If we stand still, we go backwards. This aphorism is particularly true when it comes to making project cooperation a success. It is vital to think today about the innovations of tomorrow, and so GROUP SCHUMACHER considers research an essential element in its innovative processes.

For this reason, GROUP SCHUMACHER engages in a number of research projects with German universities and colleges, in which we explore new solutions that will shape the future for our customers. Drawing on our extensive expertise and great market proximity, we explore innovative harvest solutions and services that allow manufacturers, farmers and contractors to boost their profitability.

These are the research projects we are currently involved in.

Our products have proven their worth millions of times on harvesters around the world, either as OEM, retrofit or repair parts.

You will find us everywhere where farmers cut, chop and bale. We passionately attend to every detail for you to reap a successful harvest.

As an innovation driver in the areas of cutting, chopping and tying, we will take this level of innovation to the next generation of products. This is what sets us apart.

Stronger twine tying systems that bale more material

Because a well-shaped bale is the result of dependable knots with a high resistance to tearing. The twine must withstand high pressures when the bale expands as it leaves the chamber, and therefore the retaining force of the knot is essential. Two innovative milestones for high-capacity balers are presented by the Rasspe brand in our group:

  • The compact knotter allows machine manufacturers to arrange 8 rather than 6 individual knotters inside the knotter bay without requiring a wider machine.
  • The double loop knot combines the advantages of the loop knot with those of the double knotter, leading to a system that offers a substantially greater potential than any other tying system currently on the market. The system was awarded the DLG Innovation medal 2015.

Optimizing sugar cane blades

In conjunction with Cologne University of Applied Sciences, GROUP SCHUMACHER seeks to improve the cutting elements on self-propelled sugar cane harvesters. Harvesting sugar cane is a highly mechanized process at high work rates that inflicts heavy wear on the blades. By carrying out trials both at the lab and on fields in Brazil, we explore various designs and material options. At the same time, we scrutinize the manufacturing costs to meet the demands in the contractor parts markets. Our focus is on boosting machine productivity and reducing downtime as harvest is pressed for weather.

eHarvest - a fully electric cutter bar

In conjunction with Dresden University, Dresden Technical University and further partners, GROUP SCHUMACHER developed a comprehensive electric cutter bar system in which all rotary drives form an integral part. This design is expected to provide a more efficient powerflow and better control of the individual elements in the cutting system - especially on 30ft+ cutter bars. In addition, electric drives are compact by design and for the first time ever allow the cutter bar to communicate with the combine. The eHarvest project is extremely relevant in a world where work widths keep growing and combine manufacturers are pushing the limits of performance.

Hard-cover straw chopper knives - better longevity and straw management

Dresden Technical University and GROUP SCHUMACHER explore options to improve post-harvest straw management. As combine capacities increase, we look for new concepts to cut the straw to good quality chops and minimize the power input. Instead of distributing the straw actively, GROUP SCHUMACHER relies on a straw chopper of a different geometry which accelerates the flow throw the straw chopper and scatters it evenly across the swath. The design saves drive power within the combine and suits other applications as well.

Compensatory knife head

In combine headers, the power is transmitted from the knife drive, through the head bearing, and to the knife head and knife. The EWM Acrobat knife head creates the ideal connection, because it dynamically compensates for the building tolerances in all directions, and so the intended power transmission takes place. The Acrobat therefore allows an unconventional connection between the knife drive and the knife. This improves the utilization of the driving force and protects the knife drive and cutting system under pressure.

Study of crop lifter wear characteristics

Larger header widths, higher driving speeds and abrasive soils increase the wear pressure of the crop lifters in the sliding area. Improvements developed by Gebr. Schumacher are therefore aimed at customized driving dynamics and the stability of the crop lifter. The new WaveTrack sliding skid concept is based on the alteration of the skid in the wearing area. The wavy sliding area increases stability, without the need for costly surface coating processes to be carried out.
