Stronger and stronger, faster and faster: High productivity pressure in agricultural engineering

Currently agriculture provides about 7.3 billion people worldwide. 20 years from now these will most probably be 8.5 to 9.8 billion people, but farmland will not increase. This explains in simple words that agriculture is under high productivity pressures.

Agricultural machines become more powerful, their operating width and speeds are rising. IT-supported "Precision Farming" is part of everyday life, tractors, combine harvesters, haulers and others will soon be on the way in the field without any driver. At the same time agricultural machines have to comply with stricter and stricter emission standards.

KTR has decades of history as a development partner and supplier of manufacturers of agricultural machinery, providing a wide product portfolio for this industry. Flexible flange couplings in various designs connect I. C.-engines and hydraulic pump(s) or splitterbox. In agricultural machines driven with a front PTO shaft such as milling machines, crop protection sprayers and mixer-wagons, jaw couplings are continuously operating under severely adverse conditions (moisture, sand, fertilisers, high mechanical load). The coolers for agricultural engineering developed by KTR serving for engine cooling are essential components in the cooling circuit even under extreme conditions.

With most projects in agricultural technology our business units „Engineered and Core Business“ cooperate with the customer already during the development stage. The design engineers‘ standard tasks comprise FEM calculations, coupling selection in accordance with DIN, e. g. DIN 9611, torsional vibration analysis and the calculation of cooling capacity on consultation with the engine manufacturer.  

Couplings for agricultural machinery

Our range of couplings for agricultural machines includes flexible jaw and pin & bush couplings as well as torsionally stiff and highly flexible flange couplings for high performance and smooth operation even under adverse environmental conditions.

Coolers for agricultural machinery

Our compact and high-performance coolers for agricultural machines: available as tailor-made multimedium coolers and oil/air coolers as a standard solution.

Coupling for agricultural machines with PTO shaft acc. to DIN 9611

The KTR coupling ROTEX ZR installed in a manure spreader. The coupling serves as a connection to the gearbox in the PTO shaft drive train.
