Antonio Carraro | Plus | ACTIO


AC Full Chassis with Oscillation - cast iron full chassis hosting the tractor's transmission. with a central articulated joint which allows a longitudinal oscillation up to 15°; this system allows the tractor to keep up with the soil's sinuosity ensuring constant traction and grip.


RGS™ Rev-Guide System, is the AC reversible driving system on a rotating turret which inverts the driving direction in just a few seconds in order to work efficiently with towed or frontal equipment. Simply turn the seat/steering wheel/dash/pedal assembly 180° for an identical, but reverse, driving direction.

Steering wheels

The short wheelbase and tight steering radius make the tractor extremely agile in crop rows. To further reduce the turning radius, the steering* brakes can be utilized, while accentuating the steering effect obtained thanks to the double-acting constant velocity joints.

Grass cutting and collection

The RT 1500 HDS* is a professional turbine rotary mower equipped with an innovative system that allows the cutting height to be adjusted in a simple, intuitive manner. The powerful suction turbine fitted onto the deck in mid-centre position ensures efficient collection of the grass clippings without clogging. The turbine features six curved vanes arranged in such a way as to ensure a fluid, clog-free flow of the cut material, including wet grass. The three rotary cutter blades are arranged in a triangular fashion under the deck providing a uniform and precise cut. Featuring a compact design and a smooth and clean shape, the mower has a cutting width of 150 cm and enables working close to kerbs and pavements. A pressure gauge allows the operator to monitor the turbine operation by constantly checking the suction efficiency and the grass level within the collector. The RT 1500 HDS can be placed in vertical position without the need to remove the cardan joint. This operation can be easily performed by only one operator. 


CT 1000

The patented CT 1000* collector has a capacity of up to 1000 litres ensuring a long operating time. This exceptional holding capacity is due to the optimal weight distribution on the ACTIOTM chassis, resulting in outstanding balance and stability. Made from shock-proof and corrosion-resistant fiberglass, the collector has a compact, rounded design that allows the machine to manoeuver easily even in the most cramped spaces. The cut grass is easily discharged by simply activating the remote valve lever (or the joystick controller), after pointing the discharge opening in the desired direction at a maximum height of 2.15 m.  This operation may only be carried out with the machine at a standstill. The CT 1000 collector can be fitted and removed with ease by simply screwing/unscrewing the four fixing screws.
