US 2008/0185162 A1 · Motor Grader

Abstract

One ends of respective lift cylinders 11a and 11b are connected to a lifter bracket 7 respectively through first support means 20a and 20b, and other ends of the lift cylinders 11a and 11b are connected to a draw bar 3 respectively through second support means 21a and 21b. The one ends and the other ends of the lift cylinders 11a and 11b are offset from each other in a front-rear direction of the motor grader as viewed from above the motor grader, thereby disposing the pair of lift cylinders 11a and 11b inclined as viewed from a side of the motor grader. With this structure, it is possible to obtain the motor grader in which a height position of each end of the lift cylinders 11a and 11b can be substantially equal to a height position of the lifter bracket 7 as viewed from the side of the motor grader, and a visibility hindrance by the pair of lift cylinders can extremely be lowered.
