Knight Farm Machinery has announced that its stand at Cereals will include the Vario Select system, said to offer completely even spraying performance even when working on curved routes, around obstructions and on field margins.
It uses a combination of four different nozzles at each spray point to offer up to 16 different application rates, typically from 0-800 litres per minute. As the sprayer turns, a gyroscope measures the severity of the turn and adjusts spray rates accordingly.
This means that on the inside of the turn, where the boom is travelling slower, application rates are lowered, while they are increased on the outer side of the turn.
A simple, computerised nozzle selector allows the operator to dial in a target rate, droplet size, minimum and maximum pressures, and the working speed.
“They can also ask the system to recommend the best choice of nozzles for any particular job,” said Brian Knight.
“It enables the machine to ‘spot spray’, with the volume of spray applied being changed according to the severity of the weed, pest or disease problem.”
Visitors to the stand will also be able to see the Active Rinse system, which provides fresh water to key parts of the sprayer to ensure the efficient use of chemicals, while also minimising the amount of chemical solution throughout the plumbing.
At the end of operations, the system can flush the pipework with clean water and return the washings to the main tank to make travel between fields much safer. An optional air blow out can evacuate all liquid from the pipework to offer an extra level of protection.
The system meets an urgent need added Mr Knight: “The NSTS testing scheme continues to report leaks and drips as the leading fault in sprayers being tested, and unlike other faults, the level of problems is not reducing.
“Customers report that the system, which can clean and flush the sprayer at the end of each tank load, can help prolong the working life of the sprayer, help cut the risk of leaks and drips and help farmers meet their environmental commitments.”
