Abstract
A yieldable door latch for holding open the door of a tractor cab in which the fender adjacent the door is of a width comparable to the width of the door, the door latch being mounted adjacent the outer edge of the fender so as to engage the under side of the door at a point close to the outer edge of the door. The door latch has biasing means located beneath the fender for biasing the door latch upwardly and has two inclined surfaces inclined upwardly from the outer and inner ends of the latching member to a central notch which is designed to receive the lower edge of the door. This biasing means is located beneath the fender and has an adjustable stop for limiting the upward movement of the latching member so that the outer end of the latching member always lies beneath the path of the lower edge of the door. The latching member preferably extends generally parallel to the outer edge of the fender and has a downwardly extending flange extending down beside the outer edge so as to guide the movement of the latching member. The latching member is provided with a flat portion to be engaged by the foot to enable the latching member to be pushed down to release the door.
