A mowing process that conserves the grass is the best basis for clean forage. Ultimately, this is about maintaining the correct cutting height of 6-8 cm. That is how crude ash ingress is reduced to a minimum right from the start of the harvest chain. Subsequent harvesting machines then do not have to work so close to the ground to collect the forage cleanly. At the same time, sufficient residual assimilation area remains for the grass to grow again more quickly.
If the areas to be mowed are not flat, it is particularly important that the mower can adapt well to the ground to maintain the set cutting height and prevent dirt entering the forage as the first cause of forage contamination.
Thanks to their unique ground tracking system, optimum weight alleviation of the cutter bar, and excellent cutting quality, our mowers give you the basis for a clean forage harvest and rapid regrowth of the plants.
Regardless of whether it is a front-mounted or rear-mounted mower, the mowing unit must be able to adapt independently to any undulations in the ground. This means that it has to have sufficient freedom of movement. With +22 ° / -30 ° on our side pivot mounted rear mowers and +/- 22.5 ° on our centre pivot mounted models, our mowers deliver perfect ground tracking.
For front mounted mowers, the trend is toward trailed designs due to their excellent ground tracking properties. That is why PÖTTINGER's ALPHA MOTION technology has been the market trendsetter since 2005 thanks to its three-dimensional ground tracking.
In connection with ground tracking, the weight alleviation of the mower unit is also an important factor. This must react quickly to any unevenness in the ground and at the same time guarantee a uniform cutting height even at high driving speeds. Whether the weight alleviation system is mechanical or hydraulic depends on the design and size of the mower, as well as the on-site conditions.
Regardless of whether front or rear mower unit with centre pivot or side pivot mountings, PÖTTINGER guarantees that in every situation the mower unit acts on the ground with the same pressure over its entire width while delivering excellent ground tracking.
The geometry of the cutter bar also contributes to ground tracking performance. The PÖTTINGER cutter bar, which is only 28 cm deep, tracks perfectly even on bumpy terrain. The extremely flat design with a height of just 4 cm also guarantees perfect forage flow. The streamlined leading edge of the cutter bar allows the soil to flow underneath, separating it cleanly from the crop.
The clamped mower blades create a tidy mowing pattern. They rotate very close to the surface of the cutter bar and the counter knife. This guarantees a clean and tidy cut even in damp and muddy conditions.
"We have 70 dairy cattle on our farm. The quality of the forage is very important to us and that’s why we take great care to make sure the mown crop is clean. The ground tracking of our PÖTTINGER rear and front mowers on our very hilly terrain is outstanding."
