PURPOSE:To make carrying goods not to be dropped by keeping a carrier at a fixed posture even if a tractor is tilted at the time of crossing over a footpass between rice fields. CONSTITUTION:An inclination of a carrier more than a predetermined one in a longitudinal direction is detected by an inclination detector 19 and a top link 11 is expanded and contracted by operating a valve 25 through electromagnetic solenoids 25a, 25b. A lift cylinder 8 is expanded and contracted similarly by an inclination detector 28 by detecting an inclination in a lateral direction of the carrier. As the carrier does not tilt more than a predetermined angle and a fixed posture is maintained even if a tractor is tilted through crossing over a footpath between rice fields, dropping of carrying goods disappears. |
