Leith Engineering was built on practical problem-solving and a deep connection to Australian agriculture, growing from early trailer manufacturing into a trusted name in farm machinery. From innovative beginnings to a diverse, nationwide product range, every piece of equipment reflects decades of experience and a commitment to durable, Australian-made performance.
Humble beginnings
Leith Engineering was officially registered as a manufacturer of agricultural machinery and provider of general repairs in 1980. However, the foundations of the business were laid decades earlier.
Wally Leith began building and selling side trailers in 1960, followed by the introduction of the “drop spreader” in 1963. This innovative machine was designed and manufactured to enable the fast and efficient application of gypsum as a soil improver, addressing the practical needs of Australian farmers.
By the mid-1970s, the business had expanded significantly, employing local staff and increasing its manufacturing capacity. As demand grew, so did the product range. The original drop spreader was redeveloped into a trailing model, produced in multiple sizes and available with either hydraulic or power take-off (PTO) drive systems. Alongside this growth, Leith Engineering also manufactured custom items to meet specific client requirements and established a dedicated farm machinery maintenance and repair service.
Our commitment
Over the past 60+ years, Leith Engineering has continued to evolve. Our range of comb trailers has become a cornerstone of the business, with designs continually reviewed and refined to meet the changing needs of Australian farmers and contractors. Today, our comb trailers, grain conveyors, gypsum spreaders and rotary mowers are sold nationwide.
At Leith Engineering, we remain committed to building high-quality, Australian-made equipment tailored to individual customer requirements. We take great pride in every product that leaves our factory bearing the Leith name — a name that has stood for durability, reliability and innovation for more than six decades.
