Adding a Gregoire Besson ‘Discordon One-Pass Finisher’ to their fleet has transformed Harriss Contracting’s clay spreading and soil improvement services across southern WA, delivering more efficient incorporation, alleviating compaction, and helping to tackle non-wetting soils.
Run by Ben and Kate Harriss, the Narrikup-based contracting business services farms from the Lower Great Southern to the south-eastern wheatbelt. With the new machine, growers benefit from a complete end-to-end clay spreading and incorporation service, saving time and improving results in a single pass.
