gradually increase speed as conditions permit.
• Do not attempt to use dethatcher in eld mowing.
• For best results, use a "criss-cross" pattern on your lawn.
• Vary vehicle speed to determine best speed.
• The front and rear tines should be kept level.
• Stop vehicle and lift dethatcher to transport position
when making sharp turns.
