The Hardi NL and NV Series of sprayers feature tank sizes of 650, 850 and 1000 litre sizes. The polyethylene tanks are carried in a strong powder coated steel frame. The Hardi diaphragm pump delivers 99 litre per minute and delivers through a Hardi BK control unit that has pressure equalisation that maintains constant pressure if one or more boom sections are turned off. The tank has pressure agitation. Boom sizes are 6, 8 & 10 metre in the SB range and 10 & 12 metre in the heavier MB range. The 800 & 1000 litre series of sprayers have hydraulic folding 12 or 16 metre booms with hydraulic height adjustment. Electric valves are standard on the NV range.
