Hydraulic Lift System
The Seeder is equipped with a Hydraulic Lift System to
raise and lower the unit in the field.
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 3-8.) Keep all components (cylinders,
hoses, fittings, etc.) in good repair.
Figure 3-8: Hydraulic Leak Detection
1. If the Hydraulic System is not filled with oil it should
be purged of air before transporting and field
operations. Carefully hitch the Seeder to the Tractor
and connect the Hydraulic Lift Hoses.
2. Disengage the Transport Locks. See Figure 3-7.
3. Check to make sure the Tractor Hydraulic Reservoir
is full of the manufacturer's recommended oil.
4. Slowly raise the machine until all Lift Cylinders are
fully extended. Lower and raise the unit to verify that
all Cylinders are working throughout the stroke. Fully
extend the Lift Cylinders and continue to hold the
lever until all Cylinder Rod movement stops.
Raise/Lower machine 5 times to purge air from the
system.
5. Do not loosen any Hoses or Fittings. Recheck
Tractor Reservoir to make sure it is within operating
limits.
6. Re-install Transport Locks. See Figure 3-5.
Lift Circuit approximate oil requirement: .4 gallons.

WARNING
Transmission Electric Clutch
IMPORTANT
At no time use high pressure water or air to clean the
Electric Clutch as damage could occur.
• The Electric Clutch
is controlled by a Toggle Switch
on the Clutch Switch Box that is mounted to the
Tractor.
•
The Electric Clutch
is disengaged when power (12
Volts) is applied. If there is a power failure or
electrical problem, the Seeder will continue to
operate, so the machine must be raised to stop
seeding.
• Seed Shafts will not rotate when the machine is
backed up.
• The
Clutch
Switch Box contains a 5 Amp Time-Delay
Fuse.
• The Electric Clutch must be disengaged (power
applied) when Seed Shafts are turned manually for
Calibration.
• Check Electric Clutch Operation. The Electric Clutch
will disengage when power is applied. (Clutch will
make a clicking sound). Set Seeder on the ground
and drive a short distance while turning Toggle
Switch to "Seed" and "No Seed". The Seed Shaft will
stop rotating when Toggle Switch is turned to "No
Seed" Position.
• Turn Toggle Switch to "Seed" Position when Seeder
is not used to shut off power to prevent possible
overheating of Clutch Coil.
