SAFETY PRINCIPLES OF WORKING
WITH THE THREE-POINT HITCH
Persons that are not authorized to work
with the attached implement must not
stand between the tractor and the
hitched machine (implement) - (A). Do
not park the tractor with an attached
implement in the lifted position (B). Dur-
ing a drive without an implement the
lower draw-bars (5) must be connected
with springs and the upper draw-bar (1)
must be inserted into the spring sus-
pension! During transport of imple-
ments the limiting draw-bars (4) of the
lower draw-bars must be adjusted in
such a way to avoid unwanted lateral
movement of the implement!
