Raising
Equipment Damage Risk:
Raise the implement for folding and unfolding. If lowered,
inside wing disks and sweeps drag or dig sideways during fold/
unfold, and damage is likely.
Equipment Damage Risk:
Always raise the implement for tight turns and reverse/backing
operations. Backing with implement lowered causes implement
plugging and damage to implement ground engaging compo-
nents. Tight turns with implement lowered may damage ground
engaging implement components. The following steps presume
an implement lowered and unfolded for working a field. Follow
the detailed instructions in steps 21 through 24, beginning on
this page, until familiar with operation.
Equipment 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 Discovator. To reduce oil heating
and system wear, Do Not Set for Continuous Mode.
21. Make sure all persons are safely clear of implement
sections and out of danger zones.
22. Activate dedicated Lift circuit (normally Extend).
Refer to Figure 23
23. Extend cylinders until all sections are raised. Hold for
a few seconds to re-phase cylinders.
24. Set circuit to Neutral to temporarily hold sections at
raised.
Refer to Figure 24
Note: Transport locks are provided to hold a fold/unfold
implement at fully raised position for transport,
maintenance, or storage.
