SOLUTION
Adjust depth/rephase coulter gang
(See "Hydraulic Coulter
cylinders
Gang Lift System" on
page 4-6.)
(See "Leveling
Level unit front to rear
(Front-to-Rear)" on page 4-7.)
Reduce coulter depth.
Check inflation.
(See "Leveling
Adjust unit to be level
(Front-to-Rear)" on page 4-7.)
Adjust depth stop and raise implement.
Adjust unit to be level.
(See "Leveling
Level machine
(Front-to-Rear)" on page 4-7.)
Adjust coulter depth
See Figures 2-1
Install shovels (
2-16
.)
(See "Leveling
Level unit front to rear
(Front-to-Rear)" on page 4-7.)
Reduce depth
Install new points
Install seals with the lips pointing outward
away from the hub.
Fully extend cylinders and hold hydraulic
lever until all cylinders are fully
extended.
Wing cylinders are smaller diameter than
center cylinders. Reinstall cylinders
properly.
Check hose routing
Repair valve
Raise unit.
Wait until conditions more favorable.
Raise implement or wait until conditions
are more favorable
Replace bearing
Retighten gang shafts to 1200-1500 ft.-lbs.
If gangs have ran loose, gangs may
require disassembly to remove soil to
properly torque gang shafts. Replace
any worn components, shafts/spools,
etc.
