Abstract: A bottom guard assembly for a machine includes a guard element attached to a frame of the machine using mechanical fasteners. The bottom guard assembly further includes a door member pivotally coupled to an inner surface of the guard element via a hinge element. The bottom guard assembly also includes a torsion bar having a first end coupled to the inner surface of the guard element and a second end coupled to the hinge element. The bottom guard assembly further includes at least one holder element positioned between the first end of the torsion bar and the second end of the torsion bar, the at least one holder element attached to the inner surface of the guard element. The torsion bar is configured to rotate within the at least one holder element during opening of the door member.
