Title:
OPERATING DEVICE OF COMBINE HARVESTER
Document Type and Number:
Japanese Patent JP3839827
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To improve operability and operation efficiency in travelling speed change and turning operation.
SOLUTION: An operating device of a combine harvester is designed so that a travelling speed is changed and a machine body is turned by operating a hydraulic speed change mechanism with a change lever and operating a hydraulic steering mechanism with a steering handle, wherein the device has an interlocking means for integrally interlocking and connecting a speed change operation member which is operated by the change lever with a steering operation member which is operated by the steering handle, and further has a body speed reduction means which reduces the travelling speed of the machine body according to a steering amount given by the steering handle. Therefore, the operability and the operation efficiency are improved in the travelling speed change and the turning operation, for example, by accurately outputting operating forces required for the speed change and the turning operation from each of the operational members integrally mounted in one position near a driving operation area.
