Turn the crop task into a machine brief
Describe the crop, row spacing, access, area and available refill points. State tank capacity in L, liquid flow in L/min and application rate in L/acre or L/ha with the intended nozzle setting. Identify whether air assistance is required and ask how the supplier measures air output. Pressure figures without a nozzle and measurement condition do not establish a comparable application result.
Include carrying weight when filled, harness adjustment, shutdown controls and the intended liquid. Compatibility must be confirmed for the tank, hose, seals and wetted components. A general material name alone cannot establish compatibility with every formulation.
