A pivotable operator support platform is provided for a standing lawn mower. The pivotable operator support platform is part of a platform assembly. A deck lift foot lever is actuable by the foot of an operator on the support platform to raise the cutting deck of the lawn mower. The deck lift foot lever is pivotable with the operator support platform, and about the same pivot axis, between an operating position and a stored position. A latching assembly automatically deflects as the operator support platform is moved into the stored position, and is biased to engage a latch pin to retain the operator support platform in the stored position.
