Suspension Seat (MTL and MTLEFI)
A fully adjustable suspension seat is standard on
Models MTL and MTLEFI. This seat is adjustable
for back pitch, weight, lumbar support and armrest
inclination. Proper adjustment for each operator is
essential to safe operation and operator comfort.
Read operating instructions in full before you use
the seat.
NOTE: Driver seats that have been adjusted incor-
rectly have a smaller swinging range. To prevent
damage to the driver’s back and to the seat, the seat
must be adjusted for the driver’s weight before use
and before every change of driver. To prevent in-
jury, no objects should be placed within the
swinging range of the driver seat.
To prevent injury, no objects should be placed
within the moving area of the driver seat.
Adjustments must not be made while driving.
If you make any changes to the standard seat (for
example fitting parts which are not original GRAM-
MER parts) it may no longer meet the safety stan-
dards to which it is tested. Functions may be
impaired, threatening your safety. For this reason,
any change in design of the seat must be ap-
proved by GRAMMER.
IMPORTANT: Fasteners must be checked regu-
larly for tightness. If the seat wobbles there may
be loose bolts or other faults.
If you note that the seat does not function correctly
(for example a defective seat suspension; improper
curving of the lumbar support or damaged bellows),
contact your Walker Dealer immediately to ar-
range for repairs to be carried out. If you fail to do
so, your health may be affected and the risk of ac-
cident increased.
IMPORTANT: Before the tractor is used, the safety
switch must be checked for proper function. If a
malfunction is detected the tractor must not be driv-
en, it should be repaired or replaced before operat-
ing the mower.
If you take off the weight from the seat while driving,
this will cause the machine to stop.
IMPORTANT: Do not indent the bellows while there
is load on the driver’s seat.
For armrest inclination adjustment, the inclina-
tion of the armrests can be modified by turning the
adjustment knob. Refer to Figure 1.
Turning the knob to the right lifts the armrest in front,
turning it to the left, lowers it in front.
For weight adjustment, the weight of the respec-
tive driver must be set while sitting on the seat. Fold
out the weight adjustment handle completely, hold it
at the front and move it upwards or downwards (10
movements from minimum to maximum).
Before every new movement, bring the handle back
to the starting position (audible locking sound). The
driver’s weight has been set correctly, when the ar-
row is in the middle of the viewing window. Refer to
Figure 2.
IMPORTANT: To prevent damage to the health and
material, the setting for the driver’s weight must be
checked and adjusted as necessary before the
mower is driven.
When the minimum/maximum has been reached,
you can notice an empty movement in the handle.
When you have set the weight, fold the handle com-
pletely into the locking.
CAUTION
To eliminate any risk of accident, the set-
tings must be checked to ensure they are
correctly engaged before the mower is
driven.
CAUTION
Except for the driver’s weight during nor-
mal use, no loads must be placed on
seats with a built-in switch detecting seat
occupation, as the vehicle may otherwise
start to move by itself.
