McDonald Murphy Machinery was recently engaged to provide a new Miller sprayer fitted with a particular spraying system for long-term customer, Ramu Agri Industries located at Gusap Downs, Morobe Province, Papua New Guinea.
The addition of this machine took their fleet of Nitro 7310s to a total of 3 sprayers with 1 x 4WS (4 Wheel Steer) units and 2 x 2WS (2 Wheel Steer) units.
Ramu Sugar farms around 8000 hectares of sugarcane in Papua New Guinea and have their own sugar mill on the plantation, with all of the sugar they produce being for domestic use only and not exported. They are also involved in cattle for beef as well as palm oil production.
The model purchased by Ramu Sugar was the Miller Nitro 7310 2WS (2 Wheel Steer). Specs for this model included:
This particular Miller sprayer was the 2WS. A 4WS option is available.
Standard features include hydraulic adjustable suspension height giving a crop clearance of 1.8m – 2m. The suspension system is "proactive", constantly adjusting all 4 corners to keep the machine/boom level at all times taking into consideration speed, steering angle, braking force and tank volume (weight). It has a turning circle of 5.5m (this reduces to 4.1m on the 4WS models).
The Sprayer was optioned with a hydraulic adjustable axle width of 3.22m – 4.24m (for different row widths) on 480/80R42 tyres. Ramu Sugar also optioned the machine with a mono boom of 22m (primary only). At the dealership we setup the boom for dual circuits, flat boom TeeJet nozzles at 250mm spacings and 11 folding dropper legs (for inter-row spraying) operating 5 sections.
To get it to the customer, the sprayer was shipped from Townsville wharf into the Port of Lae in PNG. With the aid of bolt on lifting hubs, the sprayer was able to be craned on and off the ship. Normally some of our technicians and/or myself as the Product Specialist, would travel to PNG for the delivery of machinery and to assist with the starting operations and training however, due to COVID this year, this was unfortunately not possible with the assistance having to be done remotely instead.
