51. y with all local state and federal laws It is important that you inspect the area where you will be cutting and clear it of safety hazards and foreign objects either before or after you arrive at the cutting site Never assume the area is clear Cut only in areas you are familiar with and are free of debris and unseen objects Extremely tall grass should be cut twice to detect potential hazards In the event you do strike an object stop the cutter and tractor immediately to inspect and make necessary repairs to the cutter before resuming operation It really pays to inspect a new area and to develop a safe plan before cutting You will need to maintain 540 rom PTO speed and 2 to 5 mph ground speed to produce a clean cut Make a tractor gear and range selection that will enable you to maintain these speed combinations Generally the quality of cut is better at lower ground speeds Dense ground cover will create the need to slow down even more In certain conditions tractor tires will roll grass down resulting in an uneven cut when the grass fails to rebound Should this happens you may try reversing the direction of cut and or double cut to achieve the desired finish Avoid very low cutting heights especially on extremely uneven terrain Always cut downward on slopes and avoid crossing the face of steep slopes Avoid sharp drops and cross diagonally through dips to prevent hanging up the tractor and cutter Slow down in turns Remember to look
