Install Ladder Mounts
Where to place the top ladder mount depends on the drill
configuration.
If the drill has the Small Seeds Box installed (or will be),
the outer rear hole of the mount is the second row from
the rear edge of the walkboard (see Figure 3 on page 3).
If Small Seeds is not installed, the corner mount hole is
the third row from the rear edge (see Figure 4 on
page 3).
Regardless of drill configuration, the outer rear hole of
the top mount the second row in from the end of the
walkboard.
