Patent ID: 6874308

Claim:
A lawn mower which tilts its cutting deck from a horizontal position to a vertical transport position comprising: a tractor frame including a power source, drive wheels driven by the power source and steering means; a carrier frame pivotally mounted to the tractor frame on a horizontal axis parallel to the path of movement of the mower; a single cutting deck including multiple cutting blades positioned under the carrier frame and supported therefrom; a pair of castered wheels mounted on the carrier frame, one on each side for ground support; a horizontal leg supporting one of said wheels pivotally journaled to the carrier frame; a fixed offset link rigidly attached to said leg; a parallel link, one end pivotally attaching to the offset link with the opposite end pivotally attached to the stationary tractor frame providing a parallelogram linkage with the carrier frame and said leg whereby rotation of the carrier frame about its pivot through the parallel linkage retains the caster wheel on said leg from rotating relative to the ground as the carrier frame and deck are rotated upwards towards a vertical position; and, adjustable means supporting the cutting deck to the carrier frame which means lifts the cutting deck up towards the carrier frame as the carrier frame and cutting deck begin to rotate.
