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.

Light riding vehicle with variable friction drive

A lawn mower has a dual-tubular frame for shock absorption. The dual-tubular frame has two parallel, longitudinally-extending tubular structures with curved portions allowing for flexion. A seat bracket interconnects the tubular structures. An engine is mounted to the tubular structures rearward of the seat bracket.

A riding lawn mower may include a cutting deck coupled to a cutting blade, an engine, a deck drive coupled to the engine to receive power for operating the cutting blade, a ground drive coupled to the engine to receive power for movement of the riding lawn mower over ground, and a friction drive coupling the deck drive to the engine.
