Working width setting | Stone protection


Mechanical stone release with shear bolt

The shear bolt is the proven standard solution. Under load, the shear bolt snaps off at the predetermined breaking point and the plough body gives way to the obstacle by swivelling upwards. Raise the plough, insert a new shear bolt and off you go. The high release forces of the shear bolt allow operation also in heavy and hard soils.

The advantages:

  • Double action shear bolts
  • Hardened flange plates
  • High-quality shear bolts; in 10.9 quality

Semi-automatic as an alternative for the Cayros M

With the semi-automatic stone release system, the plough body swings out of the way by overcoming the strong pressure exerted by the two coil springs. For the Cayros M, this system is a viable alternative to using shear bolts or the non-stop stone release system when the ground is not excessively stony.

The advantages:

  • Low additional weight over and above a shear bolt protection system
  • Adjustable release force

Cayros S with NonStop stone safety device

The hydraulic NonStop stone safety release features, in principle, one hydraulic cylinder per plough body with each one directly connected to a nitrogen-filled hydraulic accumulator. When triggered, the plough body pushes a piston into the accumulator via the hydraulic cylinder. The gas is compressed and automatically returns the body to its initial position after passing the obstacle. The NonStop stone safety device is available for the smallest ploughs and for the large models.

The advantages:

  • Simple adaptation of the release force
  • Smooth and material protecting operation
  • Exchangeable ball joints and sockets
  • As standard, with additional shear bolt
  • The trip forces decrease as the lift height of the released plough body increases

NonStop stone release – Version 1

Central hydraulic accumulator on the hydraulic ram

In its simplest version, the hydraulic accumulator is directly combined with the hydraulic cylinder forming a compact unit.

The advantages:

  • The plough bodies release completely independently of each other
  • The plough bodies can be pretensioned differently
  • No hydraulic hoses or pipes on the plough beam

NonStop stone release – Version 2

Hydraulic accumulators with inter-connected pipework

Via the connection of the individual components, the release force can be also adjusted centrally across all the bodies. An isolator valve on each hydraulic accumulator means that the setting on each plough body can, from choice, also be set independently to different pressures.

The advantages:

  • The adjustment of the release force is carried out across all plough bodies in just one step (even whilst on the move)
  • Similar pipe cross-sectional area means that each furrow has only a slight influence on each other

Cayros – Mechanical precision

The standard furrow width adjustment can be altered in 4 steps by manually pivoting the leg fixing consoles. In this way, the plough can be easily adapted to different applications (soil conditions, tractor, etc.). When the furrow width is adjusted, all the soil-engaging metal and support wheels are also automatically adjusted.  No additional correction is necessary.

Cayros V – Comfortable hydraulic operation

The furrow width can be smoothly and hydraulically adjusted from the tractor in all Cayros V ploughs. A very clearly visible display, consisting of a scale and indicator, keeps the driver informed about the furrow width setting. The integrated kinematics of the Cayros V also automatically set the draft point, the front furrow width, all the soil engaging tools and the support wheel.

The advantages of the Cayros V

  • Easy adjustment with automatic adaptation of the front furrow, the draft point and accessories when adjusting the furrow width – no manual correction required
  • The optimised lever design of the pivot points ensures a low adjustment force and bearing load, thus reducing wear and tear and resulting in a longer service life.
  • The pivot points of the leg holder are outside the beam, so that any weakening of the box section due to additional drill holes is avoided.
  • Minimal pivot points result in minimum wear and tear and reduced maintenance requirements.
  • The use of CONNEX bushings ensures a longer service life
