Krone fifth generation Big Pack balers are now available with a fully integral dispenser and rate control feature for silage or conservation additives. Applying additives efficiently can save costs. The unit can also be installed on other silage harvesting equipment.

The dispensing rate is controlled by using the weighing information from the bale chute or by entering the bale weight manually.

The dispenser system has a 400-litre tank that is mounted behind the yoke on the tube steel frame. The tank has a large filling opening with a sieve and labyrinth ventilation and a filling level sensor.

The additive pump has a three-way stopcock that allows operators to switch between the suction line to the tank and the rinsing line. An integral filter ensures the lines will not clog. A flow-metering sensor measures the current flow rate, while a gear pump in combination with two valves allows operators to select individual rates from 0.5-6.5 l/m.

The filling height is indicated on the cab-mounted terminal screen, and operators can pre-set whether and at which filling level an alarm is signalled. The pump is housed in an easily accessible box above the yoke where it is protected from dust ingress.

Several hoses are coupled behind the baler’s lamp bracket. A filling hose, a rinsing hose and a sump emptying mechanism make it easy to service the system. Four customary flat spray nozzles are installed behind the pick-up where they apply a uniform spray onto the material. Access to these nozzles is without tools, so replacing them by nozzles with larger outlets is easy.
