A fire which burned five hectares at Bletchley, east of Strathalbyn, is believed to have been started by a tractor.
Country Fire Service (CFS) was called to the fire at Burnlea Road near Hudd Road just after 12pm on Thursday, February 8.
A CFS spokesman said six fire trucks and four water bombers attended the fire which burned through grassland and paddocks.
He said there were two separate fires in the small area. The fires burned in a northerly direction.
A warning was issued to people in the area that the fire could threaten their safety, but another message was sent out an hour later to inform that the threat had reduced.
Following swift action, firefighters contained the blaze about 3pm.
People in the area are urged to take care on the roads as there may be smoke and falling branches.
Nearby property owners should check for any fires and embers in roof spaces, under decks and raised floors, and in gutters.
