according to the new designation format introduced by the company to coincide with the new engine technology. The 7230 Agrotron TTV has a maximum power output of 240hp, while the 7250 Agrotron TTV offers up to 263hp.
With a maximum torque of over 1,000Nm, the new tracors feature the Deutz TCD four-valve/clinder turbocharged 6.1-litre Stage IIIB engines that offer plenty of power for even the most demanding tasks. The engines are equipped for AdBlue exhaust treatment affording a significant reduction in harmful emissions.
In the more powerful engine, the pressure in the AdBlue injection system has been increased from the previous level of 1,600 bar to 2,000 bar. This makes for considerable improvements in power delivery and fuel consumption and, when combined with the new turbochargers, leads to optimal engine response and efficiency.
The innovative features of the models are not limited to the new engines but also extend to the Deutz-Fahr TTV transmission. The improved response of the engine has led to optimisation of the transmission for maximum driveability. The transmission recognises and responds to changes in load and traction and ensures greater safety when, for example, towing trailers on the road.
The new models are equipped with the new PowerCom V control management system, which has been significantly redesigned. A feature completely new to Deutz-Fahr is the ability, where legal, to reach a potential top speed of 60km/hr, which means that 50km/hr can be attained at an engine speed of just 1,650rpm.
The new models also feature a high-spec PTO with three speeds (540E/1,000/1,000E), electrohydraulic control, load detection and proportional startup to help protect the attached implement. With a choice of two economy speeds, much PTO work can be carried out at lower engine speed.
Further improvements to the driveline include the possibility to fit extendible half-shafts for track width adjustment or to allow the fitting of twin wheels.
The models are equipped with a load-sensing hydraulic system capable of delivering an oil flow rate of 160 lit/min. The hydraulic system has its own, separate oil tank.
Up to seven electrically controlled spools – five at the rear and two at the front – are available for efficient control of complex implements, including front and rear implement combinations. All spool valves are equipped with timers and flow control.
All the models are equipped with the new Class S2 cab. The new multifunction armrest groups together all the tractor controls in one place, leaving free the side consoles, which now benefit from a new and more ergonomic design.
Ergonomics are further enhanced by the new iMonitor with its larger display and touch-screen controls. The new cab also features a new lighting control panel with intuitive, time-saving controls for a quicker response when working.
In addition to the new side console design and the new iMonitor, operator comfort has also been addressed by fitting the latest-generation seat for the driver along with a comfortable passenger seat.
The cab structure has been improved with a one-piece windscreen for better forward visibility and reduced noise inside the cab. Last but not least, there is the automatic climate control system with front air outlet vents that, being integrated in the steering column, are adjusted along with the steering wheel and thus are always positioned correctly relative to the operator.
The Powerbrake braking system on the 7 Series now represents the benchmark for operator comfort and braking capacity; the Electronic Parking Brake (EPB) with intelligent braking function regulates the braking force to suit the load in conjunction with the active control of the TTV transmission.
