     Be observant of bridge loading ratings. Do not cross bridges rated lower than the gross weight at which you are operating.  Watch for obstructions overhead and to the side while transporting.  Always operate equipment in a position to provide maximum visibility at all times.

    OPERATING SUGGESTIONS There are some important points to remember in order to obtain the best possible results from your McFarlane harrow.  To maximize the harrow’s performance, it should be towed at speeds ranging from six to nine (6 - 9) mph. This keeps the field debris moving through the harrow sections and avoids clogging.

    ASSEMBLY SUGGESTIONS  You will find the machine is easier to assemble if the set-up instructions are followed in the order given in the manual.  Before beginning, sort the various bolt bags, hardware bags and hydraulic bags according to what part of the unit that is being setup.
