4-12.1 The hydraulic lift system contains cylin-
ders plumbed together.
4-12.2 The main lift cylinders and telescoping
hitch are connected together on the same
hydraulic circuit. Before transporting make
sure both lift cylinders and hitch cylinders are
fully extended for maximum transport height.
Fully lower both cylinders when folding/un-
folding for clearance of the wing fold lock
arms.
4-12.3 Before planting slowly raise the front
hitch until the drill is level front-to-rear. The
weight of the drill on the main lift will allow
the front hitch to raise first.
4-12.4 The main lift is equipped with an auto-
matic transport lock, that engages when the
units is folded and fully raised. Verify that the
locks are engaged before attempting to ad-
just, service, or work beneath the raised
grain drill. The telescoping hitch is secured
by a locking pin (See Section 4-4).
