Tractor Hydraulic Hook-Up
!
WARNING
Serious injury or death couldresult fromescaping high pressure
hydraulic fluid. Use paper or cardboard, NOT BODY PARTS, to
check for suspected leaks.
For pull-type seeders equipped with front or end wheels,
route all hydraulic hoses along the tongue and through
the hose loop on the front of the tongue as described in
the assembly instruction section. Connect the hoses to
the tractor remote outlets.
Bleeding Hydraulic System
The Front and End Wheel Pull-Type Seeders are
equipped with rephasing type lift hydraulic cylinders that
require a special procedure for bleeding air from the
hydraulic circuits. If your dealer has not already prepared
the cylinders for transport use, read the following
information carefully. The rephasing type cylinders will
not function properly if this procedure is not followed.
!
CAUTION
Do not crack hose fittings in order to bleed air from this system.
1. Put the tractor in park and activate its parking brake.
If the tractor does not have these features, block 2 or
3 of its wheels to positively prevent the tractor from
rolling during this bleeding operation.
2. Jack up and support the front of the seeder at a point
close to each wheel to take the weight off of the
cylinders. If the wheel cylinders have previously
been engaged, they may be used to assist in raising
the frame.
3. With the seeder blocked and supported, unpin both
ends of the cylinders. Remove and safely position
the cylinders so the base end of the cylinder is lower
than the rod end port. Also, make sure there is
enough room for the rods of each cylinder to fully
extend without contacting anything.
4. With the tractor at idle, hold the remote lever on to
put fluid into the lifting circuit. When the slave
cylinder has been completely extended, hold the
remote lever on for one minute.
NOTE: Check the hydraulic fluid in the tractor
reservoir and fill to the proper level before starting
this procedure. If the bleeding is performed with a
low reservoir supply, there is a chance of drawing air
into the system causing jerky or uneven cylinder
movements.
NOTE: In order to prevent trapped air pockets, the
port on the rod end must be higher than any other
part of the cylinder during the bleeding operation.
5. Retract the cylinder rods. Extend the rods again and
hold the remote lever on for one more minute.
Repeat this step two more times to completely bleed
the system.
6. Retract and reattach the hydraulic cylinders. If air is
trapped in either cylinder, the affected cylinder will
have a spongy, erratic movement and the seeder will
not raise evenly.
7. Add oil to the tractor’s hydraulic reservoir to fill it to
the proper level.
After the seeder is raised, a slight settling will occur due
to the action of the rephasing cylinders.
Operating Hydraulic Lift System
The lift cylinders may after a period of time get out of time
or phase. The effects of this can be seen when one wheel
of the seeder is higher than the other because its lift
cylinder is over retracted compared to the other lift
cylinder.
To rephase the cylinders, raise the seeder completely up
and hold the tractor hydraulic lever on for a few seconds
to give the cylinders time to rephase. This should be
done each time the seeder is raised. Momentarily
reversing the hydraulic lever immediately after rephasing
to allow the cylinders to retract about 1/2” will help in
maintaining a level seeder during transport.
Transporting
!
CAUTION
When traveling on public roads whether at night or during the
day, use accessory light and devices for adequate warning to
operators of other vehicles. Comply with all federal, state and
local laws.
1. Select a safe ground travel speed when transporting
from one area to another. When traveling on
roadways, transport in such a way that faster moving
vehicles may pass you safely.
2. Reduce tractor ground speed when turning. Leave
enough clearance so the seeder does not contact
obstacles such as buildings, trees or fences.
3. When traveling over rough or hilly terrain, shift tractor
to a lower gear.
Pull-Type, Front, or End Wheel Seeders
1. For Pull-Type Seeder with or without wheels, make
sure the seeder is securely attached to the tractor
draw bar and the hitch safety chain has been
securely attached.
NOTE: Understand that having the cylinders
become gradually out of time is different than having
air trapped in the system from improper bleeding.
Each condition is corrected differently.
