Hawk PTO Multiplier — Tractor PTO to Pump Drive

The Hawk PTO Multiplier is a purpose-built speed-increasing gearbox that converts a standard 540 RPM tractor power take-off into the 1,080 RPM drive speed required by Hawk NLTI series triplex plunger pumps. Manufactured by Leuco S.p.A. in Italy under the Hawk brand, this compact unit eliminates the need for a separate engine or electric motor — your tractor becomes the power source for a fully mobile high-pressure washing system. AES Waterblasters supplies the PTO multiplier as part of complete tractor-mounted wash-down packages throughout New Zealand.
