Weight Transfer Adjustment
Weight Transfer Safety Information
Crushing and High Pressure Fluid Hazards:
This adjustment requires working near the unfolded and
lowered applicator with the hydraulic system active. Assign
two people to this task, one in the tractor, ready to shut down
on hand signal from adjuster or any unplanned event.
High Pressure Fluid Hazard:
Escaping fluid under pressure can penetrate the skin causing
serious injury. Use a piece of paper or cardboard, NOT BODY
PARTS, to check for suspected leaks. Wear protective gloves
and safety glasses or goggles when working with hydraulic
systems. If an accident occurs, seek immediate medical
attention from a physician familiar with this type of injury.
Crushing Hazard:
Keep body parts clear of wings, row cleaners and coulters
while adjusting. Keep all bystanders well away. You will be
seriously injured or killed if you are caught between lowering
row applicators and ground.
Falling Hazard - Tires Not a Step:
Do not use tires as steps or platforms. At some transfer
settings, cylinders can raise lift-assist wheels sufficiently for
them to spin. Gauge wheels can also be in light or no ground
contact when the weight-transfer system is not active.
Weight Transfer System
Refer to Figure 65 and Figure 66 on page 93
Inner wing fold cylinders can extend, during field
operation, to push the wings down using
mainframe/center weight. Weight transfer is enabled by:
1. Set the FOLD / FIELD switch to FIELD.
2. Adjust the weight transfer valve .
The fold/lift circuit is set to continuous flow (in unfold
mode) to maintain the active weight transfer. This system
is designed for use with tractors having closed center
hydraulics. It is incompatible with open center systems.
Note: Do not set or adjust the weight transfer system if
the outer wings are not level with the inner wings at
unfold. Do not use the weight transfer system to
compensate for unfold stop adjustment issues.
See “Unfold Stop Adjustment” on page 134.
