Abstract

A machine for excavating rock includes a frame, a cutting device, and a boom. The cutting device includes a cutting disc having a cutting edge, and the cutting disc is rotatable about a cutting device axis. The boom supports the cutting device and includes a first end, a second end, and a boom axis substantially parallel to the cutting device axis. The boom further includes a first portion and a second portion. The first portion is coupled to the frame for rotation about a first pivot axis between a raised position and a lowered position. The second portion is coupled to the cutting device, and the second portion is pivotable about a second pivot axis between a raised position and a lowered position.
