Dennis ES-510 Delivers Electric Performance: Keswick’s two flagship parks – Hope Park and Fitz Park – nestled in the heart of the Lake District in Cumbria, are setting the standard for sustainable grounds maintenance thanks to the exceptional performance of three Dennis ES-510 battery-powered mowers.

The move to electric machinery was spearheaded by Christine Fawcett, Parks Manager at Keswick Town Council, following the council’s bold step to declare a climate emergency. “Keswick Town Council and Keswick Parks declared a climate emergency six years ago,” Christine explains. “So obviously things had to change with fossil fuelled maintenance machinery, and we started looking for battery alternatives.”

The parks team had been long-time users of the petrol-powered Dennis FT510, known for its reliability and versatility – particularly its interchangeable cassette system. When Dennis introduced the battery-powered ES-510, which retained compatibility with the same range of cassettes, the transition was a natural progression.

“We’d built up a full suite of cassettes over the years,” says Christine. “From scarifiers to brushes, verticutter, sorrel roller and cutting cassettes – we rely on all of them throughout the year to deliver high standards of turf care. When the ES-510 came out, it looked like the perfect time to make the change to battery. And because the cassettes were compatible, we didn’t need to start from scratch.”

In fact, Keswick’s parks team became the first users in the UK to adopt an electric Dennis machine three years ago and now operate three ES-510s across both Hope and Fitz Parks.

Hope Park is a popular destination for visitors, featuring a nine-hole pitch and putt course and a large putting green. Fitz Park, affectionately known as the ‘people’s park’, is home to a bowling green, five grass tennis courts, an 18-hole putting course, and serves as the base for local sports clubs including Keswick Football Club, the bowling and tennis clubs, athletics, and cricket. Both parks are owned by charitable trusts and maintained by a dedicated in-house team overseen by Christine.

One ES-510 can handle a significant workload in a single day – cutting the bowling green, two grass-court tennis courts, and nine holes on the pitch and putt – with the battery lasting comfortably through the day. “It gets charged overnight and it’s ready to go again the next day,” says Christine.

The machines play a crucial role in Keswick’s fine turf maintenance regime. Christine explains: “We start the season with light verticutting and brushing to clean the surfaces and remove debris. Once the season starts, we usually verticut every three weeks or so, depending on the weather. Cutting typically happens twice a week, usually on a Monday and Thursday. At the end of the season, we scarify the greens and tennis courts before overseeding in late September.”

For the team, the switch to battery has brought many advantages. “We really like the flexibility – you can adjust the walking pace, set the cylinder speed depending on the task, and even keep track of how far you’ve walked in a day,” Christine adds. “It makes the job easier and more tailored to the person using it.”

Now in their third season, the Dennis ES-510s are proving their worth across Keswick’s green spaces – helping the town meet its sustainability goals without compromising on quality. “The ES-510s have helped us maintain our sports surfaces to a high standard while reducing our environmental impact – and that’s something we’re really proud of.”
