Isodiametric tractors, monodirectional, with central articulation. 26 or 35.6 HP
Cromo K30 | K40 AR are new design tractors produced to satisfy the requirements of hobby-farmers and small farms specialised in growing in greenhouses, nurseries, small rows of vines and poultry holdings.
Thanks to the isodiametric wheels and steering with hydrostatic drive acting on the central articulation, the best qualities of the Cromo K30 | K40 AR is its agility and manoeuvrability.
The double ellipsoidal lights integrated in the bonnet give the tractor a particularly refined look.
Two Kubota engines are available for the Cromo: a 26 HP three cylinder engine (Cromo K30) and a 35.6 HP four cylinder engine (Cromo K40), both with indirect injection and natural aspiration.

TRANSMISSION AND GEARBOX
The transmission of Cromo K30 | K40 is fitted with the OS-FRAME chassis. A 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 and maximum traction.
The gearbox with easy gear engagement has 8 forward and 4 reverse speeds, without speed overlapping.
The dry single disc clutch grants gentle and immediate gear connection.
The distribution of the weights on the axles, 40% on the rear and 60% on the front, is proved optimal once the rear lifting equipment is mounted. The rear load optimises the sharing of the weights on the two tractor axles to increase stability and safety.
The permanent 4-wheel drive allows exploiting the machine’s towing feature.
PTO AND HYDRAULIC SYSTEM
The rear power take-off is at 540 rpm with mechanically engaged and disengaged. It can be standard or synchronised with the gearbox for operating self-propelled trailers.
The rear hydraulic lift by rams is set up with a cat. 1 three point connection, complete with stabilisers to restrict the equipment spinning laterally. The two lower arms of the lift are fixed and their vertical tie rods can be manually adjusted, like the third point tie rod.
The hydraulic system has a gear hydraulic pump with flow rate of 16.5 l/min and max. pressure of 125 bar supplying the steering system, the rear lift and the remote control valves.
ACTIVE AND PASSIVE SAFETY
The efficient service brakes, drum type acting on the front wheels, guarantee modular and completely safe braking.
Front and rear differential lock, mechanically controlled, allows the tractor to be always in traction.
The roll-bar and the safety belts on the seat protect the operator.
The driving position is custom-fitted on the driver with ergonomic controls placed to be easily found and activated by the operator.
The gear levers are positioned beneath the dashboard for maximum driving position accessibility.
The hydrostatic steering ensures maximum maneuverability and low turning radii.
