For very hard soils mixed with rocks. The turning points are equipped with heavy duty bearings. The bearings are double sealed to prevent entering dirt into the bearings. The inner side of the scales is smooth, without any abrupt transitions. This minimises the resistance during the digging in to the bottom and also makes it easier to unload sticky materials, like clay. The knives are manufactured in a round shape for more strength and more impact into the very hard bottom grounds. For hard layers and different to penetrate materials, we recommend knives with teeth. The grabs are executed with knives with interchangeable teeth The grabs can be fitted with a hydraulic rotator for 360˚ rotation or with a mechanical rotator 270˚ rotation.
