A wheel for a lawn mower, or the like, is positioned on an axle. The axle has a detent groove formed in it. A chassis for the axle has two spaced apart walls with aligned sets of holes into which sets of holes the axle may be selectively inserted to adjust wheel height. A detent spring formed at one of the walls resiliently self-biases to engage in the detent groove in the axle to hold the axle in place. A cutout in that wall holds the detent spring and enables it to resiliently self-bias into the groove in the axle. |
