Federated Farmers is urging all rural folk to take precautions to try to ensure work activities don't spark a vegetation blaze.
One risk that may be overlooked is clumps of cowpat or similar material sticking to the exhausts of quad bikes and other vehicles, Feds Hawke's Bay President Jim Galloway said.
"It sticks on there, dries, heats and starts smoldering. If that falls into dry grass it can set off flames."
The region has already experienced rural fires, including at Tikokino, Clarkson's Hill and off Moteo Pa Rd.
"It's thought two of the fires were caused by the blades of a mower striking stone, wire or something else hard and causing a spark. In the current conditions, farmers and others should think very carefully about whether it's safe to do mowing or topping or any other activity that could cause sparks" said Galloway.
