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.

STORAGE

• Always store in a dry area, and coat spring tines with light oil when not in use.

TO REMOVE DETHATCHER FROM TRACTOR (Refer to gure 17).

• Lower dethatcher to ground.

• Remove 3/32" (small) hairpin cotter and 3/8" x 3/4"

clevis pin from lift handle. Remove handle from handle lift bracket.
