Expanding its current six-cylinder 6 Series tractor range, Deutz-Fahr has added three new four-cylinder models.
While the manufacturer previously had a four-cylinder offering in the 6 Series, these new additions are more powerful and feature a heavily revised design. All three overlap with equivalent six-cylinder models providing customers with a shorter and lighter alternative tractor.
Four-cylinder models are identified by a 4 at the end of their model number; 6155.4 (156hp), 6165.4 (164hp) and the 6175.4 (171hp). All three feature higher permissible weights (11,500kg) and a longer wheelbase (2,543mm) for improved stability and a comfort, says the manufacturer.
As ever, power comes from Deutz TCD 4.1 4-cylinder engines which comply with Stage 4 emissions legislation.
Three transmission variants are available; a manual five-speed powershift transmission with six forward powershift stages and three reverse stages giving 30 by 15 gears, the newly developed automatic RCshift gearbox with 30 by 15 gears or 54 by 27 with creeper gear, and the continuously variable TTV transmission.
For all transmissions, maximum speed is achieved at reduced engine speed to save fuel – RCshift models can achieve this at 1,530rpm, says the manufacturer.
Up-front the tractors’ suspension features a self-levelling function which prevents nose dive and raise when the tractor is accelerated or decelerated.
The hydraulic system has also been adopted from the six-cylinder models. Standard pump capacity is 84 litre/min on the basic models, and a load sensing system with a capacity of 120 litre/min as standard on the higher spec models, with options of 160 or 170 litre/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.
Position-controlled front linkage (4,110kg lifting capacity) is a new option for the TTV models. The front linkage can be equipped with up to four hydraulic outlets and an IsoBus interface at the front.
Rear linkage can lift up to 9,700kg. Four pto speeds at the rear (540, 540ECO, 1,000, 1,000ECO) come as standard, as well as an optional 1,000 or 1,000ECO at the front.
Sharing the new family styling as, four-cylinder models come with the firm’s MaxiVision cab, the new InfoCentrePro and a new armrest layout. All models can also be equipped with Deutz-Fahr’s Agrosky precision farming suit of tools.
The new tractors are available now and expect more four-cylinder 6 Series models to be revealed at Agritechnica in November.
