Charterhouse Pro Scarifier

Another good machine for the hire industry and contractors, the Charterhouse Pro Scarifier is well built and simple to use.

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.

The Charterhouse Pro Scarifier rips out material at a good rate. A choice of cutting mechanisms makes it even more attractive.

If you want a fixed-blade rotor, you can have it, complete with 24 1.5mm-thick blades at 20mm intervals. If you want swinging blades - likely to be popular with hire firms - you can have a four-section rotor with 48 3mm-thick hanging blades.

Height adjustment is via a hand-nut at the top of the lever that takes the blades in and out of work. Twin V-belts imply this scarifier is going to be reliable and you cannot go wrong with the Honda engine. We also like the way the handles fold for easy transport.

"It's a good basic scarifier, easy to set up and use, and it's speedy," sums up Murray. "Build quality is good - there's nothing much to go wrong. The solid tyres mean you won't get punctures."

After 20m of operation, Murray has to stop the machine and empty the catcher.
