Kverneland has launched its smallest Siloking self-propelled feeder to sit on a conventional chassis design.

Part of the Selfline 4.0 range, the System 300+ comes in four capacities – 19, 22, 25 and 27cu m – and fills a hole between the tricycle rear-steer machines at 13-22cu m, and the larger System 500+ and System 1000+ from 19-32cu m.

Power comes from a 218hp Volvo engine mounted to an air-suspended chassis that offers four-wheel steering and a 25kph top speed.

At the front is a 2m-wide milling head that feeds the mixing tub via a 700mm-wide conveyor belt. Inside the tub are twin vertical augers with adjustable knives and discharge is via a cross-conveyor or rear doors.

The cab features a 7in colour screen displaying functions including discharge door position, mixing speed and weighing data, with Siloking’s programmable weighing system included. Up to four cameras can be hooked up to view mixing, discharging or help with reversing.

An optional chopper behind the milling head could be useful for those dealing with large straw volumes and is available across all models in the Selfline 4.0 range. Chop lengths are said to be about 20-40mm with this addition.

Height for the System 300+ ranges from 2.9m to 3.53m depending on the tub size. Width is 2.54m and length is between 8.9m and 9.4m.

List prices start from £249,104 for the 19cu m model.
