Trimax From The Start

Trimax From The Start

Trimax founder, Bob Sievwright, talks to us about how far he’s brought the company from its origins in the 1980s, flail mowing the grass under kiwifruit vines in the Bay of Plenty. Now with offices in the UK, US, Australia and New Zealand as well as distributors across Europe, Trimax has built an unparalleled reputation among turf maintenance professionals for cut quality and machine durability.

The Tractor Whisperer
“I’m a farmer’s son,” says Sievwright. “I grew up on a small back country cattle and sheep farm where the main challenge was converting rough scrubland into decent pasture for the animals. My siblings, my twin brother and I worked every hour available after school, weekends and holidays. Most of the pulling on the steep hills was done using horses, but it turned out I was useless on a horse; I kept falling off. So, from the age of about 12, I gravitated towards the tractor and farm machinery. The horses knew they were smarter than me but the tractor always did what I wanted!”

Always looking for a better way
That strong work ethic and an affinity with machinery were two things that would prove critical in Sievwright’s career, as well as the sudden death of his father in his last year of high school. “I realised at that point it was up to me to get going and see what I could do. I got myself an overseas scholarship as an Engineering Cadet with General Motors New Zealand and later in Flint MI, which is where I did my Engineering degree, and learned all about car manufacturing. I came back in 1974 and got the chance to start my own company.” Not Trimax. It would be another eight years before Sievwright moved into the machinery of grass cutting. Before then he would hone his business, sales, marketing and export skills making meat hooks for local abattoirs from hardened and tempered spring steel.

On one of his meat hook business trips in 1981, 33-year old Sievwright spotted a flail mower with a blade made from two steel pieces welded together. “I sat down and sketched a blade that I knew we could make from just one piece of steel and sent it to the manufacturer. He liked it and we got an order for a thousand blades: my first order for the Gamma flail!” That particular mower manufacturer bit the dust a couple of months later and Sievwright’s blade deal fell through, but he wasn’t fazed. He decided to up sticks, move his business and his young family to Tauranga, New Zealand to manufacture the mowers and the blades himself. He hired a mower engineer (Norm Miller, who still works at the company’s HQ today) and went into production. For Bob meat hooks were out and Trimax Mowing Systems was born.

Inspiring productivity
The first Trimax models on the market – Ezeemow, Mowcraft and Mulchmasta – were originally aimed at New Zealand’s booming kiwifruit farming industry. But demand soon grew from park groundsmen and reserve landscapers who had heard of the mowers’ reputation for durability, quality of cut and low maintenance. In 1985 Trimax diversified into rotary mowers and purchased a complimentary mower manufacturing business, owned by Jim McEwen. Sievwright says: “Jim had design skills that I can only describe as an art form. All his mowers looked great and mowed well, so I invited him on board; we worked well as a team and together we had easily the lion’s share of the local municipal market in New Zealand.”

Jim McEwen set up Trimax’s first Research & Development department. He explains the company’s success. “We have always challenged the status quo and offered a fresh approach to mower concept and design. We produce machines that are aesthetically pleasing, exceed the customers’ performance expectations and have a longer life.”

We see possibility
In 1985, Trimax started exporting their pioneering mowers, the Procut and the Stealth to Australia. All part of Sievwright’s vision: “I was determined we would export as I’ve spent almost half my life outside of NZ. Part of the design parameter was always that our mowers had to be internationally saleable, commercial quality products that delivered long-term value. Trimax has succeeded where others failed by offering premium products, premium service and always listening carefully to the end-customer. Jim and I have travelled overseas many times, trying to understand what users need in each market.” After rotary mower Stealth S1 set a new standard of grass cutting in Australia, it came as no surprise when Trimax started exporting to the UK. Brits loved the Stealth S1 too and by the end of the 1990s Trimax had opened their first UK office and warehouse in Northamptonshire. Trimax mowers were now being used in many prestigious locations including Windsor Castle and the ten perfect polo pitches at the nearby 130-acre Guards Polo Club.

