This Berthoud table top sprayer has been designed so that the weight is evenly distributed over the tractor, with no water held on the rear of the machine. The tractor does not require extra weights and can be driven for longer distances on the road due to the balancing. The fan and pump unit are located at the rear of the machine.
The controls are positioned in an easily accessible place next to the dashboard of the tractor. The controls include an adjustable flow rate meter, a five boom section shut off, and break backs on the booms in order to prevent damage in the polytunnel.
The Berthoud duster is used to apply sulphur, and can be used on strawberries, hops or nursery trees. The duster has a range of between 4 and 8 metres width. It had a three point linkage and a 15 hp requirement.
