Marani GT070B Turbine Drive Hard Hose Irrigator

Overview

The Marani GT070B is a heavy-duty turbine drive hard hose irrigator engineered and manufactured in Italy by Marani Irrigazione, a brand with a long-standing reputation for precision-built irrigation machinery. Designed to deliver high-volume water application across large agricultural fields, the GT070B is built around a hydraulic turbine drive system that harnesses water pressure to power the reel winding mechanism — eliminating the need for external fuel or electrical connections during operation. With hose diameter options ranging from 100 mm to 140 mm (3.94 in to 5.51 in) and hose lengths up to 600 m (1,969 ft), this machine is engineered for serious large-scale field irrigation on arable farms, horticultural operations, and agricultural estates.

What sets the GT070B apart is its combination of Italian engineering quality, robust galvanised construction, and a thoughtfully selected standard equipment package that balances operational performance with long-term cost efficiency. The 4-speed gearbox offers genuine flexibility in winding speed and application rate, while the built-in turbine bypass, speed equaliser, and tachometer give the operator precise control over uniformity of water distribution. Available in twelve distinct hose configurations paired with either REFLEX or EXPLORER rainguns, the GT070B is a versatile hard hose irrigator capable of handling demanding irrigation schedules across a wide range of field sizes and crop types.

Key Features & Benefits

4-Speed Gearbox: Provides four selectable winding speeds, allowing operators to fine-tune the travel speed of the raingun trolley and achieve the desired application depth for different soil types and crops.
Turbine Flanged on Gearbox with Built-In Bypass: The direct-flanged turbine-to-gearbox connection minimises mechanical losses and improves transmission efficiency, while the integrated bypass ensures smooth pressure regulation throughout the irrigation cycle.
Hot Galvanised Chassis, Turret, and Reel: All primary structural components are hot-dip galvanised for maximum corrosion resistance, extending the service life of the machine even in wet and chemically aggressive agricultural environments.
Hydraulic Lifting Device and Telescopic Hydraulic Feet: Simplifies field positioning and coupling by allowing the operator to raise and level the machine hydraulically, reducing manual effort and setup time on uneven terrain.
Speed Equaliser and Tachometer: The speed equaliser compensates for pressure fluctuations during operation, maintaining consistent trolley travel speed. The tachometer provides real-time feedback so the operator can monitor and confirm correct winding speed at all times.
Polyethylene Hose from Unadulterated Raw Material: The lay-flat or coiled PE hose is produced from pure, unblended polyethylene, ensuring consistent wall thickness, high burst pressure tolerance, and long service life without premature cracking or deformation.
Galvanised Raingun Trolley on Variable Track Wheels: The adjustable track width of the raingun trolley allows it to travel between different row spacings and field layouts, improving versatility across mixed farming operations.
Galvanised Double Water Inlet: The dual inlet design facilitates convenient connection from either side of the machine, improving flexibility when positioning the irrigator relative to the water supply point in the field.
Safety Guards Made of Steel, Swaged, Galvanised, and Painted: Heavy-duty safety guarding protects operators from moving mechanical parts and meets required safety standards, whilst the swaged and galvanised finish ensures the guards themselves resist corrosion and physical damage.
Pressure Gauge (Glycerine Bath): The glycerine-dampened pressure gauge provides a stable, easy-to-read pressure reading even under the vibration and pulsation typical of turbine-driven irrigation systems, supporting accurate machine setup and monitoring.
