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 32.

planter, and remove the locks. See “Raising
Planter” on page 29 and “Lift Cylinder Lock-Up” on
