ADJUSTEMNT OF TOE-IN WITH TRACTORS EQUIPPED WITH A FRONT
DRIVING AXLE
Note: The tractors are equipped standardly with hydrostatic steering.
− Set the wheels symmetrically with the longitudinal axis of the tractor.
− As shown on fig. E503, measure at the front end in horizontal axis the distance be-
tween the rims. Mark the point of measurement.
− Drive on with the tractor so that the marked points are in horizontal plane of the
wheels axis on the back (turning by 180°) and repeated measurement of the dis-
tance between the marked points.
− Release the lock nuts of ball joint heads (2) of steering connecting rods at the hy-
draulic cylinder.
− Adjust toe-in of wheels by turning the ball joint shank (3). Perform adjustment of
both joints symmetrically to preserve the same locks of wheels to both sides (carry
out measurement on sides of the rims).
− Tighten lock nuts of ball joint heads (2) by a torque 122 to 136N. The upper sur-
faces of the heads (1) shall be parallel.

other holes) and to the desired height (by
relocation of the screws “b“ to other
holes) according to the desired wheel
treads and type of the tyres used.