But not content with cutting the Queen of England’s lawns, Sievwright set his laser-sharp sights next on the USA. Trimax sold its first rotary roller mower there in 2001 and opened up a distribution warehouse in Georgia in 2005. Tinkering away with America’s grand scale in mind, the research and development team launched the X-WAM in 2009, a 10m-wide monster, like nothing else on the market. The scale, reliability and pristine cut of the X-WAM meets the needs and boosts the profits of the country’s mammoth turf farms. Just Google Trimax X-WAM and wonder at the size of it.

Marketing-led approach
Trimax had hired its first marketing executive in 2001. Before then the business attributed its two decades of growth to great salesmen. “We won a lot of customers throughout the 80s and 90s by demonstrating our products” recalls Sievwright. “When I started there were seven other mower manufacturers in NZ. We had to be different and we had to prove we were better. When you’re so sure you can outperform your competitors, you have no hesitation doing side-by-side battles. We won them all.” Sievwright’s proud of his products’ ability to perform but acknowledges that today’s business environment demands a more marketing-led approach: “We still need to demonstrate as much as possible but we do that while also sharing the Trimax story.”

Innovating with purpose
“Our approach to innovation has always been driven by customers. We listen to how they use their products and design purposeful innovations to help customers achieve their potential”. It was this approach which led to the development of one of the company’s most iconic mowers – the Snake! A fully dedicated sports turf mower, utilising 30 years of innovations and refined engineering practices all rolled into one incredible product. Released in 2014, “the Snake solved many challenges and transformed the lives of many groundsmen across the globe”.

“As a kid I always remembered our farm equipment needing lots of tedious maintenance and how frustrating and costly break downs would be”. His ability to relate and empathise with customers, coupled with his desire to push new boundaries, Sievwright says “the ultimate goal would be to produce a zero-maintenance mower”. With that in mind, Trimax went on to develop an array of innovations, such as; SteadFAST maintenance free spindles, auto-belt tensioners and the LocTEK stubless roller retention system, all focused on bringing Trimax one step closer to the ultimate goal.

Powering performance
With sales continuing to boom, in 2015 Trimax expanded their UK operation by purchasing a 16,279 sqft facility in Northamptonshire, and in 2019, a 25,000 sqft facility in Georgia, USA. With offices now around the world, employment numbers soring to 100, and an ever-expanding community of Trimax users – this was something Sievwright only dreamt of!

With Trimax still only scratching the surface of what the huge USA had to offer, Sievwright rooted himself in the market and made it his mission to better understand their needs. “Each market that we operate in is truly unique, as are the requirements of each individual. It’s important for us to acknowledge this so that when we are developing mowers, we can be sure they meet these requirements without compromise”. Needless to say, it wasn’t long before Sievwright identified an opportunity – an opportunity to build a new concept of a castor wheeled mower!

Not afraid to follow what the market required, Trimax and the team set about developing their first ever castor wheeled mower, later named – The Vulcan! Having only just been released in the USA market in 2019, this 7m wide mower is sure to impress!

Personal partnerships
Despite taking a step to the side and passing the reins over to the next generation (his son Michael), he still remains a very active salesman (as he describes himself) within the business. “I’m so proud when I see how much the whole Trimax team continue to fight for the customer. It’s what got Trimax this far, and it’s what will ensure we have a long and creative future”

What started out as a family-run business whose innovation was founded on culture and driven by community, is still very much that. A culture of partnerships which challenge the status quo, inspire productivity, and raise the bar on results.

Trimax is proof of what can be achieved when the right mix of culture, partnerships and innovations are put together! It’s only a matter of time before we see the next Trimax mowing innovation enter the market!

Maintaining green space in the COVID-19 environment

Maintaining green space in the COVID-19 environment

With varying levels of business restrictions in place globally, one thing has been a constant message – self isolate but make time to get outside and exercise. The importance of lone or household visits to green spaces will provide benefits to mental and physical health within the community for the foreseeable future.

We’ve received a number of enquiries regarding advice on developing low input maintenance practices for turf surfaces as staff availability continues to be unknown.

