Tyrok semi-mounted reversible plough

Tractors using wider tyres, as well as crawler tractors, can be used for on-land ploughing. This reduces the ground pressure in the deep ground layers and prevents plough pans. In addition, GPS steering systems can be used when on-land ploughing. This provides greater comfort for drivers and also ensures a precise match-up to the next furrow.

Advantages of the front guide wheels 

• Reliable depth control on unmoved or solid ground 
• Manual setting only required when changing the working depth
• High self-driving effect

If the optimum on-land ploughing conditions are not present, because of the soil surface being too wet, you can quickly change over to in-furrow mode. The levers on the turnover arm for the changeover are very easy to reach and need only to be actuated once between modes. The swing-arms don’t then need to be fixed or pinned and the front support wheels also no longer need to be set.

Thanks to its two-stage end-position damping, the plough’s turnover process is slowed down shortly before reaching the end of its travel. This results in a damping effect which reduces stress on the plough structure when the cylinder is retracted. There is no need to make any compromises here as the stress-free turnover process is completed within a very short period. An additional highlight is the automatic centre of gravity reduction when turning the Tyrok On-Land over. The low centre of gravity when turning increases the stability and provides better weight distribution on the lower links. 

1. Extending the cylinder
2. The swing-arm is pushed forward
3. This results in the centre of gravity of the plough moving downwards
