The ZETA 40 VAGR3/4 brings the ZETA series’ horticultural spray performance to a petrol-powered package, using a gear reduction box on the pump’s VA face to suit a 3/4 inch shaft from a 4–6.5 HP engine. It delivers 44 L/min (10.5 GPM) at up to 20 bar (300 PSI), enough for orchard and vineyard boom work without needing a tractor PTO. At 36 lbs it suits a self-contained spray cart or trailer running its own small petrol engine rather than tapping into tractor power.
