VICTORIANS are being urged to avoid driving vehicles, farm machinery, mowers and motorbikes through dry grass in the coming weeks, as conditions continue to heat up and vegetation dries out.

Fuel areas in the north and south west of the state have cured significantly following the state's recent heatwave, resulting in CFA crews responding to a number of significant grass and stubble fires started by mowers, vehicles or machinery in the past fortnight.

CFA chief officer Jason Heffernan said recent fires across the state served as timely reminder for people to be aware of the fire risks associated with using vehicles and other machinery in and around dry grass.

"Victoria is expected to experience a grassfire–dominated fire season once again but we're asking the community to do all it can to prevent these fires from starting," he said.

"In many areas across the state, the risk of starting a fire from a hot exhaust system or other hot parts from farm machinery is high.

"Even pulling over into tall, dry grass on the side of the road during your travels could start a significant grassfire.

"Awareness is key to preventing grass and crop fires – we also want farmers to ensure their machinery and equipment are regularly inspected, maintained and cleaned."

According to Mr Heffernan, agricultural activities such as harvesting, grinding, welding, slashing or mowing could quickly ignite fires in hot, dry and windy conditions, and noted grassfires could move at speeds of up to 25kph and spread across roads and highways in the right conditions.
