Firefighters were called to Edgecombe Road Kyneton shortly after 6pm yesterday after callers to triple zero reported a large tractor had caught fire.
The tractor was fully engulfed in flames when CFA brigades from Kyneton and Malmsbury arrived on the scene.
High winds and thick acrid smoke hampered the efforts of firefighters who donned breathing equipment to attack the flames.
At the height of the fire, embers from the blaze were carried 100m along the road threatening nearby properties and paddocks.
Edgecombe Road was closed for about an hour while the wreckage was removed. It is believed a burst hydraulic line caused the fire.
The driver of the tractor was uninjured.
