Aeration and scarification are important operations in the provision and maintenance of healthy turf. In this test we look at a wide range of machines to break compaction and reduce thatch to improve gaseous exchange and water percolation.
We start in the Walled Garden at the Cannington Campus, where we ask David Green to blast air and seaweed into the lawn and the area around the tree planted three years ago by the Earl of Wessex.
Then we move onto the golf course at Cannington Golf Club, part of the college, and put the ATT cassette system through its paces.
The latest Verti-Drain, Toro ProCore and John Deere Aercore are used on the greens. We undertake some hollow coring with the Ryan Lawnaire before using the tractor-mounted ProCore SR.
Finally, we look at two dedicated scarifiers - the pedestrian Charterhouse Pro and tractor-mounted Trilo VCU.

ATT (ADVANCED TURF TECHNOLOGY) TMSYSTEM
The ATT TMSystem is bursting with technology.
The ATT TMSystem is capable of reducing organic matter and aiding gaseous exchange but can also manipulate green speed, integrate top dressing or simply cut the grass.
A high-grade, laser-cut stainless steel chassis holds the cassettes. It is fully compatible with all mainstream makes of triplex greens mowers but we use it with ATT's own INFiNiPower pedestrian unit.
"This is what greenkeepers want," says Murray, studying the traction unit. "It is nicely balanced, you can spin it round at the end and carry on working, and it feels good to use."
The power unit has a floating head mechanism with dynamic return, which constantly spreads the weight of the treatment tool evenly.Changing cassettes takes about 10 seconds. Height adjustment is wrench-less.
The Scarifier Cassette is the choice for thatch removal and has five-knife blades of 1.6mm thickness and at 40mm spacings. The THATCHMaster Cassette prevents thatch accumulation.
There are also the Star Spiker and Sarel Roller Cassettes, the Ultra Groomer Cassette, vibration cassette and powered rotary and static top-dressing brush cassettes. Or you might want a cylinder mowing reel.
