It's been a wet start to the 50th Henty Machinery Field Days in the states south west.

You won't hear farmers complain though, they've hanging out for the rain to finish off winter crops.

National Farmers Federation President Duncan Fraser says the decent downpour this week will give grain crops a lift and boost confidence in the farming sector as paddocks start to dry off.

"I know the weather bureau was saying we could expect above average rainfall for southern NSW and Victoria for spring but we were starting to doubt that.

"So to get that it in by Henty Field Days time is ideal for croppers especially, but also for summer croppers, it also gives them more bast given the restrictions on water allocations for irrigated summer crops."

So in a season like this one, are farmers prepared to fork out big money for new gear like headers and tractors ?

Adrian Quilty from GJW Harvest, a machinery dealer from Wagga Wagga, says the recent rain has made big difference to the market.

"I think a good inch of rain in Wagga and in other areas that had up to 40 millimetres, that stuff makes blokes really confident.

"So they have no fears going into this harvest and buying machinery doesn't scare them as what it would in a dry year."
