FLexGrass, a specialist in high-performance sports surfaces for elite football and professional sports venues, has successfully integrated Dennis battery-powered turf maintenance equipment into its operations as part of a wider commitment to sustainability, efficiency and surface performance.
With more than 10 years of international experience, FLexGrass designs and delivers natural, hybrid and synthetic turf systems for leading clubs and stadiums across Europe. Combining Italian manufacturing quality with advanced turf technology, the company provides complete solutions ranging from construction and renovation projects to innovative hybrid systems such as Vertix and Horizon.
As part of its ongoing development strategy, FLexGrass recently invested in the Dennis ES-860 battery cylinder mower and ES-34R battery rotary mower to support the maintenance of fine turf sports surfaces.

According to the FLexGrass team, Dennis’ long-standing reputation within professional turf maintenance played a significant role in the decision-making process.
“We chose Dennis because of the brand’s strong reputation for professional turf maintenance, reliability and quality of cut.The support and innovation behind the electric range also gave us confidence.”
The move to battery-powered machinery was driven by clear operational and environmental objectives. FLexGrass sought to reduce fuel consumption, lower maintenance demands, minimise operational noise and further strengthen its sustainability credentials across professional sports environments.
“We wanted to reduce noise, fuel usage and maintenance while improving sustainability.Our previous petrol machines required more servicing and created more noise and emissions during daily operations.”
To meet these objectives, FLexGrass selected the Dennis ES-860 — a 34-inch battery-powered turf maintenance system developed for professional fine turf applications. Built around Dennis’ proven interchangeable cassette system, the ES-860 allows operators to cut, scarify, verticut, brush, groom, and surface spike using a single power unit. The machine also features a high-capacity 48V battery system capable of cutting up to three to four pitches on a single charge, alongside rapid two-hour recharge functionality and ultra-low vibration and noise levels.

FLexGrass identified the versatility of the machine as a key advantage.
“We chose the ES860 because of its versatility, build quality and excellent cutting performance on fine turf areas,” the team said. “The interchangeable cassette system was also a major advantage.”
The company continues to maximise the flexibility of the cassette system throughout the season to maintain presentation standards and surface quality across different environments.
“We use different cassettes depending on the application, including cutting and grooming cassettes to maintain presentation and turf quality throughout the season.”
Alongside the ES-860, FLexGrass also incorporated the Dennis ES-34R battery rotary mower into its maintenance fleet. Designed specifically for fine turf mowing and clean-up operations, the ES-34R combines contra-rotating hardened steel blades with high-performance collection capabilities to deliver a clean and consistent finish in both wet and dry conditions. The machine also features programmable LCD controls, adjustable blade and walking speeds, rapid charging technology and low operating noise.
“We chose the ES-34R because it is practical, quiet and delivers a very clean finish while being easy to use in different conditions,” FLexGrass stated.

Since introducing both machines into daily operation, FLexGrass reports consistently high performance across a variety of working conditions.
“Both machines have performed very well in daily use. The quality and consistency of cut are excellent and comparable, if not better, than our previous petrol machines. They handle fine turf extremely well and also perform reliably in more difficult conditions such as wet or longer grass.”
In addition to surface performance, the operational benefits of battery-powered equipment have delivered measurable improvements for both operators and the wider working environment.
“The reduction in noise has been significant for both operators and surrounding areas,” FLexGrass explained. “We have also reduced fuel costs and routine maintenance requirements compared to petrol equipment.”
The quieter operation of the Dennis electric range has also improved flexibility when working in sensitive environments or around active training schedules.
“The lower noise levels allow us to work more comfortably in sensitive environments and provide greater flexibility with working hours.”
For FLexGrass, the transition to battery-powered technology has become an important part of the company’s broader environmental strategy and client offering.
“Switching to electric has strengthened our sustainability approach and helped demonstrate environmental awareness to clients and within contract requirements.”
Following the successful implementation of the Dennis ES-860 and ES-34R, FLexGrass says it would confidently recommend battery-powered equipment to other contractors and sports turf professionals seeking to improve sustainability without compromising turf quality or operational performance.
''We would highly recommend electric equipment to other contractors because of the lower noise, reduced maintenance, lower running costs and strong cutting performance.”
As demand continues to grow for more sustainable and efficient turf maintenance solutions, Dennis’ electric E-Series range continues to support sports turf professionals in delivering elite-level playing surfaces with reduced environmental impact.
