A floor cleaning machine is described having a first drive head and a second drive head which are both pivotally mounted to a deck. The first and second drive heads are connected together with a link rod. The cleaning width of the cleaning machine can be changed by pivoting the first drive head about a pivot point on the deck. The pivoting movement of the first drive head causes a movement of the second drive head, via the link rod, in order to provide a new separation for the drive heads. |
