Glyn Jones - Didcot Bowls Club

We used to have a push along sarel roller but like most clubs there were no volunteers to use it and it spent most of its time in the hedge bottom. The S500 gives us mechanised surface aeration. We can use it as the weather dictates and it keeps the green surface open. Drainage has improved, the plants are healthier and we have noticed a marked reduction in thatch.

Derek Logue - Derek Logue Groundcare, Argyll, Scotland

I use the Verticut TT at 15 bowling clubs across western Scotland. Faster greens is the result. I've hired it out to friends and they've been impressed too.

John White - Greenkeeper - Bannockburn Bowling Club

We've had our FT and 5 cassettes for more than ten years adding cassettes as funds allow. It's easy to use and noticeably improves the quality of the green. We recommend the machine to anyone who visits.

Bill Brady - Chairman - Wollaton Bowls Club

Our Dennis has done a lot to improve the quality of speed and running of the green. There was a
noticeable difference within a month of buying it. We're over the moon.

Dave Bracey - Turf Consultant to the IOG, EBA, BCGBA & WCGBA

Surface spiking is essential to break the pan of any fine turf. Healthy grass plants need air to their roots to thrive, keeping the surface open. Regular spiking with the S500 - weekly ensures open greens.
