A new mowing category after more than 80 years: How does the revolutionary Trimmaster™ compare?

For decades, the history of landscape maintenance has relied on the same principles of grass mowing. The fundamental technology of cutting a blade of grass has not significantly changed for more than 80 years, with the market introducing primarily further variations of already established systems.

The Czech brand SPIDER is now introducing a technological breakthrough with Trimmaster™ technology – a brand-new principle of grass mowing. This is not a mere evolution or a cosmetic upgrade of existing machinery, but a new technological category protected by a global patent.

Let’s take a look at how this new category of mowing holds up in a direct comparison with the two most common technologies: rotary and sickle bar mowing.

Comparing three mowing technologies
Rotary mowing: Speed at the cost of damage
The most widespread method, operating on the principle of high RPMs. A rotary mower separates the grass blade using an impact principle.

• Impact on the lawn: The blade is cut coarsely and frays. As a result, the grass struggles to regenerate, turns yellow, and the turf thins out over time.
• Side effects: High rotational speeds generate massive air turbulence that acts like a vacuum cleaner – lifting clouds of dust, causing noise, and sucking in and destroying beneficial insects.

Sickle bar mowing: A clean cut with limits
A traditional system operating on a scissor-like principle, where two jagged blades move against each other.

• Impact on the lawn: It is very gentle on the grass because it cuts the blade cleanly without unnecessary shock.
• Limits: Sickle bars are mechanically complex and prone to damage from stones or hidden obstacles. Operating them is demanding—the mechanism frequently clogs, requires continuous cleaning, and needs frequent adjustments, which creates downtime. They are suitable for tall meadow grass, but practically useless for a precise, low, and dense lawn.

Trimmaster™ Technology: A new method of mowing with respect for grass
Trimmaster™ comes with a completely fresh approach: it utilizes the principle of shearing using slowly rotating cutting blades. It represents an ideal solution for maintaining flat areas and gentle slopes up to 20 degrees, effectively combining high area efficiency with absolute gentleness towards the plants.

• A perfect surgical cut: Unlike rotary mowing, it does not fray the grass blades; it shears them with absolute precision. The grass regenerates instantly, retains its nutrients, and the turf stays denser, more vital, and more resilient.
• An end to dust and noise: Low rotational speed means no air turbulence is created. Forget about clouds of dust. Operation is so quiet that it does not disturb the surroundings and easily complies with the strictest noise limits.
• Protecting biodiversity: The absence of air vacuum ensures that the machine does not suck in or destroy insects living in the grass. This technology was created with maximum respect for nature.
