Ocmis R4A Turbine Drive Hard Hose Irrigator

Overview

The Ocmis R4A is a premium turbine-drive hard hose irrigator manufactured by Ocmis Irrigazione, one of Italy's most respected irrigation equipment producers. As one of the best-selling models in the Ocmis range, the R4A combines robust construction with high-performance irrigation capabilities, offering hose configurations from 90 mm to 125 mm (3.54 to 4.92 inches) in diameter and lengths extending up to 570 metres (1,870 feet). Designed for agricultural professionals worldwide, this hard hose reel irrigator delivers exceptional versatility across diverse crop types and field conditions whilst maintaining remarkably low running and maintenance costs.

What distinguishes the R4A from conventional hard hose irrigators is the innovative Turbo Speed system, which significantly reduces turbine load loss whilst providing access to multiple machine speeds even under low flow and pressure conditions. The machine features a 4-speed gearbox flanged directly to the turbine with integrated bypass, offering precise control over retrieval speed and irrigation uniformity. With hot-galvanized chassis and turret construction, epoxy-coated reel, and polyethylene hose manufactured from unadulterated raw materials, the R4A represents Italian engineering excellence designed to withstand decades of intensive agricultural use.

Key Features & Benefits

• Turbo Speed Turbine System: Reduces load loss on the turbine whilst enabling variable speed operation even with low inlet pressures and flow rates, ensuring consistent performance across varying field conditions and water supply scenarios.
• 4-Speed Gearbox with Turbine Integration: Provides precise control over hose retrieval speed with the turbine flanged directly onto the gearbox and built-in bypass, allowing operators to match irrigation speed to crop requirements and soil infiltration rates for optimal water distribution.
• Hydraulic Telescopic Feet with Trolley Lifting: Equipped with hydraulic pump-operated feet and trolley lifting system, enabling quick, stable setup on uneven terrain and effortless repositioning between irrigation sets without manual labour.
• Hot-Galvanized Chassis and Turret: Superior corrosion protection through hot-dip galvanization of structural components ensures decades of reliable operation in humid agricultural environments, protecting your investment against rust and deterioration.
• Dual Raingun Options with Comprehensive Nozzle Sets: Includes either REFLEX raingun with nozzles from 24 mm to 32 mm or EXPLORER raingun with nozzles from 28 mm to 40 mm, providing flexibility to match precipitation rates to specific crop water requirements and soil types.
• Unadulterated Polyethylene Hose Construction: Manufactured from virgin polyethylene raw material without recycled content, ensuring maximum hose durability, flexibility in cold conditions, and resistance to UV degradation over extended service life.
• Variable Track Galvanized Raingun Trolley: Adjustable wheel spacing accommodates different crop row widths whilst galvanized construction protects against corrosion, maintaining smooth operation through seasons of exposure to water and field conditions.
• Comprehensive Monitoring Instrumentation: Equipped with tachometer for speed verification, glycerine-bath pressure gauge for accurate pressure monitoring under vibration, and speed equalizer for consistent retrieval rates, giving operators complete control over irrigation parameters.
• Heavy-Duty Wheel Configuration: Fitted with 11.5/80-15.3 12PR 6F agricultural tyres providing excellent traction and flotation on soft or wet soils, enabling relocation even during active irrigation seasons without field damage.
• Safety-Focused Design: Steel safety guards are swaged, galvanized, and painted for durability whilst protecting operators from moving components, alongside mechanical drawbar lifting to eliminate manual handling risks during transport operations.

Ideal Applications

• Large-Scale Arable Farming: Ideal for cereals, maize, soybean, and oilseed production on fields from 15 to 60 hectares, where the extensive hose length options enable complete field coverage with minimal relocations.
• Pasture and Forage Irrigation: Well-suited to grassland, alfalfa, and hay production where the REFLEX raingun with smaller nozzles delivers gentle precipitation rates that prevent soil compaction whilst maintaining productivity during dry periods.
• High-Value Vegetable Production: Supports potato, onion, carrot, and other vegetable crops requiring uniform water distribution, with nozzle selection enabling precise application rates matched to crop growth stages and soil infiltration capacity.
• Orchards and Permanent Crops: Effective for under-canopy irrigation in apple, pear, and nut orchards where variable speed control allows adjustment of application intensity to minimize canopy damage and match soil moisture requirements.
• Rental and Custom Application Services: The robust construction, low maintenance requirements, and comprehensive configuration range make the R4A an excellent choice for irrigation contractors serving diverse clients with varying field sizes and crop types.
• Water-Limited Agriculture: In regions with restricted water allocations or pressure limitations, the Turbo Speed system's ability to operate efficiently under low-pressure conditions maximizes irrigation effectiveness whilst conserving valuable water resources.
