Abstract
PURPOSE: To elongate the wheel base during the work using a blade and to shorten the wheel base during the work using a scarifier and a front blade by arranging the front frame of a motor grader in the telescopic structure.
CONSTITUTION: After plowed by a scarifier 13, the grojng is evened by a front blade 10 and finally finished by a blade 8. During the work using the front blade 10 and the scarifier 13, a front frame 5 is contracted to shorten the wheel base a between front and rear wheels 7 and 2, so that the vehicle weight may be applied sufficiently to the front blade 10 and the scarifier 13. During the work using the blade 8, the front frame 5 is extended to elongate the wheel base a, so that the vertical displacements of the blade 8 may be limited to about one half of the variation in height of the ground surface and that the ground may be plowed smoothly.
