Embodiment Construction

[0018] Some example embodiments will now be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all example embodiments are shown. Indeed, the examples described and illustrated herein should not be construed as limiting the scope, applicability or configuration of the present disclosure. Rather, these example embodiments are provided so that this disclosure will satisfy applicable legal requirements. Like reference numerals refer to like elements throughout. Furthermore, as used herein, the term "or" should be understood as a logical operator whose result is true whenever one or more of its operands is true. Furthermore, the term "lawn care" is meant to refer to any grass maintenance activity and need not be specifically applied to activities directly related to grass, grass or turf care. As used herein, operatively coupled should be understood to mean a direct or indirect connection, in either case such a connection function...

Abstract

A vehicle, such as a riding lawn care vehicle, may include a frame and steering assembly. The wheels of the vehicle may be attached to the frame. The steering assembly may include a steering device operatively coupled to at least one wheel of the vehicle to provide steering input to the at least one wheel based on a position of the steering device. The steering assembly may further include a steering column, a pinion assembly, and a rack assembly. A steering column is extendable from the steering device to rotate in response to movement of the steering device. A pinion assembly may be disposed along the steering column and include at least two pinions of different sizes. A rack assembly may be operably coupled to at least one wheel and the frame of the vehicle to transfer steering input from the steering device to the at least one wheel via the pinion assembly. The rack assembly may include at least two rack portions having different sizes.

Description

technical field [0001] Example embodiments relate generally to steering systems, and more particularly to variable effort steering systems for vehicles, such as vehicles configured to perform lawn maintenance. Background technique [0002] Lawn care tasks are typically performed using various implements and / or machines configured to perform corresponding specific tasks. Specific tasks, such as mowing grass, are often performed by lawnmowers. The lawnmower itself can have different configurations to support the needs and budget of the consumer. Walk behind lawn mowers are generally compact, have relatively small motors and are relatively inexpensive. Meanwhile, on the other hand, riding lawn mowers, such as lawn tractors, can be quite large. In addition to mowing components, riding lawn mowers can sometimes be configured with various functional accessories such as trailers, tillers and / or the like. Ride-on lawn mowers offer the convenience of a ride-on vehicle and a gener...
