Raising Planter
Refer to Figure 24
1.
If the planter has hydraulic hitch, set the Lift/Hitch
switch
to LIFT.
Note: If the planter has the standard 3-point hitch, this
switch has no function. The hydraulic circuit is al-
ways in Lift (Raise/Lower) mode.
2. Move the cab lever to Extend the circuit for Lift/Hitch.
Machine Damage Risk:
On tractors with electronic timer controls for hydraulic cir-
cuits, 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
Refer to Figure 25
1.
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
page 29.
2. If equipped with hydraulic hitch, set the Lift/Hitch
switch
to LIFT. On 3-point hitch, this switch has no
function and the circuit is in Lift mode at all times.
3. Move the cab lever to Retract the circuit for Lift/Hitch.
When fully lowered, return lever to neutral.
Machine Damage Risk:
Do not lower planter while folded unless cylinder lock chan-
nels are installed on cylinders. Without lock channels, lower-
ing when folded causes the front center transport wheels to
contact the inside wing row units. Damage WILL occur.
Machine Damage Risk:
Never lower planter while partially unfolded. Wing row units
can strike main transport wheels.
