PURPOSE:To stabilize a tractor, by providing a front and a rear fitting portions on at least the front and rear sections of the bottom of the tractor to lower its center of gravity. CONSTITUTION:Front fitting portions 8, 8' are attached to the supports 3, 3' of the front fitting portions 1, 1' of a tractor 2 by pins 4 as a weight 7 is supported by a stand 11. The tractor 2 is then slowly moved forward as the rear of the weight 7 is on the ground. At that time, chains 15 are trodden by the wheels of the tractor so that the stand 11 is fixed in a position and the weight 7 is gradually elevated. The rear of the weight 7 is then attached to the rear fitting portion 5 of the tractor 2 by a pin 6, thus completing the mounting of the weight on the tractor. |
