10 years of autonomous ups and downs on a 16,000 hectares Australian farm

For over a decade, Beefwood Farms, located north of Moree in New South Wales, Australia, has been at the forefront of agricultural innovation, investing in autonomous and unmanned machinery to revolutionize farming practices. Owner Gerrit Kurstjens has been a staunch advocate for this technology since 2015, envisioning a future where precision agriculture and automation transform the industry. However, the journey has not been without its challenges, as Kurstjens navigates a complex landscape of acquisitions, manufacturers, and even counteractions.

In 2023, Beefwood Farms participated in a demonstration of SwarmFarm Robotics' SwarmBot, hoping to integrate it into their operations. Unfortunately, the robot was not yet ready for the farm's needs. The SwarmBot's inability to operate autonomously at night and its limited working width of 18 meters, combined with a slow operating speed, left much to be desired. Kurstjens recalls, "We were eager to adopt the technology, but the SwarmBot simply didn't meet our requirements at the time."

After an extensive search for a suitable alternative, Beefwood Farms settled on the tracked AgXeed 5.115T2 AgBot. Kurstjens highlights the diesel-electric drive as a significant advantage, as it offers a reliable power source for the farm's operations. The AgBot is capable of pulling an 8,000-liter, 48-meter spot sprayer, which is crucial for the farm's daily operations. Kurstjens explains, "We spray 1,000 hectares per day, and the AgBot's capabilities are essential to keep up with this pace."

Initially, the farm began with a 24-meter wide spot sprayer equipped with WEED-IT sensors. However, Kurstjens wanted to upgrade to a 48-meter spot sprayer to increase efficiency. The wider boom presented challenges, particularly during turns on headlands. The LiDAR sensor on the AgBot identified the spray booms as obstacles, causing the vehicle to stop. Accommodating the 48-meter spray rig behind the AgBot would require significant modifications to both the vehicle and the spray rig. This would mean that the AgBot would no longer be a standard machine, which was not desirable.

Moreover, the farm is accustomed to spot spraying at speeds of 15 to 16 km/h, while the AgBot's maximum operating speed is 10 km/h. Despite these limitations, Kurstjens acknowledges that the AgXeed 5.115T2 AgBot pulling a 24-meter wide Croplands spot sprayer equipped with WEED-IT sensors has proven to be a valuable asset for the farm.

Throughout the years, Beefwood Farms has faced numerous obstacles in adopting autonomous technology. The challenges range from manufacturers not fully understanding the specific needs of the farm to the technical limitations of the equipment. However, Kurstjens remains optimistic about the potential of autonomous machinery to transform agriculture.

Despite the setbacks, Kurstjens' vision for a future with advanced farming technology remains unwavering. The farm's commitment to innovation and its dedication to finding solutions to overcome obstacles demonstrate a pioneering spirit that is driving the agricultural industry forward. As Beefwood Farms continues to explore new possibilities with autonomous machinery, it serves as an inspiration for other farms around the world, striving to maximize efficiency and productivity while adapting to the ever-changing landscape of modern agriculture.
