FIELD OPERATION
PRE-OPERATION CHECK LIST:
Use this checklist each time you operate the 3800 Toolbar in the field. It will help you
obtain satisfactory field operation quickly.
1. Tractor sway blocks in upper position.
2. Center link adjusted for level frame in field operation.
3. Tractor lift links set in lateral float.
4. Hitch pins fastened and correct spacers used.
5. Quick couplers latched.
6. Adequate ballast added to front of tractor.
MAIN FRAME HEIGHT:
Without gauge wheels, set the tractor rockshaft control lever to obtain the desired frame
height.
With frame gauge wheels, put the rockshaft control lever all the way forward to lock “it” in
the float position, which will enable the frame gauge wheels to maintain the frame at a
uniform height from the ground.
LEVELING MAIN FRAME
Adjust lift links and center link as necessary to make frame level and perpendicular to the
ground.
Before activating/folding hinge check for obstructions, especially check gauge wheel
positions to ascertain proper tractor and cab clearance.
NOTE: If gauge wheels are to be used, make leveling adjustments after gauge wheels
are installed.
CLOSED CENTER HYDRAULIC SYSTEM
Wing fold hydraulic valve must be in float position to allow the wings to “flex” up and
down while operating in the field.
Wing fold hydraulic valve must be in neutral position to hold the wings “rigid” while
operating in the field.
CAUTION: ALWAYS FOLLOW ALL STATE, FEDERAL, AND LOCAL LAWS
WHEN TRANSPORTING 3800 TOOLBAR ON PUBLIC ROADS.
