Purge Hydraulic System
DANGER
!
To avoid serious injury or death:
•
Never remove or install a hydraulic cylinder with
hydraulics to the cylinders under pressure. The seeder will
drop suddenly. Also, air trapped in a new or repaired
cylinder can drop the seeder suddenly when raising and
lowering the unit. Either situation can damage to the seeder
and cause serious bodily injury or death.
•
Do not use a park jack to support the seeder during purging
operations. The seeder can fall while purging the hydraulic
system. Instead, hook seeder to a tractor drawbar to help
stabilize the unit while purging the hydraulic system.
•
Make sure the implement is lowered to the ground and all
hydraulic pressure is relieved before hooking-up or
disconnecting any hydraulic lines, fittings, or cylinders.
1.
Hook seeder to the tractor drawbar. Refer to steps 1-
13 under
“Hook-up Pull-Type Seeder”
on page 24.
Do not attach hydraulic hoses to the tractor duplex at
this time.
2.
Remove park jack and store it on the seeder frame.
Refer to
“Store Park Jack”
on page 25.
3.
With barrel end of all three hydraulic cylinders pinned
to their respective mounting lugs and all hydraulic
fittings are tight, unpin cylinder rods from their
mounting lugs.
4.
Tip rod end of all three hydraulic cylinders up as
much as possible and in some fashion hold cylinders
in this position without restricting rod movement.
5.
Attach hydraulic hoses to the tractor duplex outlet
with float capabilities.
6.
With tractor started, engage hydraulics until the
hydraulic cylinder at the front of the seeder is fully
extended.
7.
Disengage hydraulics, and wait one minute. This will
allow any trapped air to migrate toward the
re-phasing port.
8.
Repeat steps 6 & 7 for each of the two remaining
hydraulic cylinders.
9.
Engage hydraulics again and hold engaged for two
full minutes.
IMPORTANT:
Be sure tractor reservoir is filled
properly before operating hydraulic cylinders. If
tractor reservoir is low on hydraulic fluid, there is a
chance of drawing air into the system causing jerky
or uneven cylinder movements.
IMPORTANT:
Attach hydraulic hoses only to tractor
hydraulics with float capabilities.
Tractor hydraulics
for the seeder must be locked in float position
while lowering the seeder and while seeding,
otherwise the seeder can be damaged.
10. After two minutes have passed, cycle hydraulic
cylinders by fully retracting and extending them. End
with cylinder rods fully extended.
11. Shut tractor engine off and remove switch key.
12. Remove supports holding cylinder rods in the tipped
up position.
13. Return to the tractor and retract cylinders slowly until
cylinder rod clevises align with mounting lugs.
14. Shut tractor engine off and remove switch key.
15. Pin cylinder rods to their respective mounting lugs.
16. When all three rod ends are pinned securely, restart
tractor and engage hydraulics to lift seeder until
cylinder rods are full extended. Hold tractor lever in
the engaged position for one minute.
17. With cylinders fully extended, shut tractor engine off
and remove switch key.
18. Check and refill tractor hydraulic reservoir if needed.
