Australia's biggest wheat farmer, Ron Greentree, has put Muttama Station, a 12,500 hectare cropping and grazing property west of Coonamble in the NSW Western Plains, up for sale after acquiring full ownership of it from former business partner Ken Harris in December.

The pair owned Muttama Station as part of their Greentree Farming partnership. They put it up for sale in November 2017 as part of plans to dissolve their business partnership and split up the remaining assets.
