Listing Detail Tabs

This "innovative" excavator ripper which not only cuts tree roots and stump roots but also is an extremely versatile general purpose rock ripper is very efficient in most quarry situations from the Igneous rock Blue stone-Brown rock to the Sedimentary rocks Greywacke-Sandstone.
We are able to manufacture the Diggerknife with the correct hitch pick up to suit your excavator and in some cases are able to make it fit more than one excavator.
The blades are manufactured from Hardox 500 grade steel which ensures it will not bend, break, or chip, this super hard wearing material enables it to be machined to a very fine point and cutting edge. This in turn reduces the drag loading on the excavator and the fine entry point of the knife is able to penetrate small gaps and rock fischers to effectively cut / rip its way through most ground conditions.
The Diggerknife makes easy work of the hardest tree roots with its “Saw” like teeth along the leading edge cutting them off below ground level leaving very little ground disturbance except where the stump has been. The Diggerknife used in conjunction with a Tilt Hitch enables the operator to remove a tree stump with even less trouble, he is able to cut down and under to get those big tap roots.
knife is sold standard without quickhitch but knife can be delivered with every coupling you require
