A blade 5 swinging vertically through a tilt cylinder S3 is pivoted on the support 4 through a longitudinal shaft Z. The support 4 has a sliding part 4B facing the blade 5, at the tip of an arm part 4A projecting laterally outward. A guide member 6 regulating front separation while allowing the vertical swing of the blade 5 is provided on the back of the blade 5. A slide plate 43 coming into slide contact with the sliding part 4B of the support 4 and the guide member 6 are detachably provided on the back of the blade 5.