What is known, however, is that turf maintenance professionals are a resourceful and proactive bunch and no more has this been called upon and tested in the current climate. The Covid-19 crisis and subsequent government responses to reduce its impact have forced many facilities and clubs in our industry to assess their business holistically, including turf management operations.

It has been extremely encouraging to see, over the past week, facilities working together to develop plans to remain operational and provide their local community with the significant resource we know they provide. We have seen split shift arrangements with maintenance crews, implementing social distancing practices, increasing hygiene standards with equipment and taking innovative measures to reduce the possibility of community transition of the virus.

Here are some mowing tips which may help:

• Reduce the frequency in which surfaces are cut.
• Develop a plan to assess which surfaces are to be maintained in their current format and those that can be adjusted.
• Raise mowing heights on all surfaces 20-40% to assist in reducing turf stress. Slow-growing turf may only require mowing once a week or even once a fortnight. Increasing the height of cut on sportsfields or fairways by 25% will reduce the stress on the turf dramatically and ensure grass requires less maintenance long term.
• In regions where cool season grasses are coming into the new season consider raising cut heights higher than usual, i.e. 3.5 inches as opposed to 2.5 inches.
• In regions where warm-season grasses are soon to be entering dormancy, there will be ample opportunity in spring and the next growing season to bring surfaces back to a suitable level through regular renovation practices.
• Use large efficient mowers which will allow you to effectively manage large turf areas with the added benefit of reducing fuel costs.
• Where practicable, maintain surfaces with similar machines. This may mean temporarily changing the shape of surfaces or potentially maintaining multiple areas at one height.
• Reliability of machinery comes hand in hand with preventative maintenance. Ensure a regular maintenance regime remains in place as per your machinery operator manual.
• Minimise downtime by notifying your maintenance department early of faults or damage before it worsens.
• Plan measures to reduce the possibility of touching contaminated surfaces. Set up a transfer system – drive into a depot and enter the tractor cab without the need to be in contact with other personnel. On return to the depot, park up the tractor and enter your own vehicle to leave the depot. This eliminates the need to occupy communal vehicles which would typically carry or tow smaller mowers from site-to-site.

Trailing skids made from abrasion-resistant steel extends bearing life and enables productivity in challenging environments.



Front semi-pneumatic castor wheels allow the FlailDek FX to follow ground contours independently from the tractor.



Safety is paramount when mowing in public areas. The FlailDek FX expels debris in a downward direction behind the mower.



Trimax turf tyres help distribute the weight of the mower for less ground disturbance.



As the rear deck is located between the rear transport wheels, grass is not flattened by the wheels prior to mowing, a feature unique to Trimax.



Contour following and cut quality is compromised when decks are over 3m wide. The X-WAM features multiple smaller decks for superior cut quality.



The X-WAM uses full hydraulic operation for deck retraction into road transport mode.



All moving surfaces have long life synthetic bushes, or greasable bearings and remote grease points for hassle-free maintenance.



Comes standard with a 1/2” heavy duty roller. Suitable for more demanding applications such as roadsides.



SteadFast Sealed Spindles have eliminated the tedius task of regular greasing. Snake now also features maintenance free pivot bushes.



Clearly displayed cut height indicators allow for simple and easy alteration or resetting of cut heights. You can adjust heights without having to raise and lower the wings.


The Trimax Topper has more spindles than comparison shaft driven toppers. These also spin at higher spindle speeds with shorter blade beams. This results in significantly more cuts per forward meter of travel and a much finer clip.



A patent pending stubless roller bearing system for vastly improved retention, bearing life and replacement ease.



Skids on Warlord trailing arms prolong mower life in demanding terrain. The skids can be moved and replaced when required.



Topper spindles are fitted with a unique anti-block mechanism which deters long grass from catching and binding around the spindle restricting movement.



Topping can be used to control poor quality pasture components such as removal of seed-heads and thistles and prevent their reoccurance.



Topper is short front to rear and mounts close to the tractor; allowing the use of smaller tractors. The high underbody clearance and open deck design allows for good flow of grass into the mowing deck and a clean ejection of cut grass.



