摘要： Riding lawn mowers may utilize friction drives configured with a variable normal force between frictional components. In a riding lawn mower, an internal combustion engine may be coupled to a differential via a friction drive, wherein the friction drive is configured with a variable normal force in order to provide improved power transfer and/or shifting performance.

摘要： To reduce the complexity, maintenance, and cost, and to increase the reliability of a riding lawnmower employing a short turn radius steering system, the riding lawn mower may be configured with a linkage and steering assembly that eliminates or reduces complicated gearing. A riding lawn mower may comprise a link system, pivot brackets, and spindle assemblies. The geometry of the steering system may be configured to provide a turn radius of seven inches or less. Moreover, the geometry of the steering system may be configured to provide Ackerman steering, such that, the inside wheel turns sharper than the outside wheel in a turn.
摘要翻译：为了降低复杂性，维护和成本，并且为了提高使用短转弯半径转向系统的骑马割草机的可靠性，骑马割草机可以配置有消除或减少复杂齿轮的联动和转向组件。骑马割草机可以包括链接系统，枢轴支架和主轴组件。转向系统的几何形状可被配置成提供7英寸或更小的转弯半径。此外，转向系统的几何形状可以被配置为提供阿克曼转向，使得内侧车轮一轮转动比外轮更锋利。
