PROBLEM TO BE SOLVED: To solve problems in a working machine mounted in a tractor and conducting basic work and additional work by two or more working devices, in which torque is insufficient when driving the working devices only by ground wheel driving and slip resistance is inferior, and an increase of the number of ground-engaging wheels and a change to support wheel driving are employed for the resolution, however it is not sufficient.SOLUTION: A working machine is characterized by: providing support wheels 28L/28R with weights 22 driving a first drive shaft 34 of seeding devices 8L/8R by a first power take-off unit 7 for taking out power from a ground-engaging wheel 11 driving a second drive shaft 129 of a fertilizing unit 9 by a second power take-off unit 140 for taking out power from the support wheel 28L providing the second power take-off unit 140 with a first boss section 157 of an axle 138 of the support wheel 28L and an elastic link mechanism 152 for elastically connecting between second boss sections 160 of the second drive shaft 129 in any direction and disposing a fertilizer hopper 123 on the second drive shaft 129 at the position higher than the seeding devices 8L/8R, and in a side view, on the upward of weight tables 70L/70R.
