Nitro 7310sp: The latest self-propelled sprayer from Miller

The Nitro 7310 is a new addition to the range that replaces the model 5225 and comes in 3785- and 4542-litre (1000- and 1200-gal) sizes with a mid-mounted tank, a rear-mounted engine and front-mounted booms up to 41m (135ft) wide.

The header rail strip highlights the sections operating, as well as functions such as liquid recirculation, pumping, 4-wheel steer and auto steering.

Display screen features

Alongside, a display screen positioned above the right-hand cab pillar shows key digital vehicle instruments such as ground and engine speed, with the items displayed selected through a touch screen console mounted on an adjustable arm attached to the seat.

Above this, on a separate arm, Miller provides the Raven Viper 4+ field computer, which is used to set-up, adjust, monitor and record spraying operations via its 12.1in tablet-style touch screen display.

Operators can use it portrait or landscape and customise the display, and save it as a profile for different applications or different operators.

Inside the all-new cab there are 3 screen displays to the front right of the driver and a ‘spray on/off’ strip display in the headliner to the left of the audio unit.

Built-in GNSS receiver

The Viper 4+ has a built-in GNSS receiver, acts as an isobus virtual terminal and can be used with Raven Slingshot, a precision agriculture system offering high-speed connectivity via cell technology, Cloud-based data transfer and management, data security and wireless RTK corrections.

Adjustable crop clearance

The Nitro 7310 itself has a new chassis providing adjustable crop clearance up to 1.98m (78in), as well as 4-wheel hydrostatic drive and steering.

No pre-mixing and spot spraying target weeds

For spraying, a new chemical injection system is available with up to 3 pumps and 4 containers to apply pesticide combinations without pre-mixing and to spot-spray specific target weeds beyond the scope of the mix.

Improved stability and visibility

A liquid fertiliser placement toolbar is available for the front-mounted boom arms, which are spaced wider than previously to improve stability and forward visibility.

The smaller display, mounted on an adjustable arm, provides vehicle set-up and instrument display access; a multi-function joystick for the hydrostatic drive is located on the seat-mounted console.

Instead of Cummins, power now comes from a 6.7-litre FPT engine with up to 310hp in North American trim, 288hp in Tier 2 emissions format for Australia and 282hp as a Tier 3 engine for South America where the machine is labelled Nitro 7285.

It’s the first new Miller sprayer since the company was acquired by CNH Industrial and in the United States it is also distributed by selected Case IH dealers and as the Guardian SP310F in New Holland colours.

Prices start at around $ 450,000 in the United States.
