Self-propelled working machine
First Claim
1. A self-propelled working machine, comprising:
- a pair of transporting parts;
a working part;
an engine for driving at least the working part;
a main switch for turning the engine on and off;
a locomotion preparation switch that produces a command for moving the transporting parts when turned on and that produces a stop command for stopping movement of the transporting parts when turned off;
a locomotion speed setting member for ordering a target locomotion speed of the transporting parts;
a work switch for switching on and off the working part; and
a control part for stopping the engine when a first condition that the main switch is on, a second condition that the locomotion preparation switch is off, a third condition that the transporting parts have stopped moving and the target locomotion speed ordered by the locomotion speed setting member is zero, and a fourth condition that the work switch is off, are satisfied.

Abstract
A self-propelled working machine has a pair of transporting parts, a working part, an engine for driving at least the working part, and a main switch for turning the engine on and off. A locomotion preparation switch produces a command for moving the transporting parts when turned on and produces a stop command for stopping movement of the transporting parts when turned off. A locomotion speed setting member orders a target locomotion speed of the transporting parts. A work switch switches the working part on and off. A control part stops the engine when a first condition that the main switch is on, a second condition that the locomotion preparation switch is off, a third condition that the transporting parts have stopped moving and the target locomotion speed ordered by the locomotion speed setting member is zero, and a fourth condition that the work switch is off, are satisfied.

15. A self-propelled working machine comprising:
-
a pair of transporting parts; a working part; an engine for driving at least the working part; a first switch for turning the engine on and off; a second switch that produces a command for moving the transporting parts when the second switch is turned on and that produces a stop command for stopping movement of the transporting parts when the second switch is turned off; speed setting means for setting a target speed of the transporting parts; a third switch for switching on and off the working part; first determining means for determining that the transporting parts have stopped moving; and control means for stopping the engine when the conditions of the first switch being on, the second switch being off, the first determining means having determined that the transporting parts have stopped moving, and the third switch being off are satisfied. - View Dependent Claims (16, 17, 18, 19, 20)
