3.4 Adjusting / locking the tow-bar

3.4.1 Adjusting the tow-bar
The two stop bushes (1) on the tow-bar element can be adjusted
to any position in order to achieve the best working height on the
tow-bar grip.
3.4.2 Locking the tow-bar
The handle can be fixed in upright (2) or horizontal (3) position.
Using the lock provides with tow-bar leverage onto the machine,
thus assisting you under difficult ground conditions. This applies
in particular if the machine gets stuck.
The tow-bar lock makes it easier to handle the machine when
loading it.
To prevent deflection, the tow-bar must not be
locked during normal operation.
