To improve working capacity and operating accuracy of small mower-loader, especially by preventing off-tracking phenomenon, authors developed new steering method called dual steering, which is the combination of articulated frame steesing and rear wheel steering. The method to make the radii at inner front and rear wheels same by use of the dual steering was also developed and confirmed by experimental mower-loader equipping dual steering.
It was shown that the dual steering decreased steering torque when 4 wheels drive was chosen. The off-tacking area at the turning point caused by the dual steering was considerably narrower than by articulated steering. However, off-tacking phenomenon could not be exclued, when steering speed was fast.
