Ocmis R4/1AR Turbine Drive Hard Hose Irrigator

Overview

The Ocmis R4/1AR is a professional hard hose reel travelling irrigator manufactured by Ocmis Irrigazione, Italy's premier irrigation equipment specialist. This robust machine represents one of the best-selling models in the Ocmis range, combining high-performance irrigation capabilities with exceptional versatility across multiple hose configurations. Designed for demanding agricultural operations, the R4/1AR features a sophisticated 4-speed gearbox system and advanced turbine technology that delivers reliable performance even under challenging conditions with low inlet pressures and flow rates.

What distinguishes the R4/1AR from conventional hose reel irrigators is the integrated Turbo Speed system, an innovative technology that dramatically reduces turbine load loss whilst providing access to a comprehensive range of machine speeds across varied operating conditions. The machine comes equipped with telescopic hydraulic feet for superior field stability, a hot galvanised chassis for exceptional corrosion resistance, and comprehensive standard equipment including both REFLEX and EXPLORER raingun options with interchangeable nozzle sets. With hose configurations ranging from 90 mm to 125 mm diameter and lengths extending up to 570 metres, the R4/1AR delivers the flexibility required for diverse field sizes and irrigation requirements whilst maintaining the low running and maintenance costs that have made it a trusted choice for agriculturalists worldwide.

Key Features & Benefits

• Turbo Speed System: Innovative turbine technology reduces load loss and enables optimal machine speed selection even with low flow rates and inlet pressures, maximising operational efficiency across varying field conditions.
• 4-Speed Gearbox with Power Take-Off: Multiple speed options provide precise control over irrigation rates and travel speed, allowing operators to match machine performance exactly to crop requirements and field topography.
• Telescopic Hydraulic Feet with Pump: Trolley lifting system and adjustable hydraulic stabilisers ensure rock-solid positioning on uneven terrain whilst simplifying transport between irrigation sites.
• Hot Galvanised Chassis and Turret: Superior corrosion protection through comprehensive galvanisation treatment extends machine lifespan significantly, particularly in humid climates or when using chemigation applications.
• Dual Raingun Options: Factory-equipped with interchangeable REFLEX and EXPLORER rainguns plus comprehensive nozzle sets (Ø24-32 mm for REFLEX, Ø28-40 mm for EXPLORER), providing exceptional application flexibility for different crops and weather conditions.
• Premium Polyethylene Hose Construction: Manufactured from unadulterated raw materials, the hose delivers excellent durability and flexibility whilst resisting degradation from UV exposure and chemical treatments.
• Galvanised Variable Track Raingun Trolley: Adjustable wheel spacing accommodates different row widths whilst galvanised construction ensures long-term reliability in field conditions.
• Comprehensive Instrumentation: Standard tachometer and glycerine-bath pressure gauge provide real-time monitoring of critical operating parameters, enabling operators to maintain optimal irrigation performance and detect issues immediately.
• Speed Equaliser Technology: Maintains consistent travel speed throughout the irrigation cycle regardless of hose tension variations, ensuring uniform water application across the entire field length.
• Heavy-Duty Wheels: Robust 11.5/80-15.3 12PR 6F wheels provide excellent traction and flotation across soft or uneven ground whilst minimising soil compaction damage.

Ideal Applications

• Large-Scale Field Crops: Optimised for irrigating extensive acreages of cereals, maize, soya, and fodder crops where long hose lengths and consistent water distribution are essential for uniform yields.
• Vegetable Production: Variable track raingun trolley and precise speed control enable effective irrigation of row crops including potatoes, onions, carrots, and brassicas whilst minimising crop damage during operation.
• Pasture and Forage Management: Excellent choice for maintaining productive grasslands and establishing fodder crops, with lower nozzle options providing gentle application rates suitable for newly seeded areas.
• Orchards and Vineyards: Adjustable speed settings and comprehensive nozzle selection allow tailored irrigation programmes for permanent crops with varying water requirements throughout the growing season.
• Chemigation Applications: Galvanised construction and chemical-resistant polyethylene hose enable reliable fertigation and pesticide application, whilst precise speed control ensures accurate chemical distribution rates.
• Undulating Terrain: Hydraulic stabilisation system and robust chassis design provide reliable operation on sloping or uneven fields where conventional irrigators struggle to maintain consistent performance.
