A lawn mower comprising a frame, an engine mounted on the frame, and a cutting deck mounted on the frame. A wheel mounting structure is pivotally connected to the frame and rear wheels are mounted on the wheel mounting structure wherein the pivotal movement of the frame with respect to the wheel mounting structure raises and lowers the frame with respect to the wheels thereby raising and lowering the cutting deck. A lever mechanism is provided for pivoting the frame with respect to the wheel mounting structure to thereby raise and lower the frame with respect to the wheel mounting structure and a rod and plurality of holes are provided for fixing the position of the frame with respect to the wheel mounting structure at any of a plurality of predetermined positions. The lawn mower has hand controls for controlling a wheel driving system with a motor coupled to each wheel and a safety mechanism is provided to prevent extreme turning which may result from the movement of the hand controls to extreme positions. Further, the front wheels of the lawn mower are positioned in an area in which the rotating blades cut from front to rear to thereby provide more even cut of the grass.

Lawn mower with safety means

A lawn mower comprising a frame, an engine mounted on the frame, and a cutting deck removably mounted on the frame. A wheel mounting structure is pivotally connected to the frame and rear wheels are mounted on the wheel mounting structure wherein the pivotal movement of the frame with respect to the wheel mounting structure raises and lowers the frame with respect to the wheels thereby raising and lowering the cutting deck. A lever mechanism is provided for pivoting the frame with respect to the wheel mounting structure to thereby raise and lower the frame with respect to the wheel mounting structure and a rod and plurality of holes are provided for fixing the position of the frame with respect to the wheel mounting structure at any of a plurality of predetermined positions. The lawn mower has hand controls for controlling a wheel driving system with a motor coupled to each wheel, in which a cover is provided for covering the linkage between the hand controls and the wheel driving system to protect the linkage from various hazards. Further, the front wheels of the lawn mower are positioned in an area in which the rotating blades cut from front to rear to thereby provide more even cut of the grass.

Lawn mower

A lawn mowing machine of a self-driving type having a rotating and stopping device for a lawn cutting blade and a driving and stopping device for the machine body, in which a gripping lever for on-and-off operations of the rotating and stopping device for the cutting blade is operable independently of a gripping lever for on-and-off operations of the driving and stopping device for the machine body, while the latter-mentioned lever, when it is gripped, is engaged with the former-mentioned lever to move it in an operative direction, thereby maintaining it in an operative state.

Improved decompression-type, four-cycle internal-combustion engine which has the conventional compression chamber, reciprocable piston, and intake valve therein; comprising, in accordance with the invention, means for delaying the closing time of the valve, in the course of the compression stroke, with the piston moving upwards, for obtaining reduced compression pressure; and means for closing the valve to its at least nearly closed condition within the closing delay period. The inventive delaying and closing means is preferably embodied in a specifically shaped cam for controlling the operation of the intake valve, with respective depressed, slightly protruding as well as flat portions at preferred, predetermined crank angle positions.
