Ideal for sports pitches and lawns producing the enviable ‘Dennis Stripes’.

The Dennis PRO 34R is a high-performance petrol-powered rotary mower designed exclusively for export markets outside the UK and Europe. Built for professional grounds maintenance, it is engineered to deliver a superior finish across large sports turf and amenity grass areas where both presentation and efficiency are essential.

The PRO 34R combines powerful cutting performance with an advanced vacuum collection system that efficiently lifts and removes clippings, debris and surface material in a single pass. This makes it particularly effective for post-match pitch clean-up and routine maintenance across heavily used playing surfaces.

With a 34” (860 mm) cutting width, the PRO 34R is ideally suited to football, rugby and cricket pitches, as well as ornamental lawns and managed green spaces requiring a consistent, high-quality striped finish. Its rotary design, combined with controlled airflow collection, ensures a clean, professional appearance even in demanding conditions.

Testimonials

  • “The Dennis Pro 34r has dramatically aided the clean up and presentation of our heavily used pitches. When you’re looking for a collection mower there really isn’t any better mower than this in my opinion. It speaks volumes seeing countless professional setups using these mowers and we couldn’t wait to receive ours. A massive edge in our machinery fleet, especially this morning after a pro clubs double session and leaf fall yesterday. It helped gain an applause from the coaches on their arrival following a single cut this morning”

    George Sheath

    Head Groundsman, University of Southampton

  • “I’m really impressed with the quality of cut these mowers deliver-the finish is absolutely outstanding. The customer service from Dennis is just as exceptional as their products.”

    Jack Charles

    Head Groundsman Bedford Blues Rugby Club

  • “We chose the Dennis Rotary because, out of all the rotary mowers on the market, it felt the best built and the most reliable. It leaves a great finish, clears debris brilliantly after games, and handles wet grass really well. The different gear options make it easy to work at the right pace and the suction and brush system clean everything up efficiently. Height adjustment is simple, the striping quality is excellent, and overall it’s a machine I’d definitely recommend to football and cricket clubs looking for a reliable, high-quality rotary mower.”

    Tom Hudson

    (TH Sports Turf Solutions Ltd) and Head Groundsman Teddington CC

  • “The Dennis PRO 34R rotary mowers have completely transformed the way we work. Tasks that previously took six staff a full eight-hour day can now be completed by three staff in just two hours, which has freed us up to focus on other important pitch maintenance jobs. The presentation and finish they deliver is first-class, the height adjustment is incredibly precise, and the brush system does an outstanding job of cleaning debris. There aren’t many mowers that can offer such a high-quality clean, cut and finish all in one machine. On top of that, the support from Dennis has been excellent -they really listen to their customers and continue to develop technology that makes our working lives easier.”

    Evan Davies

    Head Groundsman Swansea City FC

  • “The Dennis PRO 34R’s are supreme machines. We’ve always known Dennis to be reliable, robust and first class in build quality, and these rotaries are no different. They’ve transformed our efficiency -what used to take four staff around three hours can now be done by three machines in just over an hour. They’re brilliant for cleaning up after games and events, and they give a superb finish with the famous Dennis stripes. The ability to adjust speed and still get maximum uplift, even in damp conditions, makes them incredibly versatile throughout the year. Once you’ve used a Dennis machine, they’re very hard to move away from.”

    Jim Dawson

    Head Groundsman, Murrayfield

  • “The PRO 34R was the machine I wanted most… I’d heard so many good things about it. It’s very impressive… the clean-up is absolutely fantastic and it saves us time. The front brush is excellent – it removes dew and picks up leaves easily. It’s not just a standard rotary mower - it’s far better.”

    Dylan Thompson

    Grounds Maintenance Manager at Colliers Park

  • “The PRO 34R has helped make huge improvements to both the main and training pitches. I needed a mower that would give a great finish and help with clean-up after use – it ticks all the boxes. The sward has thickened and the surface has improved significantly since using it. The finish is like a cylinder mower – the quality of cut is the best I’ve seen on a rotary. It picks everything up and holds a surprising amount in the grass box. It’s simple, reliable, and very easy to use – ideal when working alone and under time pressure.”

    Stuart Vause

    Head groundsman at Castleford Tigers RLFC,

  • “The PRO 34R has transformed the pitch – it’s never been so clean.We were instantly impressed by the speed and the amount of ground it covers.It allows us to clean the pitch with two people instead of four – much more efficient. The vacuum is brilliant – it leaves the surface incredibly clean after matches. We’ve never seen the pitch so clean compared to our old mowers.It gives great presentation and we often use it on matchdays for striping. It’s reliable – we know exactly what we get with Dennis and can get parts quickly.”

    Matthew Hallam

    Grounds Manager, Notts County FC

  • “With these bigger machines you are allowing more staff to go elsewhere to do additional jobs. We are using them straight away after a training session to clean the pitches up. They are using them every day and they have improved the pitches no end. It is a very user friendly machine and extremely adaptable because it has so many different gears. You can get a pitch cleaned up in about 40 minutes with three of you. It is great when you leave the stadium after a match-day knowing everything has been done and everything is clean – it certainly helps me sleep easily! The finish on the rotaries is absolutely superb and you could even use them for a match-day cut because they will provide presentation of the highest quality.”

    Anthony Parker

    Deputy Head Groundsman, Wolves FC
