A steering mechanism 1 for a lawn tractor chassis includes a pivotable sector gear (7, Figure 2) with gear teeth (11, Figure 2), arranged in an arc on a forward-facing edge, meshing with gear teeth on a rotatable steering gear (9, Figure 2(. Nearside 19 and offside 23 steering bars are attached to the sector gear and to nearside and offside steering knuckles 77 that each pivot about respective kingpins 57. A wheel 5 is rotatably attached to each knuckle 77 with each kingpin located outside of the wheel rim of its respective wheel. Rotation of the steering gear causes the sector gear to pivot, whereby each steering bar 19, 23 causes its respective knuckles to pivot about its respective kingpin, resulting in the turning of each wheel. The arc is preferably a circular sector, and the sector gear has pivot apertures for attachment of each steering rod rearward of a pivot aperture 37 of the sector gear.
