RS | Steering wheels

The oversized rear wheels, available in 20 or 24”, ensure high lifting capacity (2700 kg) and traction on any type of ground.

The OS-Frame and the steering acting on the front wheels ensure stability and adherence in any operating condition, even on slopes.

The standard manoeuvring brakes further reduce the turning radius for more agility between the rows.

Clean power.

Fighter K90 is equipped with a 3.8 litre-4-cylinder Turbo Kubota engine which develops 75 hp and a vigorous torque of 305.4 Nm @1500 rpm.

The latest-generation Common Rail engine ensures:

precise injection control,
more efficient combustion,
improved performance,
less fuel consumption.

The engine revs are electronically adjusted quickly by a manual lever and a button that stores and retrieves the set speed.

Transmission.

Engine and clutch are connected by a single transmission shaft which moves both the gearbox and the PTO, ensuring compact dimensions and greater steering angles.

A joint placed in the central part of the tractor allows the fore-carriage to oscillate up to 15° with respect to the rear carriage, stabilising the set-up on slopes or uneven ground, constantly ensuring maximum drive of all four wheels.

The synchronised gearbox consists of 4 ranges and 4 speeds for a total of 16 gears both in forward motion and in reverse, with synchronised reverser.

The logical speed sequence (from 0,7 to 40 km/h) makes it possible to always select the right gear for the intended use, allowing:

fuel savings
less stress on the mechanical components
a better operating quality.

The hydraulically controlled multidisc in oil bath clutch is much softer and more efficient than traditional dry clutches, always ensuring precise control of the tractor by the operator.

Using this type of advanced hydraulic clutch, inserted inside the transmission, results in a series of concrete advantages:

longer life
no maintenance
maximum manoeuvrability thanks to the more compact dimensions of the tractor.

New workstation.

The driver’s seat was designed to combine ergonomics and comfort with close attention to the layout of the controls according to the logic applied to field tractors.

The new workstation features all the directional control valves and lift operating levers positioned on the right side, (also in the version with controlled draft), and the right bumper now has an electro-hydraulic control for PTO engagement.

Accordingly, all the controls for hydraulics can be easily used by the operator with his/her right hand, while the left hand stays firmly on the steering wheel.

Also, from the seat the operator has a complete and unobstructed view of the rear tool as well as the machine and wheel track.

Maximum protection!

‘Compact Pro’ cab | Fighter range

Ultra-low profile and Cat. 4 approved

The low chassis with height off the ground of only 170 cm makes use under the foliage, in pergola vineyards, canopy plantations and greenhouses extremely easy.

Pressurised and homologated in Category 4, isolates the operator from harmful inhalations during treatments with phytosanitary agents, making the work environment healthy and safe.

Functional design.

Fighter K90 features an aggressive design yet elegant and functional, characterised by a muscular line which nevertheless provides the driver optimal visibility.

In addition to the four optical units on the front bumpers, two LED headlights above the bonnet grille increase the lit area to facilitate work at night or in poorly lit environments.

Additional options.

Front bumper

Robust steel accessory that combines style and functionality by protecting the bonnet and radiator grille from impact.

Front ballasts

Ballast weighing a total of 150 kg, designed for mounting on both sides of the bonnet so as not to increase the size of the tractor.
