PROBLEM TO BE SOLVED: To provide a weeder for paddy field solving problems of conventional weeders such that operators have to adjust the operating depth of weeding of an interrow space-weeding mechanism and an intercrop space-weeding mechanism separately and operation was troublesome and rough work required time. SOLUTION: The weeder is equipped with an operating depth equally adjusting mechanism 10 interposed between the main frame 3 and the supporting base 4 and the intercrop space-weeding mechanism 6 and the interrow space-weeding mechanism 5 are vertically parallelly adjusted by the handle 10b. The interrow-space-weeding mechanism 5 is connected interposing an operating depth relative adjusting mechanism and the interrow-space-weeding mechanism 5 is vertically adjusted to the intercrop space-weeding mechanism 6 by an operating lever 11.
