Emergency Moves Without Steering
To move the planter with a tractor lacking 3PYPA steer-
ing components, or to move a planter with a steering sys-
tem malfunction, the casters must be in Float. Steps
below describe methods for several situations.
Force Caster Float
Any of these configurations will float the casters.
1. Normal Caster Float
(for forward travel only - do not back up)
2. ECU-Disconnected Caster Float
(for forward travel only - do not back up)
3. Mechanical Float
(for forward travel only)
(APPLIES ONLY TO PLANTERS WITH s/n B1027J+)
Null4.aac:
a. Shut off tractor. Power-Beyond cannot be con-
nected with tractor running.
b. Make all normal hydraulic and electrical connec-
tions, including steering. Start tractor.
c. Set “STEER” switch on steering switch box OFF.
d. If casters do not float, try step 2.
a. Shut off tractor. Power-Beyond cannot be con-
nected with tractor running.
b. Make all normal hydraulic connections, including
steering (see page 17). Start tractor.
c. Make all normal electrical connections, EXCEPT
steering (see page 16).
a. Remove 1

in pin locking the caster weldment
and steering arm weldment together.
b. Make all normal hydraulic and electrical connec-
tions EXCEPT power beyond pressure line.
Equipment Damage Risk:
Make no planter moves of any kind with casters in hydraulic
lock. Damage to both planter and tractor is likely. Take all
steps necessary on this page to enter Float state.
Equipment Damage Risk:
Make only careful forward moves with casters in Float. With
options 1- 3, do not make reverse moves. The casters immedi-
ately swivel to a hard turn state, usually opposite to any trac-
tor turn. Damage to planter and tractor is likely.