With only 4 carefully positioned grease points and robust spindles with sealed ball bearings, the Trimax Striker has incredibly low maintenance requirements.



Striker exceceds international safety standards and is backed up by our meticulous testing and support network. Striker is a mower that can be used with confidence even when mowing in confined areas.



Striker incorporates decades of experience with multi-spindled rotary roller mowers. Designed to complement compact tractors, Striker retains the attention to detail that minimises downtime and makes servicing easy. The cutting system, body integrity and sealed ball bearing spindles have been proven with extensive and rigorous testing.



We’ve eliminated the need to grease the pivot points and our updated spindle technology requires less maintenance and offers greater simplicity. You can spend more time mowing and less time maintaining!



The improved belt chamber design includes front openings, allowing grass to be easily washed or blown out.



Trimax’s unique and protected spindle technology ensures spindle height is perfectly aligned across the length of each deck, providing the most accurate and consistent cut in the market.



To ensure optimum efficiency we’ve reduced the number of grease points by 15%, giving you 35% less maintenance costs than the Trimax Pegasus S3.



We build mowers that last and they’re supported with a 3 year industry leading warranty. Our robust design, coupled with our experienced service and support network, ensures minimum downtime and maximum productivity.



Safety is paramount when mowing in public areas. This is why Trimax has designed the Ezeemow FX to expel debris in a downward direction behind the mower.



Somewhat of an operators dream, these spindles offer extremely low maintenance and remove the regular task of regular greasing. As such, costs are reduced and productivity is enhanced.



Coarseness of mulch is controlled by the height of the rear flap. The finest mulch is produced with the flap in the lowest position, this low dispersion also improves safety in public spaces. Lifting the flap fully open whilst servicing provides uninhibited access to flails and rotor.


The Warlord S3 can be positioned directly behind the tractor or quickly offset by up to 19″. This feature assists with transport and manoeuvring around obstacles.


Helps direct prunings and other foliage into the front aperture of the mower, which would otherwise be too high or wide. It also helps keep debris away from the hydraulic system for protection in challenging environments.


A 1/4″ replaceable internal liner reduces noise and minimizes outer body damage prolonging mower life.


The improved cutting chamber and baffle design directs airflow from the blades out and over the rear roller. This improves cut quality and spread in both long and short grass.



Enables all three mower decks to be raised without disengaging the PTO to traverse driveways, paths and curbs.



Eliminate the need for belt adjustments and improve drive to the spindles blades.


Allows continuous cutting while turning sharply for maximum productivity.



With three articulating decks the Snake has the ability to follow contours with minimal scalping.


Clearly displayed stainless steel height indicators allow for the easy adjustment of cut heights without having to raise or lower the wings.


A large diameter rear roller on the ProCut follows the contours and supports the mower across its entire width, providing excellent anti-scalp protection. A pair of castor wheels support the front of the mower.


Provides safe and easy access tot he rear of the tractor when coupling the mower.



Provides easy access for removal of grass and drainage of water from belt cavity.


Full width rollers on all decks follow the contours of the ground and provide excellent anti-scalp protection. Rollers also allow mowing along the edge of banks or paths, and produces a superb striping effect for those wishing to pattern their turf. Safety is enhanced as rollers contain debris in the cutting chamber.


Clearly displayed cut height indicators allow for simple and easy alteration or resetting of cut heights.


With their unique ’tilt forward’ design, carefully engineered centre of gravity and optimised blade thickness, LazerBladez achieve a superior cut and finish. They’re also cost efficient compared to reels or solid blade beams as only the fling-tip requires replacement.



Full width rear roller prevents scalping, permits the edge of the mower to be run along kerbs, adds to overall safety and produces striping.



Designed to withstand the toughest environments our new rotor is more durable ensuring downtime is kept to an absolute minimum.



When in a downward position the converter creates suction, which lifts grass for a superb cut. For work in heavy grass, lift converter for increased grass intake.



A stubless roller bearing system for vastly improved roller retention, roller alignment, increased bearing life and minimal maintenance. Includes our new increased strength tri-bolt bearing housing.
