Note: The tractors are equipped with hydrostatic steering as standard.

fig. E503, the distance between the rims. Mark the place of measurement.
 Drive the tractor to move the marked places to the horizontal plane of the wheel
axes at the back (turning by 180°) and measure the distance between the marked
places again.
 Release the locking nuts of the heads of the ball screws (2) of connecting rods of
the steering at the hydraulic cylinder.
 Adjust the toe-in value by turning the shank of the ball screw (3). Perform the ad-
justment of both the joints symmetrically to maintain the same turning radius at
both the sides (perform the measurement at the rim sides).
 Tighten the locking nuts of the heads of the ball screws (2) with the torque of 122 -
