Abstract

The riding mower chassis of this invention has laterally spaced front traction wheels, attachment fittings for a mower that rides in front of those wheels, and laterally spaced rear wheels that can float up and down to accommodate terrain irregularities, For such floating a rear axle has at its midpoint a pivot connection with the frame whereby its ends can swing up and down, and the rear wheels are mounted on its ends for rotation and for swiveling relative to it. Swiveling of the rear wheels is controlled by an operator seated on the chassis from a steering wheel at its front. A pair of cable stretches that have their front ends connected with the steering wheel shaft extend rearwardly at the underside of the chassis frame to connections with a steering linkage on the rear axle. The cable stretches are guided past transmission elements on the underside of the chassis in guide tubes in which they are lengthwise slidable, but their rear portions are unconfined for flexing that accommodates swinging of the rear axle.
