Marani GT026B Turbine Drive Hard Hose Irrigator

Overview

The Marani GT026B is a turbine drive hard hose irrigator engineered and manufactured in Italy by Marani Irrigazione, a brand long recognised for producing robust, field-ready irrigation machinery with an exceptional balance between operational performance and long-term cost efficiency. Designed to deliver reliable, large-scale field irrigation, the GT026B operates on a water-turbine drive system and is built to handle hose diameters ranging from 70 mm to 100 mm (2.76 in to 3.94 in) and hose lengths from 170 m to 350 m (558 ft to 1,148 ft), making it suitable for a wide variety of agricultural landscapes and crop types.

What sets the GT026B apart within the Marani lineup is its combination of a 3-speed gearbox with turbine-driven winding, a hot-galvanized chassis and reel for long-term corrosion resistance, and compatibility with both the ROYAL and REFLEX raingun families — allowing the machine to be precisely configured to match the irrigator's pressure, flow, and coverage requirements. The inclusion of a speed equalizer ensures consistent winding speed throughout the full length of the hose, delivering uniform water application across the entire irrigated strip. With a polyethylene hose manufactured from unadulterated raw materials, galvanized double water inlet, and mechanically adjustable feet and lifting device, the GT026B is built to perform season after season with minimal downtime.

Key Features & Benefits

3-Speed Gearbox: Provides flexibility to adjust hose retrieval speed to suit varying soil types, crop sensitivities, and application rate requirements, giving the operator precise control over irrigation uniformity.
Turbine Flanged on the Gearbox with Built-In By-Pass: The integrated turbine and by-pass design ensures smooth, water-powered operation while allowing the operator to regulate drive speed without interrupting water flow to the raingun.
Speed Equalizer: Automatically compensates for the changing diameter of the hose reel as the hose winds in, maintaining a consistent linear travel speed and ensuring uniform water distribution from the first metre to the last.
Hot-Galvanized Chassis, Turret, and Reel: Full hot-dip galvanization of all structural components provides superior resistance to rust and corrosion, extending the working life of the machine even in harsh environmental conditions.
Mechanical Lifting Device and Telescopic Mechanical Feet: Simplifies hitching and unhitching in the field and allows for quick, stable levelling on uneven ground, reducing setup time and improving safety during operation.
Galvanized Raingun Trolley on Variable Track Wheels: The adjustable-track trolley accommodates different field conditions and row spacings, while the galvanized construction ensures the trolley withstands continuous outdoor exposure.
ROYAL and REFLEX Raingun Compatibility with Multiple Nozzle Sets: The machine ships with a full set of ROYAL nozzles (Ø 16 to Ø 22) and REFLEX nozzles (Ø 24 to Ø 32), enabling the operator to fine-tune coverage diameter and precipitation rate across a wide range of operating pressures and flow rates.
Polyethylene Hose from Unadulterated Raw Material: The use of virgin-grade polyethylene ensures consistent hose wall integrity, flexibility, and pressure resistance, reducing the risk of premature hose failure or performance degradation over time.
Galvanized Double Water Inlet: The dual-inlet configuration allows greater flexibility in field positioning relative to the water supply, while galvanized construction ensures long-term seal integrity and corrosion resistance.
Glycerine Bath Pressure Gauge and Safety Guards: The glycerine-filled pressure gauge delivers stable, vibration-dampened readings for accurate monitoring, while the swaged, galvanized, and painted steel safety guards protect both the operator and mechanical components during operation.

Ideal Applications

Arable and Row Crop Irrigation: The GT026B's long hose reach — up to 350 m (1,148 ft) — and wide nozzle selection make it well suited to irrigating large, open fields of cereals, maize, sunflower, and other broadacre crops where maximising coverage per setup is essential.
Forage and Pasture Management: The machine's variable winding speed and uniform application rate support consistent soil moisture levels across extensive pasture areas, promoting even grass growth and reducing localised dry patches.
Vegetable and Horticultural Production: With the ability to select smaller ROYAL nozzles for lower application rates, the GT026B can be configured for vegetable crops and market gardens where precise water placement and avoiding soil compaction are priorities.
Soil Preparation and Pre-Irrigation: The high-flow REFLEX raingun configurations with 90 mm and 100 mm hose diameters (3.54–3.94 in) allow rapid field wetting ahead of planting or cultivation operations, even across large field areas.
Mixed Farming Operations: The broad range of available hose diameter and length combinations means a single GT026B unit can serve multiple field types and crops across a diversified farm, reducing the need for multiple dedicated machines.
Fields with Irregular Terrain: The telescopic mechanical feet, variable track raingun trolley, and robust galvanized chassis allow the GT026B to operate reliably on sloping, uneven, or difficult terrain where lesser machines may struggle to maintain stability and performance.
