Testimonials

  • ''Using the ES-34R we can be greener and more environmentally responsible. We can clean up without any disruption to media after games. There’s no pollution for our staff to breathe in and the vibration on the machine is much lower too. From a financial perspective the club is really happy. There’s no engine, so a lot of costs are gone straight away. Over the years, financially, it makes total sense. We absolutely love the screen. We can adjust walking speed, blade speed and choose exactly how we want to clean up or cut. We can also monitor battery life, so the lads know exactly how much charge is left. You can even see distance covered. It just makes everything more controlled and more professional.”

    Matthew Hallam

    Grounds Manager Notts County FC

  • ''Sustainability is a big focus for the school, and the ES-34R delivers. It’s versatile, easy to use, and perfect year-round—from football and rugby pitches in winter to cricket squares in summer. It cleans up quickly after matches, is far more user-friendly than petrol mowers, saves on fuel, and is low-maintenance and reliable—vital when managing multiple pitches. The electric range is a real step forward. Dennis even adapted it to cut to 8mm for our cricket squares. I’m particular about equipment, but I’ve used Dennis my whole career. I trust the brand, the mowers are the best on the market, and I can’t see myself ever changing''

    Andy Richards

    Grounds Manager at Haileybury School

  • "I had a few electric rotaries on demonstration, one of them being the Dennis ES-34R, and the Dennis stood out by quite a way. My favourite feature on it is the toggle switch, which works like a clutch, so you operate that with your thumb, and it's just very easy to use and manoeuvre the machine. They do a brilliant job at hoovering up all the debris. But the finish on the ES-34R is incredible too. You could use the ES-34R on a matchday to prepare the pitch; it is that good. I also like how you can control walking speed, cutting speed and adjust the height of cut very easily.

    Colin Davie

    Head Groundsman, Heart of Midlothian F.C

  • ''“The FAW is passionate about sustainability, and the ES-34R helps us achieve that. Its silent operation means we can cut pitches during training, making our days much easier. The mowers leave a great stripe, collect debris with excellent suction, and even handle wet conditions thanks to the adjustable blade speed. With their size and efficiency, three of us can now finish a pitch in 45 minutes- compared to three hours with our old rotary mowers.”

    James Mathewson

    Head Groundsperson,Colliers Park National Football Development Centre

  • '“I looked at other battery mowers, but it was always going to be Dennis. I’ve always been a fan of Dennis and SISIS—they make the best machines on the market. We replaced our PRO 34R with the electric ES-34R, and while I loved the petrol version, the ES-34R is on another level—the best mower I’ve ever used. For a 34-inch mower, it’s incredibly easy to manoeuvre, and being electric means fewer problems. We’ve used it almost daily without a single issue, and it’s saved us money on maintenance too.”

    Richard Hare

    Head Groundsperson at the prestigious Bromsgrove School

  • “Predominantly, we use the ES-34R on the cricket square during the summer and on the rugby pitches during the winter months. It is such a quick machine - we can cut a cricket square in both directions in 42 minutes and a rugby pitch in less than 4 hours. We can use the ES-34R for about 7 hours before it needs charging. It is such a quick charge too – we put it on charge while we are having lunch and by the time we are finished, it is pretty much fully charged. The ES-34R always provides an equally as good cut, if not a better cut, than most cylinder mowers. Also, it works like a vacuum, so it is picking all the debris up as well. It is a highly efficient mower, leaves a brilliant finish.”

    Oliver Baldi-Turner

    Groundsman, Bromsgrove School

  • “During Covid, we were only allowed to use quieter electric machines after games, and the ES-34R was perfect. Dennis mowers have always been reliable, with great back-up, and this one adds speed and flexibility. The blade settings let us switch between powerful debris collection or a quick full-pitch cut in under an hour. The LCD screen makes adjustments simple, charging is fast, and battery life is outstanding—we can do a full pitch with 70% charge left. The ES-34R leaves a bold stripe, is comfortable to use for hours, and has become a key part of our matchday preparation.”

    Anthony Parker

    Deputy Head of Grounds, Wolverhampton Football Club

  • ''With the ES-34R's there is no noise during post-match clean-up work. They have made a huge difference for staff and stadium events. They are comfortable, quiet and safe for our team with no emissions at the point of use''

    Andy Jackson

    Head of Grounds, Stoke City FC

  • “The ES – 34R battery life is unbelievable, one mower will do a whole pitch and you can still have at least 40% battery life left”
