    Overview

    The Ocmis R4/1A is a hard hose reel travelling irrigator manufactured by Ocmis Irrigazione, Italy's premier irrigation equipment specialist. As one of the best-selling models in the Ocmis range, this robust machine delivers exceptional performance for medium to large-scale agricultural operations, combining versatility with user-friendly operation. Available in nine different hose configurations ranging from 100 mm to 140 mm diameter and lengths from 260 to 500 metres, the R4/1A provides flexible irrigation solutions for diverse field sizes and crop requirements.

    What distinguishes the R4/1A is the innovative Turbo Speed system, which reduces turbine load loss whilst simultaneously enabling a wide range of machine speeds even with very low flows and inlet pressures. The 4-speed gearbox delivers precise control over irrigation speed and application rates, whilst the turbine flanged directly on the gearbox with built-in by-pass ensures efficient power transmission. With hydraulic telescopic feet for easy positioning, a hot galvanised chassis for superior corrosion resistance, and compatibility with both REFLEX and EXPLORER rainguns, this travelling irrigator represents a comprehensive solution for professional growers seeking reliable, low-maintenance irrigation equipment.

     

    Key Features & Benefits
