A power machine having a frame and a cab rotatably coupled to the frame at a pivot axis for movement from a working position to a raised position. A first spring and a second spring both extendable from a first length to a second longer length are connected to the frame at opposite sides of the cab to assist in moving the cab from its working position. A third spring is connected to one of the sides of the cab, and is also extendable from a first length to a second longer length. The third spring is coupled to the frame and the cab, and provides an additional assisting force as the cab initially starts pivoting and becomes ineffective as the cab nears its raised position.
