Farm Pro
USA • 14 Models
Farm Pro was a tractor brand that operated from approximately 2003 to 2012, primarily in the United States. The brand was created by Homier Distributing of Indiana, a company that specialized in marketing affordable agricultural equipment to small-scale farmers and rural communities. Farm Pro tractors were not independently manufactured but rather re-badged versions of tractors produced by Jinma, a Chinese agricultural machinery manufacturer. This strategic partnership allowed Homier to offer cost-effective tractors that catered to the needs of small and medium-sized farms, providing an accessible option for agricultural operations with budget constraints. The Farm Pro brand gained recognition for its straightforward, no-frills approach to tractor design, focusing on durability and practicality rather than advanced technological features. During its operational years, Farm Pro tractors were commonly found on small family farms, hobby farms, and in niche agricultural sectors where low-cost, reliable machinery was essential. The brand's discontinuation in 2012 marked the end of Homier's venture into the tractor market, but it left a legacy of affordability and accessibility in the agricultural equipment sector.
