The latest “H-Select” nozzle control technology on the Hardi Rubicon selfpropelled sprayer is enabling a Victorian farming family to achieve precision application
The Sanford family has been farming their 5,260-hectare grain property on Victoria’s Mallee for four generations.
The latest addition to the operation is a new 9,000-litre Hardi Rubicon self-propelled sprayer with the latest “H-Select” nozzle control technology.
“We were looking to increase capacity from our 6,200-litre
Case Patriot,” Tim Sanford explains. “The Rubicon 9000 had the capacity, but we needed it to have droplet control too. H-Select was brand new when we started looking at the start of the year, but the more we learned the more it looked like the best solution for us.”
The Sanford’s property has a mixture of soils and terrain, including some “quite rough” areas, and there is currently a mix of canola, barley, wheat and lentils to spray.
So Tim Sanford uses H-Select’s flexible droplet control in a number of ways, including switching to a larger droplet when drift becomes an issue – along fence lines or if the wind comes up while he’s spraying.
“You don’t always know what droplet size you’ll need until you get to the paddock,” he says, “and things can change once you start spraying. Being able to optimise your droplet to the conditions means you can finish the job.”
The extra-large capacity of the Rubicon 9000 helps too, with fewer refill breaks and faster, computer-aided refilling when you do.
“Twenty seven kilometres per hour would be a fairly typical speed for us,” Sanford reports. “Even with refilling I’ve finished one of our 260-hectare paddocks in three hours. I was pretty happy with that.”
The Sanfords prefer to spray at reasonably high water rates and, with their previous sprayer, forward speed would be limited by the maximum flow rate.
“Now we can keep our speed up and H-Select just opens nozzles to provide the flow rate,” says Sandford. “And you know the droplet size stays right.”
Equally, when they need to slow down in difficult country, H-Select uses its nozzle matrix to reduce the rate – maintaining both application and droplet accuracy.
On that kind of land, the Hardi Paragon boom’s unique ride also comes into its own. “You can see it just balances better,” says Sandford. “If a front wheel drops, the boom just floats up there for a second and that stops it hitting the ground. The Rubicon rides over the land very well,” Tim Sanford says, “and H-Select gives us the precise control we need.”
