Boom sprayer transcript
The Australian Pesticides and Veterinary Medicines Authority Operating Principles in Relation to Spray Drift Risk has changed the way farmers and spray contractors like myself have to approach spraying. This places more responsibility on the chemical user to ensure the chemical reaches the target area, and not impacting the off-target area.
In this video we look at the changing face of boom spray technology, how to prepare for a successful job and provide some innovative tips to manage and mitigate spray drift. There are a series of checks required before any spray job is undertaken to ensure the sprayer is working properly. Make sure the shaft guard is in place over the power take off.
Check for any leakage in the pump and also check the oil levels if it is an oil bath pump. Check that the lid seal is in place so that the chemical mix won't splash out of the tank when travelling over uneven ground. Check that the sight glass is working and visible so you get a good approximation of the tank volume going in. Cleaning of filters or decontamination is very important.
We turn the main tank off so there will be no fluid coming from the main tank through the filter. We'll undo the fly nut from the filter body, removing the filter housing and filter cartridge, checking the filter cartridge for any damage, splits, cracks and also any potential residue from water or a chemical that's on there.
The next part of the filtration we look at is the main delivery line filters; primary and secondary. We'll pull both of these off, again inspecting the filter cartridge for any splits or separations along where the plastic is fused to the screen, checking for any excess residues and/or contaminants that may be down in the body of the filter.
Check for leakages and kinks in the hoses on the boom lines. Turn the sprayer on and off, making sure there's no dripping nozzles and that the check valves are working properly.
