Product Overview

Summary: This Combine Harvester Repair Safe Operating Procedure sets out a clear, step-by-step method for safely inspecting, fault-finding and repairing combine harvesters in Australian agricultural operations. It focuses on controlling high-risk hazards such as entanglement, crush injuries and stored energy, while helping farms and contractors maintain reliability through the harvest season.

Combine harvesters are among the most complex and hazardous pieces of machinery used in Australian farming. Breakdowns during harvest are stressful, time-critical and often occur in dusty, hot and remote conditions, which can push workers to take shortcuts that significantly increase the risk of serious injury. This Combine Harvester Repair Safe Operating Procedure provides a structured, safety-first approach to fault diagnosis, isolation, repair and recommissioning of harvesters, both in the field and in the workshop. It embeds lock-out/tag-out practices, safe access methods and clear communication steps so that repairs can be completed efficiently without compromising worker safety.

The SOP is designed to help agricultural businesses demonstrate due diligence under WHS legislation by standardising how repairs are planned, authorised and carried out. It covers pre-repair risk assessment, machine shutdown and isolation, managing stored hydraulic and electrical energy, working around cutting and moving parts, as well as housekeeping and documentation after the repair. By implementing this procedure, farms and contractors can reduce unplanned downtime, minimise the risk of entanglement and crush injuries, and provide consistent training material for seasonal workers, apprentices and new team members. The result is a safer, more reliable harvest operation that aligns with Australian standards and best practice for agricultural plant.

Key Benefits

• Reduce the risk of entanglement, crush and amputation injuries during repair activities on combine harvesters.
• Ensure consistent application of lock-out/tag-out and isolation procedures across all repair tasks.
• Improve harvester reliability and minimise costly downtime during critical harvest windows.
• Standardise repair practices and training for permanent, casual and seasonal workers.
• Demonstrate compliance with Australian WHS duties for the safe maintenance of plant and equipment.
