Founded in 1993, GreenMech has a history of good ideas. The EcoCombi must be regarded as one of the best.

It was one of the first machines from the Warwickshire-based company and it is as good today as it has always been.

Being road-towable and easy to manoeuvre, the EcoCombi is ideal for mobile crews needing to chip and shred on site. It not only deals with the timber side of the business - up to 6in in diameter - but it also has a separate infeed chute to take forkfuls of wet, soggy green waste.

Starting the machine could hardly be simpler - hold down the start button and turn the key for a few seconds. The 35hp diesel engine rumbles into life.

The EcoCombi is not noisy compared with the average chipper. This is largely down to the patented Disc-Blades. These unusual round blades cut down on noise and are less susceptible to damage. By only presenting about one-third of their cutting edge for work, the blades also save time and money when it comes to maintenance. Slackening off the retaining nut on the flywheel and turning the blade through 120 degs to present a clean edge, the period between sharpening can be lengthened considerably.

The EcoCombi rapidly munches its way through conifer, makes quick work of herbaceous debris for the compost heap and does not complain when we give it cardboard.

"It's very efficient and does not seem to have any trouble with any size of material," notes Olleson. The woodchips generated are uniform. The testers suggest the material would be good for spreading on beds for weed control and also for mixing in with compost. Shreddings are fine and should rot down quickly.

Taylor is also impressed. "You get the feeling that reversing the rollers would clear most problems," he says, adding that the loading height of both the chipper and shredder infeeds is comfortable.

The Review Panel - Michael Olleson, garden maintenance, Waterperry Gardens, Oxford
David Taylor, gardener, Waterperry Gardens, Oxford

We all know that we should reduce, reuse and recycle, but when it comes to general organic waste material, which machines are up to the job? Generating a wide variety of green waste from its vast gardens and also its orchards, Waterperry Gardens in Oxfordshire provided a perfect venue for our test.

We looked at the high-performance GreenMech EcoCombi and TS Industrie Super Premium - both designed to tackle 6in wood waste as well the wet, soggy and dirty green stuff from the herbaceous borders. We also investigated the American-built Bear Cat 5in chipper/shredder.

A high-end garden multi-shredder, the Viking GB460, was put through its paces with smaller woody material and a variety of herbaceous material. Finally, we looked at the Jo Beau chipper and the Eliet Major shredder.
Conditions on the day of the test were dry and sunny, although it was a little cool in the morning.
