A reaping transmission shaft, to which power from an engine is transmitted, is provided on the front of the traveling machine body. The reaping unit has: a reaping input shaft, which is provided side by side with the reaping transmission shaft in the up-down direction and inputs power to the reaping unit; and a forward-reverse switching device for transmitting power from the reaping transmission shaft to the reaping input shaft. The forward-reverse switching device is configured to switch between a forward state in which forward power is transmitted to the reaping input shaft from the reaping transmission shaft via a transmission path and a reverse state in which reverse power is transmitted. The forward-reverse switching device is disposed on the side of the traveling machine body towards the end of the reaping transmission shaft.

Abstract

A transplanter (P) comprises a control unit (36) with which it is possible to execute: a target direction setting process for setting a target direction (L0) by causing a traveling machine body (1) to travel in one direction; and a straight-travel control process for causing the traveling machine body (1) to travel in a straight line along the target direction (L0) on the basis of the position of the traveling machine body (1) detected by a position information detection unit (56). The control unit (36) executes the straight-travel control process on the basis of a planting clutch being switched from a disconnected state to a connected state after execution of the target direction setting process and the start of a turning operation of the traveling machine body (1).

Abstract

A sash member is secured to a first frame member and a second frame member (35) in a first position and a second position positioned on one side and another side sandwiching a plurality of threshing teeth (15) in the circumferential direction, and is secured to a third frame member (36) in a third position positioned between the first position and the second position in the circumferential direction via a securing member in which a first slot that extends in the radial direction is formed. The cross-sectional area (G) intersecting the third frame member (36) in the axial direction is smaller than the cross-sectional area (H) intersecting each of the first frame member and the second frame member (35) in the axial direction. The weight of the third frame member (36) is thereby reduced, and it is possible to obtain a threshing cylinder 11 that can be driven with a low drive force.
