Working Depth

Working depth adjustment through the articulation of the wheels, driven by the tractor's hydraulic system. The depth amplitude is determined by the quantity of course limiter wedges, located in the shafts of the two hydraulic cylinders.

Rigid Chassis System

The HEAVY DUTY model has as a characteristic the coupling of the furrower sets to a rigid chassis, supporting greater work effort and providing more rigidity and reliability to the system in harder soils.

Subsoiler Arm

With an exclusive arm, point and shank set, manufactured in special cast steel alloy, increasing its resistance to abrasion and decreasing the need for tractor power. It has an automatic arm disarm and rearm system (return via pressure accumulator). Without causing excessive revolving, it keeps most of the plant residues on the surface, improving porosity and water infiltration. The subsoiling arms have adjustable adjustment for product direction, with 5 positions (needs lime in dry condition and free of impurities).

Arm tip

It has specific geometry for the scarification work, made of cast steel with special alloy and heat treatment that gives it high resistance to wear by abrasion.

Cutting disk

Standard cutting disk diameter of 20 inches, with a helicoidal spring that allows the disk to follow the ground undulations. Its mechanism offers greater cutting effectiveness without compromising the working depth of the arm.

Reservoir

Manufactured in fiberglass of great capacity and equipped with a grain-breaker grid.

Limestone blowing system

Via positive pressure turbine, with hydraulic drive of rotation between 3,500 to 4,000 RPM (it requires continuous hydraulic flow of at least 21 l/min).

Limestone distribution system

With stainless steel belts, in opposite movements, ensuring uniform dosing between the lines and preventing limestone build up in the tank.

Clod-breaking Roller

Follows the topography of the land, reducing the size of the clods and leveling the surface of the worked area. It is equipped with bearings in oil bath, articulated supports and helical springs to ensure the stability of the set.

Transmission

By gears, of easy handling and fast dosage regulation.

Hydraulic lifting

Driven by hydraulic cylinders with safety valves, preventing the equipment from falling suddenly due to system failure.
