    Wycliffe Bowling Club Relies on Dennis FT and Razor for Consistent Greenkeeping Performance

    For more than 70 years, Wycliffe Bowling Club has been at the heart of its local community. Established in 1956 as part of a foundry, the club has evolved over the decades, moving twice before settling at its current site in 1992.

    Since then, the facility and its playing surface have continued to develop, supported by a dedicated team of volunteers who take great pride in maintaining the bowling green.

    One of those volunteers is Adam Orr, a member of the club’s greenkeeping team whose responsibilities focus on the technical aspects of turf maintenance, including operating and maintaining the machinery.

Testimonials

  • The FT510 impressed me so much, I knew I wanted another. With the treasurer’s backing, we bought one. I cut the greens 2–3 times a week, keeping them at 10mm in winter and 5mm in season. I verticut every three weeks, alternating with a sorrel roller or brush. The interchangeable cassettes are the standout feature—quick to swap and easy to transport for sharpening. The click height adjuster makes it very user-friendly. I wouldn’t choose any other mower for our greens.

    Duncan Austin

    Head Groundsman at Prees Cricket and Recreation Club in Shropshire

  • ''The green is in great condition and that is partially because of these mowers. We have had our Dennis FT510 for a long time now and it has never let us down''

    John Brand

    Greenkeeper - Topsham Bowls Club

  • ''We like the way the height of cut can be adjusted without using any tools, it is just a simple turn and click''

    Bob Purcell

    Mowing team - Ludlow Castle Croquet Club

  • Our new Dennis FT510 has just arrived from Penrith and it’s already making a huge difference on the green! We replaced our 30-year-old FT510, which used to collect just 1 box with the old 6mm cut - the new machine picked up 7 boxes using the same height of cut! What a difference a day makes — what a fantastic machine!

    Jeff

    Ulverston Cons Bowling Club

  • “If someone comes to our club and asks us how we get our green in such good condition, we show them the FT510. We tell them what we think the advantages are of using it as well as how easy it is to use.”

    Peter Heayns

    St Austell Bowling Club

  • “The new Dennis FT610 has made a huge difference to the quality and efficiency of our ground maintenance. Its versatility and ease of use make it an excellent machine for any cricket club. We chose the FT610 because it allowed us to keep using the cassette system we already relied on, while upgrading to a much more reliable and capable machine.”

    Graham Smith

    Groundsman, Caverswall Cricket Club

  • “Since switching to the Dennis FT610, the quality of cut and the versatility of the machine has been superb. The interchangeable cassette system saves us huge amounts of time and has made a real difference to pitch preparation.”

    James Holdcroft

    Groundsman, Whitmore Cricket Club

  • “The Dennis FT610 has become an essential part of our maintenance programme. It’s reliable, easy to use and the interchangeable cassette system allows us to switch quickly between mowing, verticutting and brushing with minimal downtime.”

    Ryan Middleton

    Grounds Manager, Nottingham Tennis Club

  • "The FT is a brilliant machine. It's lightweight, easy to manoeuvre, incredibly versatile and changing the cassettes takes just a minute. It's reliable, simple to use and ideal for a volunteer team. I would recommend it to any bowling club. Maintaining a high-quality green is what keeps people coming back, and the FT has become an important part of that''

    Brian Hawkins

    Greenkeeper, ,Blaby Bowls Club

  • “We went for the Dennis mower because of the ease of changing the cassettes, the reliability and the value for money. You’ve got a whole range of cassettes that let you do everything you need on the green. Before, all we were doing was cutting. The green was full of thatch and it was slow. Now we’ve got the different cassettes, we can scarify, verticut and carry out all the jobs we couldn’t do before. It’s taken the thatch out, the green is quicker, the grass is thicker, greener and overall it’s made a massive difference.** The FT is very easy to handle and easy to turn at the end of each run. Changing cassettes is incredibly quick. It’s basically just two knobs and you’re done. **I’d definitely recommend it. It’s easy to use, the different cassettes mean you’ve got one machine that does all your bowls maintenance, and it’s made a huge difference to the quality of our green.”

