The Seeder Hitch is equipped with a hydraulic lift system
to raise and lower the unit from transport to planting
position.

WARNING
Figure 4-8: Hydraulic Leak Detection
1. The hydraulic lift system contains cylinders plumbed
together.
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/unfolding for clearance of the wing fold lock
arms.
3. Before planting slowly raise the front hitch until the
seeder is level front-to-rear. The weight of the seeder
on the main lift will allow the front hitch to raise first.
4. The main lift is equipped with an automatic transport
lock, that engages when the units is folded and fully
raised. Verify that the locks are engaged before
attempting to adjust, service, or work beneath the
raised Seeder Hitch. The telescoping hitch is
secured by a locking pin (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 4-8.) Keep all components (cylinders,
hoses, fittings, etc.) in good repair.
