Clean power.

The Vithar K90 range is equipped with a 3.8 litre-4-cylinder 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.

Transmission.

OS-Frame

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.

Synchro gearbox

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 700 meters per hour 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,
better operating quality.

Reversibility.

Available as an option, the reversible driving position makes it possible to work professionally with the attachment positioned in front.

It takes just a few seconds to turn the operator’s module (seat, steering wheel and dashboard) by 180° so as to work with extreme precision, quickly, comfortably and safely.

Everything under control.

The driver’s seat of Vithar K90 is set-up to-measure for the driver with all of the controls set up ergonomically and easy to use.

Cushioned seat and height-adjustable steering wheel (standard) ensure maximum operational comfort.

The new automotive dashboard houses, in addition to the electro-hydraulic controls, a colour multi-functional display to constantly monitor each machine parameter.

Functional design.

The Vithar K90 range features an aggressive design yet functional, characterised by muscular and elegant lines.

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