About Acremaster
Acremaster was an Australian builder of large articulated four-wheel-drive tractors founded by Laurie Phillips in Merredin, Western Australia. Its original production story spans the 1970s and 1980s.
- Beginning
- First tractors reported in 1975
- Founder / origin
- Laurie Phillips, Merredin, Western Australia
- Known for
- Large articulated four-wheel-drive tractors
- Sale / later history
- Horwood Bagshaw bought the business in 1985; original custom-order production lasted until 1987
Built for Australian farming
Acremaster’s early machines were developed in Western Australia. The original 400-series included the high-powered 404A, and the business also built tractors for International Harvester Australia for a short period.
Ownership and the original production run
After ownership changes, Horwood Bagshaw acquired Acremaster in 1985 and offered custom-order machines until 1987. That date describes the original production run; it should not be read as proof that every later use or proposed revival of the Acremaster name ended then.

Index power values can include estimates derived from belt or PTO power. They are identified on each model card and are not interchangeable with a measured engine rating. Model years and missing values follow the source index.
