Farmers' Mutual Group has launched a campaign to highlight the greater risk of tractor fires during the bird-nesting season from September to November.
The rural insurer urges farmers to take the time to check under their tractor bonnets for nests, saying it receives about 70 claims a year - worth about $1.2 million in total - for damage caused in tractor fires.
FMG marketing manager Glenn Croasdale says a simple check can ensure farmers don't lose an important piece of machinery during a busy time of year.
He says farmers can also help by leaving the bonnets of their tractors up when the vehicle is not in use to prevent birds nesting in the engine in the first place.
The FMG campaign includes a short video on YouTube and a leaflet drop to the 12,000 customers who have 20,000 tractors insured with the company.
