The full Sunrise Ag dealerships in Swan Hill and Ouyen and the Case IH broadacre component of the Mildura outlet have been purchased by O'Connors, taking the company from 12 to 15 locations.

The deal is expected to be finalised in early May.

O'Connors chief executive officer, Gareth Webb, said the Sunrise Ag dealerships were a good fit for the business and the expansion helped reinforce the strength of the O'Connors network.

"The Sunrise Ag location at Ouyen represents a strong broadacre farming area where we have considerable knowledge and experience, while Mildura and Swan Hill have more agricultural diversity where we can work to expand the reach of Case IH smaller horsepower machinery," Webb said.

"That diversity is exciting for us and we see a lot of opportunities across the three locations. We have 58 years of experience in the agricultural machinery industry, representing the Case IH brand, and building a reputation for outstanding service, and second-to-none knowledge of the industry and commitment to our customers."

This most recent expansion extends O'Connors' footprint from Ballarat in southern Victoria, north to Condobolin in the New South Wales, and east to Corowa, New South Wales and Shepparton in Victoria, linking up the dealership network. It follows last year's acquisition of former Agrimac dealerships in Ballarat and St Arnaud in Victoria.

"We look forward to working with Case IH customers in these new regions and helping deliver what they need to keep their businesses as profitable and efficient as possible," Webb said.
