The plough beam tube has been optimised to absorb the loads acting on it during operation even better. To ensure the high strength of the beam, holes have been reduced to a minimum and arranged along the low-stress beam centreline. The beam material and strength are not compromised unnecessarily as a result. That is also the reason that the body mountings are also located outside the frame tube on ploughs equipped with hydraulic furrow width adjustment.
The large-dimensioned main beam section ensures smooth transmission of the pulling power from the headstock and beam link to the plough beam. The main beam section extends from the first to the third plough body and is bolted to the plough beam on both sides by a bolted reinforcement bar. This increases strength without squashing the beam profile.
The turnover mechanism on SERVO hitch-mounted reversible ploughs features a turnover shaft and a large-dimensioned turnover unit. Due to the wide bearing spacing and the large taper roller bearing, the forces on the bearing are reduced. In addition, the turnover shaft is designed as a hollow shaft and serves as a lead-through for hydraulic hoses, providing them with the best protection against damage.
The steel casting of the turnover unit ensures a high material quality for a long service life. The turnover unit is generously dimensioned to reduce the forces acting on the bearings. A double-sided lug on the turnover cylinder distributes the turnover force evenly. The bearing journal for the turnover cylinder is a forged component and integrated over a large area into the headstock tower.
The large dimensioned beam link is made of high quality cast steel and is slightly curved. This ensures high strength and durability. The curved cast beam link provides more space for the front furrow to give the SERVO a wide range of front furrow adjustment. This makes it adaptable to a wide range of tractors.
The beam angle lift spindle is enclosed within the beam angle lift guide. Thanks to the enclosed design, the spindle is protected against contamination. Easy adjustment is guaranteed at all times.
In addition, stress on the turnover unit is prevented because the turnover cylinder rests on the beam angle lift during the turnover sequence.
For increased strength, the mounting brackets are bolted instead of welded. By deliberately avoiding weld seams, the material is not weakened at this point and retains its full strength.
To prevent overloading and possible damage, standard and PLUS models feature shear bolts. When the shear bolt is triggered, there is no transverse deformation of the bolt so it does not jam between the leg and the mounting, and no damage is caused. Easy replacement ensures that the plough is back in action quickly after the shear bolt has been triggered. This saves time and increases output.
