Smart spending on smart machines - Financial tool to guide automation choices Autonomous machinery promises efficiency and labour savings, but for many growers, the real question is - will it actually pay off on my farm?
Advantages of autonomous machines Autonomous machines can oper- ate for longer hours, including overnight, helping growers com- plete critical tasks like sowing, spraying, and harvesting, within optimal windows. Alternate, smaller, lighter de- signs reduce soil compaction, improving soil health and crop performance over time. “By automating repetitive tasks, autonomous machinery can freeup skilled staff to focus on high-value management and agronomy de- cisions, while reducing reliance on seasonal labour,” says Dr Lawes. Precision operation ensures in- puts such as fertiliser, seed, and chemicals are applied more accur- ately, cutting waste and improving efficiency. “Together, these benefits allow farms to scale more effectively, experiment with new rotations or practices, and ultimately enhance the overall sustainability and prof- itability of the farming system.” Disadvantages of autonomous machines Although autonomous machinery
offers many benefits, there are also several potential disadvantages that growers need to consider. High upfront costs can be a significant barrier, especially for smaller or mixed enterprises, and ongoing maintenance, software updates, and repairs may add to the expense. Reliability can be a concern, par- ticularly during critical windows like seeding or harvest. Autono- mous machinery may require spe- cialist technicians to service them, and any downtime could lead to lost yield or missed opportunities. Some autonomous machines may struggle in challenging soils, wet conditions, or irregularly shaped paddocks, limiting their effectiveness. Dr Lawes explains that oper- ators and managers must first understand and then trust the technology to work seamlessly with it, while integration with ex- isting machinery or farm systems can require additional investment. “While autonomy reduces labour requirements, it doesn’t elimin- ate the need for human oversight. Farms may need to adapt work- flows and management practices to
Navigating the pros and cons of adopting automation for farm oper- ations can be a challenge. From interoperability, data management, and connectivity to organisational and social challenges, it can be com- plex and confusing. But the oppor- tunities for operational efficiencies are increasing. “Running a few financial invest- ment scenarios is key to making informed decisions about pur- chasing automated machinery,” says Dr Roger Lawes, Principal Research Scientist at CSIRO, Aus- tralia’s national science agency. Dr Lawes and his team at CSIRO are part of Grain Automate, a five- year, $35 million investment by Grains Research and Development Corporation (GRDC). The goal, by the end of the initiative in 2028, is to equip Australian grain growers with the knowledge, skills, data, infrastructure, and governance requirements to successfully in- tegrate autonomous field-based agricultural machines within their farming systems and businesses. “There is not a one-size-fits-all solution when it comes to adopt- ing autonomous machinery,” Dr Lawes says.
