THE CFA is urging residents living in rural areas to register their burn-offs.
And due to heavy winter rains, which has seen increased growth, farmers looking to slash their crops need to take extra care when using electrical equipment.
The warnings comes as the CFA revealed it responds to more than 200 harvesting related fires every year.
CFA Chief Officer Steve Warrington said machinery fires can be avoided if farmers follow the correct practices.
"The key to avoiding harvester fires is diligence; farmers need to make sure they are thoroughly cleaning their machinery and inspecting it before use," Mr Warrington said.
"Hot and dry days are a particular concern for CFA, - if it's a high fire-risk day, our advice is to postpone work you are planning on doing in the paddock.
"During hot weather harvesting, grinding, welding, slashing or mowing can spark fires quite easily."
Chief Officer Warrington warned about driving vehicles and motorbikes through dry grass.
"The risk is that your car can heat up and ignite the dry grass underneath on those really hot days. This is incredibly dangerous and last season we saw cars and machinery sparking quite a few fires," he said.
Fire restrictions are already in place in far east Gipplsand with the rest of Victoria expected to follow within weeks.
Locally, it is encouraged that all burn offs should be completed by Ballarat Cup Day on November 23.
"We encourage residents to take advantage of the window of opportunity to clean up their properties before the bushfire season, but we're also reminding people to always register their burn-offs so we know what is happening in the area, especially if brigades are being called to fires," Mr Warrington said.
"It reduces the chances of CFA brigades being called out unnecessarily if a member of the public calls about smoke or a fire in the area.
"The effects of an out-of-control fire can be devastating. Even if you have registered your burn, conditions can change quickly and fires can get out of control within minutes in hot and windy conditions."
He added that people should never leave a burn-off unattended as it's the resident's responsibility to ensure that it does not get out of control.
"If a burn-off does get out of control, call '000' immediately. People should have a fire plan and prepare for the event of fire, and never be complacent," he said.
