Seat Adjustments
The seat and ground speed control levers should be
adjusted so that operator’s elbows are supported by the
arm rests when his/her hands are on the controls, and
the ground speed control levers can be moved through
their full range of motion without contacting the operator’s
legs.
Seat Position Adjustment
The seat can be adjusted forward and back. Move the
adjustment lever (A, Figure 11) towards the left hand side
of the machine, slide the seat to the desired position, and
release the lever.
