TAMA expects Fonterra's forecast for a lower dairy payout next year may reduce 2015 tractor sales by about 15 per cent from this year's highs. The 48 per cent slump in global dairy prices this year has led Fonterra to lower its forecast farmer payout to $5.30/kgMS and many analysts expect the dairy cooperative to further reduce the forecast when it comes up for review next month.
"We can't see it being any better, if anything, it might be a slightly more reduction," said TAMA's Massicks.
Still, he said the decline from a record could still underpin steady sales.
"Even at the level it is for next year, it is still a reasonable payout," he said. "There is no doubting this year's has been an absolute exceptional payout. It's still going to be a very healthy tractor market next year."
Tractor sales were probably even higher in the 1970s and 1980s, as volumes surged on the back of a change to farm mechanisation, he said.
