WARNING
Figure 4-7: Hydraulic Leak Detection
1.
The hydraulic lift system contains cylinders plumbed
together.
2.
Before transporting make sure both lift cylinders and
hitch cylinders are fully extended for maximum
transport height.
3.
The Grain Drill can have both positive and negative
hitch weight. Attach the drill to the tractor before
attempting to raise or lower the drill hydraulically.
4.
Field Operation
a.
Before starting field operation, fully raise the drill
and remove transports locks (See “Transport
Locks” on page 4-4.)
b.
Lower the drill completely when planting to
insure consistent depth.
c.
Raise the drill when making sharp turns to
prevent side load/damage to the openers.
d.
Never back up the Grain Drill with the openers in
the ground. This can plug and possibly damage
the openers. Always fully raise the drill before
backing.
e.
Fully raise the drill and install the transport locks
before transporting or working beneath the drill
(See “Transport Locks” on page 4-4.)
Escaping hydraulic fluid can cause serious
personnel injury. Relieve system pressure before
repairing, adjusting, or disconnecting. Wear
proper hand and eye protection when searching
for leaks. Use cardboard instead of hands (See
Figure 4-7.) Keep all components (cylinders,
hoses, fittings, etc.) in good repair.
