Single beam chassisMade of high quality steel with a diameter of 160 x 160 mm, the main beam of the Tetra resists torsion effects to give a long working life. Being closer to the tractor, the machine’s centre of gravity is more centralized. This makes lifting easier and improves balance on the road.
Highly resistant swinging pivotsThe vibrocultivators are equipped with pivot bars which allow the elements to swing. They are made of solid HTS steel (high yield strength) to provide flexibility to the lift and resistance to wear.
Components parallel to the groundOnce you have set the Tetra’s level, you can adjust the various working components. They are all 1.5 m wide and are independent. With the parallelogram and the swinging pivot, you can follow the field perfectly.
Adjustable levelling bladeRear-facing, the position prevents accumulation of earth. It is equipped with small depth-adjustable tines that trim and level the ground. Spring-mounted and mechanically or hydraulically height adjustable, it adapts easily to conditions.
Hydraulic lockingFor greater safety during storage and transport, the frame is fully locked by a balancing valve on the jack. This prevents the machine from opening accidentally. No additional handling is necessary to (un)lock the machine.
Maintenance-free rollerThe Rotoherse side cover prevents small ridges forming between the roller elements to give uniform levels. Positioned inside the roller, the bearings are protected from splashes.