    Martin Pickering

    Greenkeeper Finedon Bowls Club

  • ''The FT range is fantastic, mainly because of the interchangeable cassette system. If I can take one machine and six cartridges to a cricket ground or sports ground, I’m effectively replacing six or seven different machines. That’s a huge advantage when you’re working across several sites. It’s brilliant because you can use several different cassettes within just a few minutes, and with the FT430, FT510 and FT610 you can take the reel out onto the cricket square and swap it for another cassette in about 30 seconds.It’s a really good finishing mower. I honestly don’t think there’s anything that compares to it. As long as it’s set up properly, it gives a fantastic, uniform finish.They’re reliable, easy to maintain and they do the job, day in and day out. If anyone’s looking to buy a mower, I’d definitely recommend a Dennis.

    Andrew Greaves, AJ Greaves Maintenance

    Owner

  • “Our Dennis FT510 is probably around 15 to 20 years old now and she’s worked very hard over the years. We were so pleased with how the FT510 had performed that, when we needed another mower, we stayed with Dennis.It’s a very easy machine to work with. It’s light to use, easy to turn and simply does the job perfectly. The interchangeable cassettes are really important because they allow us to carry out different maintenance jobs, from aeration and verticutting to scarifying and winter cutting.** When we needed another machine, we stayed with Dennis. They’re tried and trusted machines''

    Sue Allen

    Greens Lead, Harperbury Bowls Club

  • ''We’ve had this Dennis mower for over 30 years. We service it every year and it’s still going strong. Even with the original Honda engine, it’s still going strong. We look after it every year and I think it’ll continue looking after us. We’ve got quite a small shed, so having one machine that does lots of different jobs is a massive advantage. It’s very easy to swap from one cassette to another, it doesn’t take up much room and it’s easy to maintain.** We find the Dennis really easy to use. It manoeuvres well around the corners and is surprisingly light when you’re turning at the ends. It’s an excellent machine for inexperienced people. If someone comes down to help, it’s easy to show them what to do and they pick it up very quickly. For anyone looking to upgrade or invest in a new mower, I’d definitely recommend a Dennis. It cuts brilliantly, the interchangeable cassettes make it incredibly versatile, and it’s an excellent piece of kit for any bowling club.”

    Richard Funnell

    Greenkeeper/Volunteer at West Haddon Bowls Club

  • “We selected the Dennis FT because Dennis has been synonymous with reliability and good build quality, and we have not been disappointed. During the main season, we remove the cutting cassette and add in the verticut cassette, which is again easily done. It folds into place and then we screw up the end cap to keep it secure. The adjustment system is the same click system that Dennis has developed, which makes it very straightforward to use. We've got several cassettes, including the cylinder cassette, the verticut cassette, a sorrel roller and a brush. We use the verticut during the cutting season, mainly to catch the lateral growth, and we use the brush before reseeding to brush out the scarifying. The cassette system means we have one main machine but many different applications, which really increases its utilisation''

    Adam Orr

    Wycliffe Bowls

  • “The Dennis FT mower is a real workhorse for us. It does everything we need and, with the cartridge system, gives us that extra versatility. It’s reliable, easy to use once you know how to set it up, and we’ve had very few problems with it. It’s a machine we simply couldn’t do without.”

    Bernie Greenough

    Derby West End Bowls Club

  • “The Dennis FT machines have been incredibly reliable for us. They’re built extremely well and have proven to be very durable, even when they take the occasional knock. We cut our greens three or four times a week during the season, and they start every time. The cassette system is also a huge advantage. We can quickly change between cutting and verticutting without needing multiple machines, which saves us both time and money. The newer FT is also very comfortable to use, with a more upright handle and reduced vibration. I’d definitely recommend the FT machines. They’re solid, versatile and built to last.”

    Bernie Greenough

    Derby West End Bowls Club

  • “We chose the Dennis mower because of its reliability and the versatility of the cassette system. We can scarify, verticut, brush and cut with one machine, which saves us time and space. Since taking over the green ourselves, the difference has been huge. The green is greener, the grass is thicker, and we’ve significantly reduced the thatch, moss and weeds. The mower is easy to handle, quick to adjust and the cassettes are simple to change. I’d definitely recommend the Dennis to other bowls clubs. It’s essentially one complete bowls maintenance machine in one.”
