Tyrok semi-mounted reversible ploughs

The rectangular beam with the dimensions 200x150x10 minimises any bending of the frame, even under heavy load and hard soil conditions. The rigidity of the beam stops any bending, thereby ensuring the furrow depth remains constant across the entire furrow width. The rectangular profile also increases the load carrying capacity of the beam. The beam height is 80 cm. 85 cm is also available as an option on ploughs with shear bolt overload protection.

The key advantages:

• Extremely stable beam thanks to the over-dimensioned box section
• Comfortable and gentle turnover
• Safe and comfortable transport travel
• Constant furrow depth of all bodies thanks to the rigid beam
• High flexibility in the number of furrows
• Beam height 80 cm (85 cm as an option with shear bolt overload protection) 

High flexibility
The simple yet strong design of the Tyrok enables the use of an extendable beam system. This means that an additional furrow can be removed or added in next to no time.

The hydraulic overload protection is basically a hydraulic cylinder with a directly connected, nitrogen-filled hydraulic accumulator on each pair of plough bodies. 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. A choice can be made between the standard hydraulic protection with decentralised adjustment or the optional protection with central adjustment for convenient and quick adjustment of the release pressure of all bodies.

The benefits

• Simple adaptation of the release force
• Smooth and material protecting operation
• Exchangeable ball joints and sockets
• As standard, with additional shear bolt

Shear bolts are the tried and tested 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. The high release forces of the shear bolt enable use even in heavy and hard soils.

The benefits

• 6,200 kg shear force
• Clean shear-off due to the double-cut, hardened flange plates

The pressure acting on the plough bodies is determined by many different factors. The correct release pressure is of great importance so as to ensure that the body sits firmly in the ground, but no stones are ploughed up. This can be comfortably set with the hydraulic overload protection. Unlike some other manufacturers, the release pressure decreases as the lift height increases. A gentle return of the body into the ground without damage can thus be ensured.
