This is also the basic position for defining the direction in connection
with which:
- rh (rotation) = clockwise rotation
- lh (rotation) = counter or anti-clockwise rotation
Rotation around a vertical axis is defined when looking from top to
bottom.
Rotation around a horizontal axis almost perpendicular to the direction
of travel is defined when looking from the left to the right.
Rotation of bolts, nuts, hand cranks, etcetera is defined when looking
from the position of operation.
Units of measurement are given both in Imperial/US and international
metric units; the metric value shall be decisive.

the corresponding position!
•Always fit front weights to the fixing points provided for that
purpose.
•Adhere to maximum permissible axle loads, total weights and
transport dimensions!
•Install and check transport equipment, e.g. lighting, warning
devices, guards!
•For road transport bring machine in a transport position and secure
it!
•Never leave the operator's seat during operation or transport.
•Moving behaviour, steerability and braking performance are
influenced by mounted implements and ballast weight! Ensure
sufficient braking effect and safe manageability!
•Always adapt the speed to the local conditions! When making short
turns note the larger radius because of increased width and/or
length of the combination as well as mass and inertia changes due
to the other center of gravity position!
•Do not operate a machine unless all protection is installed and in
functional position!
•Never stay or allow anyone to stay within the operating area!
•Never stay or allow anyone to stay within the turning and slewing
area!
•Before leaving the tractor lower the machine onto the ground,
apply the parking brake, shut down the engine and remove the
ignition key!
•Allow nobody to stay between tractor and machine unless the
tractor is prevented from inadvertent rolling away by applied
parking brake and or placed chocks!
•Before (un)hitching the machine on the three-point linkage set the
controls in a position that prevents from inadvertent lifting/lowering!
•Ensure hitching category of machine corresponds to tractor: adapt
if required!
•Keep clear of three-point linkage area: danger of crushing and
scissoring!
•Do not stand between tractor and machine when handling the
external three-point linkage controls!
•Always use stabilizers or check chains to prevent sideways
movement of the machine, especially during transport!
•During road transport the three-point linkage control lever must be
secured against lowering!
•The protection of the machine prevents from penetrating into
