An apparatus and method for adjusting the height of a wheel, particularly a caster wheel, in relation to a structure such as a mower deck of a lawnmower includes a frame member, a hollow guide member, a transverse element, and a lever. The frame member is interconnected between one or more caster wheels and the structure. The frame member includes an angled section disposed along an angled adjustment direction. Spaced recesses are formed in the angled section and arranged along the adjustment direction. The guide member and transverse element are attached to the structure. The angled section is slidable through the guide member. The lever is pivotably connected to the transverse element and includes a locking element. By pivoting the lever, the locking element can be brought into engagement with a selected one of the recesses to fix the angled section at a desired position relative to the guide member and thus the height of the structure relative to a ground surface over which the caster wheel or wheels roll.
