CABIN CAT. 4
The driving platform is hanging on silent-blocks
to dampen vibrations and noise to the advantage of operating comfort.
The new COMPACT PRO cab
, available on request, is characterised by a low-profile monocoque chassis
that optimises the work under the foliage, in pergola vineyards, canopy plantations and greenhouses.
Equipped with air conditioning with automotive-design air vents set up in front of the operator, the COMPACT PRO cabin is pressurised and homologated cat. 4
The active carbon filters isolate the operator from toxic inhalations during phytosanitary treatments, for a healthy and safe working environment.
K90 tractors come with a 3.8 lt Kubota engine which develops 75 HP. Devices such as the Exhaust Gas Recirculation system, the Diesel Oxidation Catalyst and the Diesel Particulate Filter dramatically reduce toxic substances emitted into the environment.
The latest generation Common Rail engines ensure a precise injection control, a more efficient combustion, improved performance and less fuel consumption
The electronically-managed engine keeps engine speed steady and thus the vehicle speed, the PTO rotation speed and the hydraulic flow, with following fuel saving and improvement of the work efficiency.
The engine speed electronic management, developed in-house by BCS Group, is fast and precise through a control panel located at the right of the steering wheel.
The transmission of the K90 range features the exclusive OS-Frame: engine and clutch are reciprocally connected by a single shaft transmitting movement both to the gearbox main clutch and the PTO clutch, obtaining compact dimensions and larger steering angles.
A joint in the middle of the tractor give more stability on slopes and all soil conditions, keeping the highest traction on all four wheels.
The synchronised gearbox is formed by 4 ranges and 4 speeds, for a total of 16 ratios both in forward and reverse, with synchronised reverser.
The logic sequence of speeds (from 700 m/h to 40 km/h) allows the selection of the best gear for the required use, with following fuel saving, reduced stress on mechanical components and a better quality of the work.
Transmission can be equipped with the electronically-operated reverser, with EasyDrive® electronic handling. The comfortable lever on the left of the steering wheel allows the operator to reverse the driving direction without lifting the hands from the steering wheel and without using the clutch pedal, while keeping the vehicle control at all times.
LONG LIFE CLUTCH
The new electronically-managed multiple-disc clutch in oil bath is smoother to engage and more performing vs the standard dry clutches, so that the operator can control the tractor always with more precision.
The use of this evolved hydraulic clutch inside the transmission generates a series of concrete advantages: longer life, no maintenance and top manoeuvrability thanks to the more compact dimensions of the tractor.
The clutch engaging pedal comes with the Pro-Act System for a more comfortable and ergonomic movement of the foot on the pedal. The operator is more sensitive to modulation.
The hydraulic system has two circuits with independent pumps and heat exchanger for oil cooling.
The oversized flow rate of pumps allows all modern implements for specialised agriculture to be coupled.
The new electronically-operated joystick allows to control the hydraulic system and the lifts at the same time through a single device; in this way, all operations involving the tractor hydraulic system can be performed safely and easily.
The rear PTO, with multiple-disc clutch in oil bath is independent from the transmission and is synchronised with all progress speeds.
A performing front lift is available as an optional, indispensable for using multipurpose implements.
The use in full safety both slopes and crosswise is guaranteed by the design geometry of K90 tractors, having a low centre of gravity and a very good weight distribution on axles when the implement is coupled to the rear lift.
The differential lock is electrohydraulically operated, so that the tractor is always under traction.
Four disc brakes in oil bath intervene simultaneously and continuously on all four wheels, even when the front drive is released, as they are supported by a hydrostatic control acting as braking divider.
The independent Brake-off parking brake is exclusive to K90 range: it automatically engages when the engine is switched off.
ALL UNDER CONTROL
The new, automotive-inspired dashboard is a concentrate of digital technology.
In addition to the electrohydraulic controls located in a logic and ergonomic way, the multifunction colour display keeps each parameter under control at all times.
The quick and immediate reading of the values is possible thanks to the analogue gauges with dials.
