Crop lifter
Crop lifters have a long tradition at Schumacher.

Today, crop lifters are essential in the harvest of different crops such as cereal and soybean.

Planetary high-performance knife drive
The Pro-Drive planetary drives generate an absolutely linear stroke length. Force progression and knife movement are just as linear. The driving force available is fully converted to lifting force, which especially under difficult harvesting conditions preserves the power of the cutting system.
The vertical and horizontal versions offer high flexibility in terms of drive concepts.
