The challenge in terms of the fuel consumption of a diet mixer is the start-up torque, which is typically twice that of the requirement during the mixing itself. The situation occurs when the auger is stopped, and the feed settles around the augers.
The new 4-speed transmission for Kongskilde JF diet mixers solves this because the mixture can be "lifted", using one of the low gears. It then shifts into a higher gear, without the tractor transmission being overloaded. The need for an actual start-up gear has become topical with compound feeds, which nowadays can weigh more than 20 tons. The fourth and highest gear ensures complete emptying of the feed mixer.
The two middle gears are used for mixing; the gear selection can be adapted depending on the size of the tractor and feed density. A higher gear is often selected to prepare lighter mixes for young animals. This allows running with low engine speeds, which reduces fuel consumption. Toggling between the four gears is hydraulic and controlled by a wireless remote control, which allows free skipping between the gears.
After recent test-marketing, the new Mix+ wear-part concept for Kongskilde JF complete diet mixers is now introduced. In particular farms with large dairy herds have embraced the concept, which enables the replacement of the edges of the mixing auger. In this way, the edges can be kept intact, without the costly replacement of the entire mixing auger. The result is improved feed quality and lower operating costs.
The Mix+ kit consists of a number of wear plates, which together with the knives are bolted to the auger flights. The idea of replacing the wear parts was taken from the ploughs, the shares of which are also exchangeable as wear parts. The wear plates are made of 4 mm stainless steel in the extremely durable 304 quality. Kongskilde is the first on the market to offer such a concept for complete diet mixers.
