Marani GT015B Turbine Drive Hard Hose Irrigator

Overview

The Marani GT015B is a turbine drive hard hose irrigator engineered and manufactured in Italy by Marani Irrigazione, a company with deep roots in professional irrigation technology. Designed for demanding agricultural environments, the GT015B combines a high-efficiency turbine drive system with a hot-galvanised chassis and reel, delivering reliable, consistent water distribution across a wide range of field configurations. Built around a flanged turbine and integrated gearbox, this machine is capable of handling hose diameters from 50 mm to 63 mm (1.97 in to 2.48 in) and hose lengths from 150 m to 230 m (492 ft to 755 ft), making it a versatile solution for medium to large-scale irrigation operations.

What sets the GT015B apart is its practical engineering philosophy — every component reflects a focus on low operating costs and straightforward maintenance. The turbine is flanged directly onto the gearbox with an external by-pass for precise flow regulation, while the automatic trolley lifting device and mechanical hold-down system ensure stable, repeatable field performance. The polyethylene hose is produced from unadulterated raw material for long service life, and the inclusion of a glycerine-bath pressure gauge allows accurate monitoring under working conditions. This is a machine built to the standard that working farmers expect from a quality Italian hard hose irrigator.

Key Features & Benefits

• Turbine Flanged on Gearbox with External By-Pass: Direct mounting of the turbine to the gearbox reduces mechanical losses and simplifies the drivetrain, while the external by-pass allows precise control of turbine speed and winding rate to suit varying field and pressure conditions.
• Automatic Trolley Lifting Device & Mechanical Hold-Down: The automatic lifting mechanism raises the raingun trolley at the end of the irrigation run, preventing ground damage and enabling smooth, consistent retrieval without manual intervention.
• Hot Galvanised Chassis, Turret, and Reel: Full hot-dip galvanisation of all primary structural components provides superior corrosion resistance in wet field environments, significantly extending the working life of the machine with minimal surface maintenance.
• Polyethylene Hose from Unadulterated Raw Material: The use of virgin polyethylene ensures the hose retains its flexibility, pressure rating, and UV resistance over many seasons, reducing the risk of premature cracking or deformation common with recycled-material alternatives.
• HYDRA Raingun with Interchangeable Nozzle Set: Each configuration ships with a set of HYDRA raingun nozzles ranging from Ø 12 to Ø 16 mm, allowing operators to tune the application rate and throw radius to match crop type, spacing, and available operating pressure.
• Galvanised Raingun Trolley on Variable Track Wheels: The adjustable track width on the raingun trolley accommodates different row spacings and field surfaces, ensuring stable travel and consistent throw geometry throughout the irrigation run.
• Glycerine-Bath Pressure Gauge: The glycerine-dampened gauge provides steady, readable pressure indication even under pulsing flow conditions, enabling operators to monitor system performance and detect supply issues without instrument vibration errors.
• Flexible Connection Pipe: The flexible hose connection between the main reel hose and the raingun trolley absorbs ground movement and angular misalignment during winding, protecting both the hose end fitting and the raingun inlet from fatigue stress.
• Heavy-Duty 20x10.0x8" Tyres (2PR 4F): The two large-profile agricultural tyres provide stable ground support across soft, uneven, or freshly tilled soils, reducing the risk of the machine sinking or tilting during operation.
• Winding Handle & Safety Guards: The manual winding handle allows hose tensioning and manual operation when required, while the fitted safety guards protect operators from rotating drivetrain components throughout the work cycle.

Ideal Applications

• Arable Crop Irrigation: Well suited to cereals, maize, and oilseed crops where long hose runs and wide throw rainguns allow efficient coverage of large open fields with minimal repositioning.
• Pasture and Forage Production: The variable nozzle set and adjustable application rate make the GT015B practical for grass and forage crops requiring regular, uniform water application throughout the growing season.
• Vegetable and Row Crop Fields: The variable track raingun trolley accommodates standard row spacings, and the controllable winding speed allows careful management of application depth on sensitive horticultural crops.
• Orchards and Permanent Plantings: Where wheel-move or lateral systems are impractical due to tree spacing or terrain, the hard hose irrigator provides a flexible, low-infrastructure alternative for supplemental irrigation.
• Fodder and Silage Crop Production: High-volume water delivery over medium to long runs supports the intensive growing cycles typical of silage maize and other high-water-demand fodder crops on farms without fixed irrigation infrastructure.
• Land Reclamation and Dust Suppression: The robust galvanised construction and high-flow capacity of the GT015B also make it suitable for non-standard applications such as compacted soil remediation watering or track and field dust control on agricultural properties.
