RACK AND PINION STEERING ARRANGEMENT FOR A RIDING LAWNMOWER

摘要

A pinion mounted at the lower end of a steering column engages a rack which is supported for movement laterally of the longitudinal axis of a riding lawnmower. Opposite ends of the rack have respective drag links pivotally mounted thereto. Free ends of the drag links are connected to the ends of respective spindle arms, each of which is rotatable about a vertical axis. Each spindle arm supports a ground- engaging wheel. When a steering wheel joined to the steering column is turned, the pinion displaces the rack. The drag links impart pivotal movement to the spindle anus to cause th e wheels to turn in the direction the steering wheel has been turned.
