Walkboard and Ladder Operations
Refer to Figure 34, 35 and 36
The walkboard provides a convenient platform for hopper
inspection, and bag- or auger-loading of seed into the
hopper. The walkboard also swings open for seed con-
tainer exchanges, and stores a row-unit tool.
Falling Hazards:
Check that the walkboard pin
is in place before climbing.
Check that both railing pins are fully seated before leaning
on rear center railing. There is no center railing on the seed
side of the walkboard. If latch pins are not seated in swing-
down railing segment, it could swing to the rear. If the walk-
board or railing swing open you could fall, resulting in serious
injury or death.
▲ Always face ladder when climbing.
The walkboard has five key features:
1. Walkboard pin - keeps walkboard closed.
With left end of walkboard fully forward in channel at
ladder top, insert pin, and secure lowered end of pin
with wire bail.
2. Walkboard keeper - holds walkboard open when
hooked into...
3. Keeper keyhole.
Swing walkboard to near fully open. Engage wide
end of keeper in narrow slot of keyhole.
4. Swing-down railing - eases auger tube access.
Pull wire cross-pin towards implement center-line. If
not pulling both at once, rotate pin one quarter turn
and release into shallow detents. Swing railing sec-
tion down. When returning railing to normal position,
release both pins into deeper detents, and check
that both pins are fully seated.
5. Walkboard tool - adjusts opener down-force cam.
