SAFETY PRINCIPLES WHEN WOR-
KING WITH A THREE-POINT LINKAGE
Persons who are not charged
with work with auxiliary device of
a tractor must not stand between
a tractor and connected machin-
ery (tools) - (A).
Do not park tractor with mounted
tools in a lifted position (B).
When driving without tools it is
necessary to connect lower draw
bars (5) by springs and upper
draw bars (1) to be placed to a
flexible linkage! When transport-
ing tools it is necessary to adjust
limiting draw bars (4) of lower
draw bars so that there would be
no unwanted side movement of
tools!
