Local motorists are being urged to take care around agricultural vehicles as the region prepares for this year's grain and hay harvest.

NSW Farmers are warning motorists that large machinery will become a common sight on country roads over the coming months and the Grains Committee chair Justin Everitt said it is vital that caution is exercised when navigating around the machinery.

"Tractors, headers, augers and more will soon be on our roads as many farmers gear up to get their grain and hay out of the paddock and into market," Mr Everett said.

"Tailgating on unpredictable overtaking is particularly dangerous around these heavy vehicles, so be ready to look out, slow down and take care on the road, and farmers will make sure they can shift out of your way as soon as it's safe."

Mr Everett said he understands the machinery might be a little slow moving.

"The most important thing is that we all get home safely at the end of each day," he said.

Mr Everett is also asking farmers to consider how they could prepare to keep themselves and their workforce safe heading into the busy harvest season.

"Spring is already here and summer isn't far away, so it's an extremely busy time for growers, and the combination of long days, hot weather, fatigue and heavy machinery can increase the risks on farm," he said.

"Straightforward plans and processes around servicing machinery, managing traffic, inducting workers, preventing fatigue and preparing for emergencies can make all the difference in ensuring the 2025 harvest is safe, productive and successful."
