The product fits machines with CAT-style rear attachment (characteristic different pin diameters).
The ripper has pressed-in bushings. Two pins are required for mounting: one 45 mm and one 50 mm diameter (usually already on the machine). The replaceable tooth tip is included (CAT J system).
When working with a ripper, huge forces are concentrated on a small area. Be especially careful not to snag the machine stabilizers or cab when pulling the arm in. Always ensure the ripper is securely locked in the quick hitch.
The ripper is used for penetrating and breaking up hard ground (frost, rock, asphalt, roots) that a standard bucket cannot handle. It prepares the ground for further digging.
