The control assembly is attached at its top to the distal end of the dipper boom of a cutting machine and at its bottom is attached to the blade assembly of a cutting machine, The control assembly comprises a rotatory in the form of an upper and lower plates which rotate together relative to the boom of a cutting machine thereby causing the blade assembly to rotate into a forward facing position into the material to be cut. The control assembly further comprises an adjuster in the form of a plurality of coil springs positioned between the upper and lower plates of the rotatory which serves to adjust the vertical movement of the blade assembly relative to the ground, A center mounting member mounts the bottom of the control assembly to the center of the top of the blade assembly for efficient control of the movements of the blade assembly, A combination angling and attaching portion swivels the control assembly to thereby adjust the angle of the blade assembly relative to the ground and attaches the control assembly to the brush cutting machine, A quick attachment in the form of a plate in rotatable engagement with a mating securing receiver integral with the lower surface of the bottom of the rotatory attaches the control assembly to the blade assembly. A method for controlling the movement of a blade assembly of a brush cutting machine is also disclosed.
