SMOOTHING 3
NOTICE
Avoid smoothing on rocky or stony ground. It can damage the blade.
To finish the ground to a flat surface after digging or leveling,
put a full load of soil in front of the blade and operate the blade
up and down in small movements while traveling forward.
Finally, place the blade at FLOAT and travel at low speed in
reverse while pulling the blade over the ground surface. Before
doing this, hold the lever by hand at the FLOAT position for at
least 1 second to make sure that it stays in position. To prevent
damage to the blade, be careful not to travel over any stones or
rocks.
CUTTING INTO HARD OR FROZEN GROUND OR DITCHING 3
For digging and ditch excavation of hard or frozen ground, tilt
the blade. Even hard ground can be dug effectively by a tilted
or angled blade.
FELLING TREES, REMOVING STUMPS 3
NOTICE
Do not uproot trees or stumps or fell trees by angling or tilting the blade.
For trees with a diameter of 10 to 30 cm, raise the blade high
and push 2 or 3 times to fell the tree.
Next, travel in reverse, and dig the corner of the blade into the
ground to cut and dig up the roots.
When doing this, never hit the tree at high speed or apply
shock to fell the tree.
