Abstract

A riding-type working vehicle comprises a key switch (34) for starting and stopping an engine, an operation piece separated from the key switch (34), an engine stopping unit (72) for stopping the engine based on the action of the operation piece, when the key switch (34) is used for carrying out a starting operation. The riding-type working vehicle includes a sustaining unit (74) which sustains the action of a motor (32) which drives a fan (31) of a heat radiator (30) to rotate even when the engine is stopped by the engine stopping unit (72). The riding-type working vehicle is structured in such a manner that when the engine is stopped through the action of the operation piece instead of the key switch, the engine can be prevented from being overheated.

Description

technical field [0001] The invention relates to a ride-on work vehicle such as a ride-on rice transplanter and a ride-on direct seeding machine. Background technique [0002] In a riding-type rice transplanter which is an example of a riding-type work vehicle, there is a structure as disclosed in Patent Document 1: a shift lever (corresponding to another operating member) for operating a shifting device for traveling The operation path (neutral position) of the engine is connected to the stop position of the engine. When the key switch is turned on, if the gear lever is operated to the stop position, the engine will automatically stop. In this case, when the key switch is turned on, if the shift lever is operated from the stop position to another position, the engine is automatically started. [0003] Therefore, when there are few seedlings on the seedling loading platform during the cultivation operation, the engine can be stopped without operating the key switch by operat...
