摘要： A control system of a lawn mowing vehicle, includes at least one continuously variable transmission drivingly connected to two left and right wheels, a revolution speed detection unit, an acceleration instruction unit, a parking brake instruction sensor, a lawn mower, and a control device. The control device, during the drive of the lawn mower, stops the drive of the lawn mower after the revolution speed of each of the two wheels or the revolution speed of the at least one continuously variable transmission has become zero (0) or within a predetermined range near zero (0), and during stop control of the lawn mower, drives the lawn mower when a target revolution speed, issued by the acceleration instruction unit, of the two wheels or of the at least one continuously variable transmission is not zero (0) and the operation of the parking brake is not instructed.

摘要： An electric work vehicle includes a traveling motor to drive wheels, a working motor to drive a work machine, a manipulator to direct a target rotation speed of the traveling motor and operation of the work machine, a controller to control the traveling motor and the working motor according to operation of the manipulator, and a temperature sensor to detect temperature of the working motor. The controller maintains or changes a target torque range of the working motor according to a detected temperature of the working motor, and the controller maintains or changes a target rotation speed of the traveling motor so that a calculated output torque value of the working motor falls within the target torque range.

摘要： A transmission structure of the present invention causes, during a period from a time point when a rotational speed of a drive rotational power reaches a predetermined first/second speed stage shift-up start speed until a first/second speed stage shift-up end time point, one of an input-side clutch mechanism pair and an output-side clutch mechanism pair to be in a double transmitting state, and causes, in the double transmitting state, a first clutch mechanism and a second clutch mechanism of the other one of the input-side clutch mechanism pair and the output-side clutch mechanism pair to be shifted to a disengagement sate and an engagement state, respectively, while having frictional plate slid.
