Operating Instructions

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 incorrectly 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.

CAUTION

To eliminate any risk of accident, the settings must be checked to ensure they are correctly engaged before the mower is driven.

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 approved by GRAMMER (Seat Manufacturer).

IMPORTANT: Fasteners must be checked regularly 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 arrange for repairs to be carried out. If you fail to do so, your health may be affected and the risk of accident 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 operator 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 detected the tractor must not be driven, it should be repaired or replaced before operating the mower.

CAUTION

Except for the driver’s weight during normal 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.

For armrest inclination adjustment, the inclination 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 respective 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 arrow 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 movement in the handle.

When you have set the weight, fold the handle completely into the locking position.
