Be extremely cautious when driving the tractor
on a slope and rough terrain.
Observe the following precautions.
●
Before driving the tractor on a slope or a
rough terrain, engage the 4-wheel drive for the
following purposes:
• to increase traction
• to greatly assists in climbing steep slopes
• to improve braking power on sloped, frozen,
wet or graveled surfaces
• always be aware that the danger of tipping
over is still present
● Add weight to the tractor as necessary.
●
Drive at a lower speed to prevent skidding and
loss of steering control.
●
Keep away from slopes steeper than 15
degrees.
●
Avoid parking the tractor perpendicular to the
slope.
●
Avoid turning or changing travel directions on
a slope.
●
Before approaching a slope, select an
appropriate speed setting.
●
Make sure to travel at a lower speed when on
a slope.
●
Avoid shifting the range shift lever while
traveling on a slope. The preceding action can
make the tractor uncontrollable and suddenly
roll down the hill.
●
Do not move the range shift lever in N
(neutral) position when on the slope:
• the preceding action can make the tractor
uncontrollable and suddenly roll down the
hill
● Sudden operating the tractor on an uphill
slope can cause the front wheels to lift off the
ground and result in an extremely dangerous
situation.
● To prevent the preceding danger:
• run the engine at a lower speed
• slowly start the tractor
! WARNING
●
Avoid parking the tractor perpendicular to a
slope.
• if parking on a slope is unavoidable, chock
all the tires safely and securely and engage
the parking brake securely, for details, see
"6. Lock and Set the Parking Brake" on page
7-3
●
On a slope, the tractor is unstable and more
prone to severe injury or even death. Always
be alert.
●
Avoid traveling backward, up and down on a
slope to prevent tipping over.
●
Keep away from ditch or deep mud to avoid
the risk of the tractor tipping over.
●
Always drive slowly on any slope. Avoid
under any circumstances sudden change of
speeds or directions.
●
For increased stability of the tractor on slope:
• follow the instructions for proper weighting
• for details, see "Chapter 12. TIRES, WHEELS
AND WEIGHTS" on page 12-1
