The Deutz-Fahr Agro XXL: a green giant!

The Agro XXL is a conceptual prototype designed in collaboration with Deutz-Fahr and the DTU (Deutsche Traktoren Union).
Tractors of this size are increasingly common in Eastern European countries.

Indeed, thanks to their enormous fields, which allow work over very large widths, the limiting factor is very often tractive power. Same Deutz-Fahr decided to present this concept at Agritechnica to gather the opinions of a broad, international audience.

This 600 ch tractor did not leave people indifferent!

With the Agro XXL's drive concept, Deutz-Fahr is taking a new path because, for giant tractors, the problem is not engine power but the transmission of that power to the ground.

The AgroXXL has already undergone numerous tests, but many practical trials remain to be carried out before it can be marketed.

Maneuverability and soil protection thanks to the 8 wheels

The Deutz-Fahr Agro XXL relies on four driven axles and an articulated chassis. The two pairs of articulated axles are driven by cardan shafts. The rear pair of axles can be engaged or disengaged electrically. This saves fuel on the road and reduces wear. Both pairs of axles are equipped with differential locks that can be engaged under load.

Thanks to this axle arrangement, depending on the tires, ground contact areas are obtained that are greater than or equal to those of crawler tractors. At the same time, thanks to the articulation with an angle of 40°, a small turning radius of 5,50 m (inside) or 8,75 m (outside) is achieved.

With its running gear, the AgroXXL giant tractor offers full road compatibility with a maximum width of less than 2,85 m.

The gross vehicle weight is 32 t. The braking system features hydraulically assisted, oil-cooled brakes on both pairs of axles.

An engine with a displacement of 16 liters

The Agro XXL is powered by a DEUTZ V8 turbodiesel engine of type TCD 2015 V08 with intercooler, which delivers a maximum power of 600 ch and has a displacement of 16,0 l. Low noise emissions, a high torque of 2800 Nm from 1300-1500 rpm, low fuel consumption and long oil change intervals contribute greatly to reducing operating costs.

Shifting under load

The Full Powershift transmission has 18 forward and 6 reverse speeds. Its maximum speed of 40 km/h is reached at reduced engine speed.

In the main working range of 5 to 13 km/h, 10 speeds are available, shifting smoothly and without jerks. For good acceleration, it features a Kick Shift function that allows gears to be skipped. The transmission is also equipped with an electric parking brake.

Load-sensing hydraulic circuit

The hydraulic system of the Deutz-Fahr AgroXXL is of the load-sensing type and comes as standard with four electro-hydraulic valves, with six available as an option. The flow rate is 170 l/min with an operating pressure of 200 bar.

Various hitch combinations and options are available. They match the implements requiring this tractive power.

A spacious cab

The cab of the Deutz-Fahr AgroXXL is spacious and very comfortable. It is equipped with the PowerCom control lever, an iMonitor and an ergonomic layout of switches and controls.

A passenger seat, air conditioning and various storage options are also standard equipment, as well as a mini-fridge.

After all, drivers can spend up to eight or ten hours in the cab, which is not a problem with a fuel tank with a capacity of up to 1 200 l.

In addition, Deutz-Fahr also offers the necessary auto-guidance technology to relieve the driver even further with its satellite-assisted "Agrosky" system. Depending on the system used, accuracy of up to +/2 cm is achieved.
