Meet Gyro
The origin of the species
Zero Turn mowers have been around since 1964. To achieve ‘zero turn manoeuvrability’ the differential steering is managed by two control levers. This mechanical system is commonly used by the military to drive tanks and was also adopted for tracked vehicles such as bulldozers and some tractors.
The evolution of the species
One thing that hasn’t been challenged over the years is the way that these machines are steered. Nearly 60 years later, they still mostly use two levers – this requires constant adjustment and steering in a straight controlled line can be extremely difficult. Not an ideal experience when mowing lawns at speed.
A revolution for the species
Getting used to the control levers and steering capabilities of a zero turn mower can be tough. Mastering it, even harder. For ordinary gardeners these machines can be intimidating, with an underlying fear that they might lose control and cause some unwanted damage.
And that is why Stiga engineers set about exploring a new and more intuitive way to steer a new kind of mower with greater manoeuuvrability, high efficiency and improved productivity. They succeeded. Their machine is called Gyro, and it’s a joy to steer.
Battery-powered, energy-efficient and safe, the STIGA drive-by-wire joystick system is much easier to use for both first-time zero-turn drivers and for those who are used to steering stick controls.
It’s intuitive, intelligent and easy to manage. The whole driving system is smooth but responsive and allows the user to fully govern the machine’s direction, steering and speed with the flick of a wrist.
Safety first
With clever weight distribution and a very low center of gravity (just 55.3 cm) Gyro has been developed and tested to operate safely and on inclines up to 15° – but tested to ensure a greater safety margin (roughly +20°) in comparison to the suggested use of the machine.
Electronics automatically manage speed limitations when working on slopes, for added safety. The patented Direct Drive technology also includes a saftey brake.
Designed around any kind of user
Stepping in and out of Gyro is easy: a completely unobstructed access and a wide footboard giving plenty of legroom. Complete visibility over the working area and all electronic controls at your fingertips.
For added comfort the high-back-support-seat also has a dual parallel suspension system to absorb vibrations when traveling over bumpy ground.
But the real comfort comes from the feeling you get from being safely surrounded by a cockpit that fits around and supports you on three sides. Gyro holds you in, safely.
High-area productivity
With up to 108 cm-wide side-discharge cutting deck, plus optional mulching kit, Gyro has been engineered for huge lawns.
This is made possible by the integrated STIGA ePower battery pack. It provides up to 110 minutes of runtime – enough for you to mow up to 8,000 sqm on just one charge.
The STIGA Gyro axial mower is built around its unique STIGA Direct Drive technology. Dual independent electric transmissions, one for each wheel, positioned in line and equipped with powerful 1.25kW brushless electric motors, allowing both a 360° turning radius (no uncut spots) but also the highest energy-efficiency.
To achieve this, STIGA engineers developed the system with a planetary gearbox. In this system, internal loads are better balanced and distributed, so wear and tear is dramatically reduced. When compared to a normal gearbox with the same transmitted power, the Gyro’s overall efficiency is above 85% (vs. around 78%).
The deck height can be easily adjusted to eight different cutting positions using the lightweight assisted lift mechanisim – reducing the effective weight of the deck up to 6 kg.
STIGA Smart Cutting Mode allows you to choose from three blade speed settings: Eco (2.800 rpm) for very frequent mowing of soft grass or if you choose to mulch regularly; Standard (3.000 rpm) for the usual weekly sessions and cuts up to 2.5 cm; and Boost (3.200 rpm) for quicker cuts or thicker, taller grass.
Gyro allows you to combine the cutting and driving speeds to suit a variety of different mowing needs. Choose between Comfort at 3.5 km/h for a more precise trim. Standard for your regular cutting sessions. Or Performance, for faster results driving at speeds up to 12 km/h.
For each of the speeds, Gyro automatically limits the minimum and maximum speeds and applies different acceleration curves. This way, you will always feel comfortably in control and confident – regardless of the speed you choose.
ePower integrated battery pack
STIGA ePower batteries are designed, developed and tested far beyond industry standards to deliver longer run-times and longer life span. They’re tested at a ‘real-life’ usage current to stay strong after 500 charging and discharging cycles. This equates to 10 years of weekly machine usage.
Using the larger 21700 cell format with higher quality chemistry used in the automotive industry for the best possible efficiency – STIGA ePower integrated battery cells powering the STIGA Gyro give performance and reliability that’s very hard to beat.
