WORKING VEHICLE
Document Type and Number:
Japanese Patent JPH09109635
Kind Code:
A
Abstract:

To maintain good straight advancing performance as well as to decrease peak steering force and to eliminate a turning feeling and a climbing feeling by setting the caster angle of a steeling wheel on the front side in relation to the advancing direction is set to the minimum in a working vehicle to which a working machine is to be mounted.

In a working vehicle such as a tractor, a front weight 5 and a handle post 6 are arranged on the front part of a vehicle body frame 2, and a working machine such as a rotary cultivator is mounted on the rear part of it. The working vehicle is provided with the caster angle θ, namely, the angle formed by an axis L1 passing a king pin 42 in relation to a vertical line L0 passing an axle of a front wheel 3. In this case, the caster angle θis set to the minimum by being arranged rearward from the ground contact point G of the front wheel 3. The caster angle θ is specified in the range of -0.5° to -2°, preferably, it is set to -1.0°. Therefore, steering force, particularly, peak steering force is reduced, a turning feeling and a climbing feeling are eliminated, and good straight advancing performance is maintained.
