Ocmis R4/2A Turbine Drive Hard Hose Irrigator

Overview

The Ocmis R4/2A is a hard hose reel travelling irrigator manufactured by Ocmis Irrigazione, a leading Italian irrigation equipment producer renowned for engineering excellence and innovation. This model represents one of the best-selling units in the Ocmis range, combining robust construction with high-performance capabilities and remarkably low running and maintenance costs. Designed for professional agricultural operations, the R4/2A delivers reliable irrigation across a wide range of field conditions, with hose configurations spanning from 100mm to 140mm diameter and lengths extending from 300 to 600 metres to suit diverse farm requirements.

What distinguishes the R4/2A from conventional travelling irrigators is the proprietary Turbo Speed system, an innovative technology that significantly reduces turbine load loss while enabling access to multiple machine speeds even under very low flow rates and inlet pressures. This engineering advancement ensures consistent performance across varying water supply conditions, making the system exceptionally versatile and user-friendly. The machine features a 4-speed gearbox, power take-off capability, and comes equipped with either REFLEX or EXPLORER rainguns depending on configuration, with comprehensive nozzle sets to optimise water distribution across different irrigation scenarios.

Key Features & Benefits

• Turbo Speed System: Proprietary technology reduces turbine load loss and maintains consistent machine speeds even with low flow rates and inlet pressures, ensuring reliable performance across varying field conditions and water supply scenarios.
• 4-Speed Gearbox with Power Take-Off: Provides precise speed control for optimal water application rates, allowing operators to match irrigation speed to crop requirements, soil infiltration rates, and field topography for maximum efficiency.
• Hydraulic Trolley Lifting System: Telescopic hydraulic feet with integrated pump enable easy positioning and levelling of the machine, reducing setup time and ensuring stable operation on uneven terrain without manual labour.
• Hot Galvanised Chassis and Turret: Superior corrosion protection extends machine lifespan significantly, particularly in challenging environments with high humidity, coastal conditions, or aggressive water chemistry, reducing long-term ownership costs.
• Dual Raingun Options: REFLEX rainguns with nozzles from Ø24 to Ø32mm suit medium-flow applications, while EXPLORER rainguns with nozzles from Ø28 to Ø40mm handle higher flows, providing flexibility to match machine configuration to water availability and field size.
• Premium Polyethylene Hose: Manufactured from unadulterated raw material ensuring durability, UV resistance, and long service life without degradation, maintaining consistent flow characteristics throughout years of seasonal use.
• Galvanised Raingun Trolley on Variable Track Wheels: Adjustable track width accommodates different crop row spacing, while galvanised construction resists corrosion, ensuring smooth travel and minimal crop damage across the irrigated area.
• Comprehensive Instrumentation: Tachometer monitors machine speed, glycerine-bath pressure gauge provides accurate operating pressure readings under vibration, and speed equaliser maintains consistent travel speed for uniform water application.
• Safety Guards and Stabilisers: Steel safety guards are swaged, galvanised and painted for protection, while drawbar stabilisers ensure safe towing and positioning, meeting international safety standards for agricultural machinery.
• Low Maintenance Design: Turbine flanged directly on gearbox with built-in bypass, flexible connection pipe, and quality component selection minimise wear points and servicing requirements, reducing downtime and operational costs.

Ideal Applications

• Large-Scale Row Crop Production: Ideal for irrigating extensive plantings of maize, cotton, soybeans, vegetables, and other row crops where long irrigation runs and reliable operation maximise field coverage with minimal repositioning.
• Pasture and Fodder Crop Irrigation: Excellent for irrigating grasslands, alfalfa, and forage crops where uniform water distribution across large rectangular fields ensures consistent growth and maximises yield for livestock operations.
• Cereal and Grain Production: Well-suited for wheat, barley, and other cereal crops requiring consistent moisture management across expansive fields, with adjustable application rates to match critical growth stages.
• Orchards and Permanent Crop Systems: Smaller configurations work effectively in tree crops and vineyards where controlled irrigation between rows is required, with variable track width accommodating different planting spacings.
• Contract Irrigation Services: Robust construction and low maintenance requirements make this model ideal for contractors servicing multiple farms, with the versatility to handle diverse field sizes and crop types efficiently.
• Operations with Variable Water Supply: The Turbo Speed system's ability to function effectively under low flow and pressure conditions makes this machine particularly valuable for farms with inconsistent water availability or limited pumping capacity.
