efficiency are all affected by weight distribution, trailed or
mounted implements, additional ballast and driving
conditions. It is therefore of great importance that the
operator exercises caution in every given situation.
Groundspeed must be adapted to ground conditions as
well as to roads and paths. Always avoid abrupt change s
of direction.
Be particularly cautious when turning corners, paying
attention to machine overhang, length, height and
weight.
Never use a narrow track tractor on very uneven or
steeply sloping ground.
