Raising Planter
Refer to Figure 24
1.
If the planter has hydraulic hitch, set the Lift/Hitch

Note: If the planter has the standard 3-point hitch, this
switch has no function. The hydraulic circuit is
always in Lift (Raise/Lower) mode.

Machine Damage Risk:
On tractors with electronic timer controls for hydraulic
circuits, lift timers must be set to no more than 2 seconds
longer than needed to fully raise planter.
Do Not Set for Continuous Mode.
For transport, maintenance or storage, install lift cylinder
locks. See “Lift Cylinder Lock-Up” on page 29.
Lowering Planter

If lift cylinder locks are installed, first fully raise the
planter, and remove the locks. See “Raising
Planter” on page 28 and “Lift Cylinder Lock-Up” on

3. Move the cab lever to Retract the circuit for Lift/Hitch.
When fully lowered, return lever to neutral.
Machine Damage Risk (Hydraulic Hitch Only):
Never lower planter while fully folded, if it is equipped with
the hydraulic tongue hitch, or machine damage can occur
unless a special procedure is followed (see page 29). A planter
with a 3-point hitch may be lowered while folded.
Machine Damage Risk:
Never lower planter while partially unfolded (with either
hitch). Wing row units can strike main transport wheels.
