Title:
FIELD WORKING MACHINE
Document Type and Number:
Japanese Patent JP3737866
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a field working machine by which even a narrow place such as the edge of a ridge, etc., is cultivated without leaving uncultivated land and work precision and work efficiency are improved by moving the position of a gauge wheel to the inside/outside of a working area in accordance with work environment.
SOLUTION: The gauge wheel 21 is provided in the tail of a working machine such as a bottom plough working machine, etc., a gauge wheel arm 22 fitted in a plane including a work advance direction with a support pin 24 in a perpendicular state and a hydraulic cylinder 27 capable of rotating the gauge wheel arm 22 within the plane including the work advance direction with the support pin 24 as a center are also provided and the position of the gauge wheel 21 is moved to the inside/outside of the working area in accordance with work environment in configuration. It is desirable that the hydraulic cylinder 27 changes the position of the gauge wheel 21 by one process in extension/ contraction.
