The 66-year-old man was taken to hospital with serious head injuries, but died on Friday 1 July.
WorkSafe is investigating the incident.
The death brings the workplace fatality toll to 27 for 2022, six fewer than at the same time last year.
This comes after another man was declared deceased after being injured while using a harvester at a Ure Road farm in Gembrook on Wednesday 29 June.
