PURPOSE:To know the tilt limit angle in advance even upon variation of the center of gravity of tractor by detecting the elevating position and the weight of working machine thereby calculating the accurate tilt limit angle of tractor. CONSTITUTION:A working machine is fixed to a tractor elevatably through a lift arm 7. Means 24 for detecting the inclination angle of tractor, means 15 for detecting the rotary angle of lift arm 7 and means 29 for detecting the weight of working machine are provided onto the chassis of tractor. The center of gravity of tractor is calculated in a center of gravity position operating unit 30 on the basis of a signal from respective detecting means thus to calculate the tilt limit and of tractor on the basis of said center of gravity position. Consequently, the operator can confirm the tilt limit angle in advance even upon variation of the center of gravity of tractor resulting in prevention of tilting of tractor. |
