Title: Pneumatic tire for reaping machine
Inventor: EOMO SAKAE
IPC: B60C11/11
Filed: 1991-12-26
Abstract: PURPOSE:To display a strong tractive force and to prevent side skid by forming a lag with a bridge extending roughly in the circumferential direction to connect a side part inclined in a range of a specified angle against the direction of the rotation axis of a tire, a central part and two other parts which are less inclined than the side part with each other. CONSTITUTION:Lags 2 extending from both sides of a tread 1 to the center of the tread 1 inclined in a herringbone pattern are arranged with specified intervals. This side part 4 constituting these lags 2 is inclined in a range of 20 deg.-45 deg. against the direction of the rotation axis of a tire, and this side part is cut into a part of earth well, and a tractive force is displayed. The tractive force is more strongly displayed as this side part 4 is well engaged with a stump by lessening inclination of its central part 5 rather than inclination of the side part 4. Furthermore, it is possible to prevent side slip of a reaping machine body and to restrain rolling by forming a bridge 6 extending roughly in the circumferential direction to connect the side part 4 and the central part 5 with each other.
