Cornering
When operating the machine, if an extreme change of direction is required, for example a 90° turn; disengage
the PTO, lift the machine, make the turn and proceed to restart the machine and continue with mowing.
Perform turns with the tractor and mower at slow speeds to
determine how the tractor handles with the attached mower.
Determine the safe speed to maintain proper control of the
tractor when making turns. When turning with a mounted
implement, the overall working length of the unit is
increased. Allow additional clearance for the mower when
turning.
To avoid overturns, drive the tractor with care and at safe
speeds, especially when operating over rough ground,
crossing ditches or slopes, and turning corners.
Use extreme caution when operating on steep slopes.
Keep the tractor in a low gear when going downhill.
Do
not
coast or free wheel downhill.

– Tractor Stability
It important to ensure that the tractor lower link chains are tight when the machine is fitted. This will limit machine
sway from left to right and make it more stable and safe whilst at work or being transported.
4.9.5
Crossing Ditches & Steep Inclines
When confronted with an incline or ditch,
do not approach
from an angle which is perpendicular or straight on
. When
crossing such terrain, the implement should be fully lowered
for a lower centre of gravity and added stability.
Inclines and ditches
should be approached along a line which
is at an angle
as shown in Figure 4.21. This type of path will
reduce wear on the driveline of the tractor and/or tractor. If the
gradient is so steep that such an approach increases the
possibility of a tractor roll-over, select an alternate crossing path.
When operating the tractor and machine across slopes and
inclines, through ditches, and other uneven terrain conditions, it
is important to maintain sufficient deck to ground clearance.
Blade contact with the ground may cause soil, rocks and other
debris to be thrown out from under the mower resulting in
possible injury and/or property damage. Ground contact also
produces a severe shock load on the mower drive and to the
mower blades resulting in possible damage and premature wear.
