Thor L80 | K105 RS

Isodiametric tractors, monodirectional or reversible, with steering wheels. Stage 3B engine, 75 or 98 HP

The Thor L80 and K105 RS are multi-purpose specialized tractors, particularly performing in vineyards, orchards, nurseries cultivations and greens maintenance

The low centre of gravity, the all-wheel drive and the rigid frame with front-wheel steering provide outstanding stability and unmatched road grip, allowing Thor L80 and K105 RS to work in complete safety both on flat and uneven, sloping grounds.

The reversible driving position (available as optional) allows to operate practically and rationally both with towed and front attachments.

The new electronically-operated Stage 3B engines comply with the strictest European standards as for emission control: a supremacy among isodiametric tractors translating into lower consumption, less toxic emissions and higher operating comfort.  

Innovative technical content, elegant design and reduced overall dimensions make Thor L80 and K105 indispensable machines for future agriculture.

Thor L80 tractors have a 2.4 lt Kohler engine which develops 75 HP. Turbocharged by a Turbo Intercooler, it is equipped with an EGR system alongside a DOC catalyst to reduce emissions and enhance operational efficiency.

Thor K105 tractors come with a 3.8 lt Kubota engine which develops 98 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. 

Both 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.

Transmission and gearbox

The transmission of Thor L80 and K105 is fitted with the OS-FRAME chassis

The structure with cantilevered engine allows for a very low centre of gravity without sacrificing ground clearance. 

The joint in the middle of the machine lets the front axle oscillate up to 15° with respect to the rear axle, for excellent stability on slopes, as the four wheels are always stuck on the ground.

The 32-speed synchronised gearbox (16 FWD + 16 REV) with synchronized reverser always allows right gear selection for the tasks for which the tractor is intended to.

The 'Long Life' clutch is multidisc in oil bath and requires no maintenance.

The Thor L80 and K105 are equipped with planetary gear axles to minimize wheelbase of the tractor and increase its manoeuvrability.

The permanent 4-wheel drive allows exploiting the machine’s towing feature.

Active and passive safety

The use in full safety both slopes and crosswise is guaranteed by the design geometry of Thor L80 and K105 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 braking system with multi disc wet brakes, act on the rear transmission.

Front and rear differential lock, electro-hydraulically controlled, allows the tractor to be always in traction.

The roll-bar and the safety belts on the seat protect the operator.

Driving position

The Thor L80 and K105 driving position is custom-fitted on the driver with ergonomic controls placed to be easily found and activated by the operator.

From the seat the operator enjoys a complete view both on the machine and on the attachments.

The hydrostatic steering ensures maximum maneuverability and low turning radii.

In the reversible version, a few seconds are required to rotate by 180° the seat, the steering wheel and the console so that the operator may work having the equipment in front of him and constantly be able to control the operations.

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.
