1.Using the tractor, raise the mower off the ground and place supports underneath of it, so that it will not drift downwards while making adjustments or mainte- nance.
2.While supporting the wheel and yoke assembly off the ground, remove the snapper pin from the top of the gauge wheel spindle. Position the supplied spacers as required for achieving the desired cutting height.
3.Make sure all four wheels are adjusted the same.
