Power, Precision, and Performance — An In-depth Look at the Dennis ES-20, ES-24 and ES-26 Battery Fine Turf Mowers
The Dennis ES-20, ES-24 and ES-26 are part of a new generation of professional battery-powered cylinder mowers, combining quiet, low-vibration operation with the precision cutting performance that has made Dennis a trusted name across fine turf sports and ornamental grounds.
Designed for bowls, croquet, tennis, cricket, golf, ornamental lawns and amenity areas, these dedicated cutting units deliver a flawless finish while offering outstanding ease of use, minimal maintenance and zero emissions.
Building on Dennis’ proven mower designs, the ES-20, ES-24 and ES-26 bring electric innovation to fine turf management. Each model is powered by a 48V 1.5kWh lithium-ion battery system capable of cutting over 10km on a single charge. The rapid 2–3 hour recharge time ensures operators can maintain productivity with minimal downtime throughout the working day.
Despite their advanced technology, these machines retain the balance, control and cut quality that grounds professionals expect from Dennis. Their ultra-quiet operation and ultra-low hand-arm vibration (HAV) levels allow comfortable use throughout the day, making them particularly suitable for noise-sensitive environments such as golf courses, bowling greens, schools, local authority sites and residential areas.
