It all started with hairy berries!

Although it sounds unlikely, the birth of Trimax Mowing Systems had a lot to do with brown furry fruit. Modern kiwifruit production was pioneered in New Zealand in the 1970's and the Bay of Plenty region, where Trimax began, was the centre of activity. The area underwent a complete transformation in a decade. Large areas of cow pasture became kiwifruit orchards almost overnight and numerous businesses, big and small, competed to service the new industry. Among them were many small engineering enterprises that manufactured tractor-mounted mowers to cut the grass beneath the kiwifruit vines. Three of these businesses eventually combined to become Trimax Mowing Systems.

Meanwhile, another business in Wellington made sliding hooks for meat processing plants. Part owner Bob Sievwright had trained in engineering with General Motors in New Zealand and at the General Motors University in Flint, Michigan. Mower manufacturers needed blades for their machines and Bob's company was happy to supply anything they asked for. But Bob had a better idea and produced a new type of flail for mower/shredders. Looking for more challenges, he decided to buy one of the leading mower makers and build a better machine.

The deal was all but through when his plans went up in smoke. Fire destroyed the plant! Undeterred, Bob secured the manufacturing rights and bought another mower-making shop so he could carry on. The new mower/shredders fitted with his revolutionary Gamma™ Flail blades were an outstanding success. Trimax mowers were born.

Jim McEwen was the owner of the third small engineering enterprise. He had developed a range of advanced low-profile, multi-spindled rotary mowers called Procut. When Bob wanted to add rotary mowers to his range of flail mower/shredders, he purchased the Procut company. In doing so, he bought more than a rotary mower range. He also secured Jim's services. Jim's unique talent for blending style into functional mechanical devices heralded a new era for Trimax.

from kiwifruit to turf

Although kiwifruit production was the launching pad for Trimax, the pace of kiwifruit growth could not continue forever. Trimax adapted its machines for parks and reserves mowing and began exporting in 1985. Since then, rapid product development has followed, resulting in the range of Trimax mowers you see today.

Since its inception Trimax has come a long way. Its journey may have started with brown furry fruit in New Zealand, but the Trimax team's passion has taken them around the globe. No longer just specialist kiwifruit orchard machines, Trimax mowers now groom highly manicured sports grounds and turf farms, safety-conscious schools, demanding golf courses, rough roadsides and beautiful city parks around the world.

Automation and robotic and technology are increasingly used in the manufacturing process to ensure consistently high quality levels. Continuous process improvement and innovation in mower design and production will keep Trimax on the 'cutting edge' of mower technology.

In addition to the manufacturing facility and head office, Trimax has branches in Australia (servicing Australia, the Pacific and South East Asia), the UK (servicing the UK, Scandinavia, and Europe) and USA (servicing the USA, Canada and South America), allowing them to provide 'Trimax' service levels to these continents.
