DEUTZ-FAHR has added three new 4-cylinder models to its existing 6 series 6-cylinder range. The modular high tech system now includes a 6155.4, 6165.4 and 6175.4 as a top model.
All models in the range now feature higher permissible weights (11,500kg) and a longer wheelbase (2,543mm) for improved stability and a comfortable driving performance. Design features of the 4-cylinder models are similar to those of the 6-cylinder versions which were awarded “Tractor of the year for the design” last year.
The 156hp, 164hp and 171hp Deutz TCD 4.1 4-cylinder engines comply with the requirements for emissions Stage IV. The new engines offer a hefty starting torque and high torque reserves across a wide speed range. In addition to a compact cooling system, which can be opened completely and easily cleaned, the TTV models are also equipped with a new electric Visco fan.
Three transmission variants are available: from the simple, manual five-speed powershift transmission with six forward powershift stages and three reverse stages (30+15 gears) and the newly developed fully automatic RCshift gearbox (30+15 gears, with creeper gear 54+27 gears), to the efficient TTV transmission for continuous driving and working from 0 to 50km/h. For all transmissions, the maximum speed is achieved at a reduced engine speed to save fuel. On the RCshift models, the top speed of 50km/h is reached with only 1,530 rpm, saving fuel and reducing noise.
Another unique feature of this tractor class is the front axle with independent suspension, which is equipped with an anti-dive and anti-rise control and a booster brake system. This ensures maximum traction and safety in all situations.
The hydraulic system has also been adopted from the 6-cylinder models and can be configured individually depending on the operation requirements. The standard pump capacity is 84litre/min on the basic models, and an LS system with a capacity of 120litre/min as standard on the higher spec models, with options of 160 or 170litre/min. Up to five electro-hydraulic auxiliary control valves can be selected at the rear, and two at the front. All electronic valves can be proportionally controlled.
The position-controlled front linkage (4,110kg lifting capacity) is a new option for the TTV models. The 3-point hitch can be equipped with up to 4 hydraulic outlets and an ISOBUS interface at the front. The rear linkage can lift up to 9,700kg. Four PTO speeds at the rear (540, 540ECO, 1000, 1000ECO) come as standard, as well as an optional 1000 or 1000ECO at the front.
The 4-cylinder models come with a MaxiVision cab and the new InfoCentrePro, a new armrest and improvements to all-round view and operating convenience. 4th Gen LED lights are available as an option to enhance the visibility during night work. All models can be equipped with Agrosky and are thus ready for precision farming.
