Acremaster farm tractors were bold, rugged, and built to endure the demanding conditions of Australian agriculture. Designed and manufactured in Merredin, Western Australia, Acremaster specialized in large, articulated four-wheel-drive tractors during the 1970s and 1980s.
Founded by Laurie Phillips, Acremaster quickly earned a reputation for building durable and powerful machines ideal for broad-acre farming. These tractors were not mass-produced but crafted with precision and scale in mind—designed to handle vast fields and harsh terrain. Acremaster Farm Tractors.
Partnership with International Harvester Australia
A turning point in Acremaster’s history came when the company briefly partnered with International Harvester (IH) Australia. For two years leading up to IH’s acquisition by Case Corporation, Acremaster produced tractors under contract for IH, adding international recognition to its local success.
In 1985, the company was acquired by Horwood Bagshaw, another iconic Australian agricultural equipment maker. Production continued on a custom-order basis until 1987, after which Acremaster ceased manufacturing tractors.
