Sale Sports Club groundsman Iain Harrop is embracing the benefits of battery-powered turf maintenance after switching from the petrol FT-510 to the Dennis ES-510 electric cylinder mower.

Dennis Mowers, part of the Howardson Group, welcomed golf industry professionals to Stand 252 at BTME 2026 in Harrogate (20–22 January), where the team showcased a range of professional turf maintenance machinery built to meet the evolving demands of modern golf course management.

Modern turf management demands flexibility. Different seasons, different sports and different turf conditions all require specific maintenance techniques. That’s where the Dennis Cassette System truly shines.
Developed by Dennis, this innovative system allows turf professionals to switch between 16 interchangeable cassettes on a single power unit delivering cutting, scarifying, brushing, verticutting, slitting, sorrel rolling and raking with one machine.
Below is a complete breakdown of each cassette, what it does and the benefits of using it on natural turf.

When Keswick Town Council reviewed how it maintained its fine turf areas, including its bowling greens, the objective was clear: maintain traditional standards of presentation and playability while introducing quieter, more sustainable working practices.
For Parks Manager Christine Fawcett, who manages Fitz Park and Hope Park, which are charitable trusts, any change had to be practical, reliable and low risk. Fitz Park in particular is home to a well-used club bowling green as well as a public green; both of which demand consistency throughout the season.

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.

It has been a season like no other at Oundle School. Not only have the grounds staff prepared surfaces for the school’s extensive fixture list, but they have also supported Northants Cricket Academy, a testament to both the quality and the reputation of the school’s facilities.

Discover the Dennis ES-510 and ES-610 battery-powered mowers designed for precise, consistent cricket pitch preparation. Offering ultra-fine height adjustment, interchangeable cassettes and a powerful 48V battery system, these mowers ensure immaculate turf care with minimal environmental impact. Ideal for cricket grounds, they provide low noise, fast charging and ergonomic features for all-day comfort. Upgrade your cricket pitch maintenance with cutting-edge technology and unmatched performance. Learn more today!
