the lever base should be pointing towards the front as
shown in Figure 3.
1. Install the ground speed control levers onto the
control lever base (C) using the 5/16-18 x 3/4" bolts,
5/16" lock washers and 5/16" flat washers (D, E & F).
Prior to tightening the bolts, align the handles with
each other.

Ground Speed Control Lever Adjustment
The ground speed control levers can be adjusted in three
ways. The alignment of the control levers, the height of
the levers, and the placement of the levers (how close
the ends are to one another) can be adjusted.
HANDLE ALIGNMENT ADJUSTMENT
1. Loosen the mounting hardware (D, E & F) and pivot
the ground speed control lever(s) (A & B) forward or
back to align with one another.
2. Once alignment is achieved, re-tighten the mounting
hardware.
HANDLE HEIGHT ADJUSTMENT
1. Remove the mounting hardware.
2. Reposition the ground speed control lever either up
or down from its original position and reinstall the
mounting hardware.
