The optimum working depth varies with soil con-
ditions. The working depth is determined by how
hard the depth skid is pushed down during propul-
sion. Operate and test.
Drive 2-3 times in different directions for best re-
sults.
Never operate the machine in wet soil. Clumps of
earth are created that are then difficult to break-up.
Hard and dry soil requires an extra run, at right an-
gles to the first.
WARNING! Never overload a new ma-
chine. Drive carefully for the first 5
hours.
