Renze,
Thats a different use for a duck, over here they are mainly tracked machines, mind you they are working on 6-12" soil then peat. Like i said i would have bought a duck but tracks are still the way togo, and dont forget you can buy rubber pads for tracked machines now.
And not only that but some drivers just cant get on with them, mind you i like them better than tracks, ive had a duck where some people wouldnt have had a tracked machine and got the job done. I and one of my drivers will work the wheel diggers on the road jobs with out using the legs or buckets on the floor just like a duck and still get the job done.
There will always be a place for wheeldiggers in the uk as the are so easy to send here there and everywhere at a moments notice. I see that jcb have just launched their new wheeldiggers with their new engines and a torque converter lock up, well fermec had that about 5 years or more ago. It still wont get me anywhere near a jcb in a long time.
