The Sanford family invested in a 9000 litre HARDI RUBICON Self Propelled Sprayer, opting for the H-SELECT nozzle control technology.

The Sanford family have been farming their 5260-hectare grain property on Victoria's Mallee for four generations.

Last season, the family invested in a new 9000 litre HARDI RUBICON Self Propelled Sprayer, and opted for the sophisticated H-SELECT nozzle control technology.

"We were looking to increase capacity from our 6200 litre Case Patriot," Tim Sanford said.

"The RUBICON 9000 certainly had the capacity, but we needed it to have droplet control too."

The Sanford's property has a mixture of soils and terrain, including some "quite rough" areas, and most seasons they grow a mix of canola, barley, wheat and lentils.

H-SELECT had only just been introduced when the Sanfords started looking into it at the beginning of 2018, but the more they learned about, the more convinced they became that it was the best solution for their property.

Since installing their big new sprayer in spring, Tim has used H-SELECT's flexible droplet control in a number of ways, taking advantage the in-cab run screen to select larger droplets for reducing the chance of drift along fence lines, or if the wind increases during spraying.

"You don't always know what droplet size you'll need until you get to the paddock and things will often change after you've started spraying," he said.

"Being able to keep adjusting our droplet size to the conditions means I can be much more certain of getting the job finished."

The extra large capacity of the RUBICON 9000 helps there too, with fewer refill breaks and faster, computer-aided refilling. 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.

"With H-SELECT we can keep the speed up, and the system will automatically open extra nozzles to maintain the desired flow rate," he said.

"And the droplet size stays exactly right the whole time. 27 km/h is a fairly typical spraying speed in the RUBICON. So even with refilling breaks, I've been able to finish one of our 260 hectare paddocks in about three hours. I've been pretty happy with that."
