Abstract: A standing lawn mower includes right and left side integrated transaxles for operating the right and left drive wheels independently. The integrated transaxles may include independent hydraulic systems and hydraulic fluid for modularity and reduced risk of cross contamination. The operator support platform is at least partially behind the right and left integrated transaxles.

Abstract: 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.

Abstract: A deck lifting and height of cut assembly for a lawn mower, in which the deck lifting assembly includes at least one movable component and the height of cut assembly includes a height adjustment mechanism having a plurality of stop surfaces. A prop extends between the movable component of the deck lifting assembly and a first stop surface of the height adjustment mechanism to prevent the cutting deck assembly from lowering below a first height. The height adjustment mechanism is adjustable to place a second stop surface in engagement with the prop so that the cutting deck assembly is prevented from lowering below a second height different from the first height. The prop may also be used to maintain the cutting deck assembly in the full-up position during travel of the lawn mower between work areas.
