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 little or no vertical travel with the operator
in the seat. 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 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 suspension seat
(for example fitting parts which are not original
GRAMMER parts) it may no longer meet the safety
standards 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 (Seat Manufacturer).
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.
CAUTION: Before the tractor is used, the safety
switch must be checked for proper function. The
operation of the switch is checked by having the op-
erator lift off the seat with the tractor moving forward
and/or the blades engaged -- this action should
cause the machine to stop. If a malfunction is de-
tected the tractor must not be driven, it should be re-
paired or replaced before operating the mower.
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 injury to the operator and/
or damages to the seat, the setting for the driver’s
weight must be checked and adjusted as necessary
before the mower is driven.
When the minimum/maximum weight adjustment
has been reached, you will notice an empty move-
ment in the handle.
When you have set the weight, fold the handle com-
pletely into the locking position.
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.
