Abstract

In entering a rice paddy, a harvesting operation on rice poles can be performed smoothly through transmission control of a hydrostatic continuously variable transmission device for advancement, harvesting, and transportation. When the transmission operation position of a transmission stick (70) detected by an operation position detection device (71) departs from a neutral zone (T) where the neutral zone (T) has a specified width and is set at an intermediate position of the transmission operation zone of transmission stick (70), a first hydrostatic continuously variable transmission device (20) performs automatic transmission operation corresponding to the transmission operation position of transmission stick (70) so that a second hydrostatic continuously variable transmission device (21) performs automatic transmission operation synchronous to the advancement speed detected by an advancement speed detection device (73), and the output of above-mentioned second hydrostatic continuously variable transmission device (21) starts automatically when the above-mentioned transmission stick (70) is operated within the neutral zone (T) and detected to be in an advancing state by the above-mentioned advancement speed detection device (73).

Description

technical field [0001] The present invention relates to combine harvesters. Background technique [0002] Conventionally, the following combine harvester is known. As shown in the following patent document 1 (Japanese Patent Application Laid-Open No. 2004-113131), the harvester has: a threshing device arranged on the upper side of the traveling device; The harvesting device on the front side of the harvesting device; the supply and conveying device that supplies the grain stalks harvested by the harvesting device to the threshing device; the hydrostatic continuously variable transmission device that continuously changes the output of the engine and transmits it to the traveling device; and The output of the engine is continuously variable and transmitted to the harvesting hydrostatic continuously variable transmission device of the harvesting device. [0003] The invention described in the above-mentioned Patent Document 1 is configured to detect the operation position of t...
