A mower has features that allow it to mow directly over a flexible marker shaft without damage to the shaft. The mower has front and rear rollers mounted directly in front and behind each blade. These rollers engage the ground in rolling contact and support the housing. The rollers are spaced together a distance less than the height of the marker. The front roller contacts the marker and causes it to bend over. Before the front roller leaves the marker, the rear roller will be in contact with the marker to keep it in a prone position until the mower passes from the marker.

A mowing apparatus for mowing grass in a grassy area having at least one flexible, resilient marker inserted into the ground of a type which will bend substantially flush with the ground, comprising in combination: a blade housing having a longitudinal axis parallel to a direction of travel of the housing; at least one blade carried in and rotatably driven in the housing; a front guard roller located forward of the blade and a rear guard roller located rearward of the blade, each guard roller extending transversely to the longitudinal axis of the housing at least the full width of the blade; and mounting means for mounting the guard rollers rotatably to the housing so as to contact and bend the marker, and for spacing the guard rollers apart from each other in a longitudinal direction a distance less than the height that the marker protrudes above the ground, so as to prevent the marker from flexing upward into contact with the blade as the mower travels over it. A method of mowing grass in a grassy area which has at least one marker inserted into the ground, comprising in combination: providing the marker with a shaft which is resilient and which will flex sufficiently to allow the marker to bend over substantially flush with the ground; providing a mower with a blade housing having a longitudinal axis parallel to a direction of travel of the housing and at least one blade carried in and rotatably driven in the housing; mounting a front guard member to the housing forward of the blade and a rear guard member to the housing rearward of the blade, with each guard member extending transverse to the longitudinal axis of the housing at least the full width of the blade, and mounting the guard members to the housing so as to contact the marker substantially at a point where the marker enters the ground, and spacing the guard members apart from each other in a longitudinal direction a distance less than the height that the marker protrudes above the ground; rotating the blade and moving the housing over the grassy area; contacting the shaft of the marker with the front guard member, and moving the housing over the marker, causing the marker to bend over substantially flush with the ground to avoid being struck by the blade; then contacting the shaft in its bent over position with the rear guard member as the housing continues to move over the marker, maintaining the shaft in its bent over position as the front guard member passes from the marker, so as to prevent the marker from flexing upward into contact with the blade as the mower travels over it.
