Toolbar Height and Orientation
WARNING
!
Never allow riders on the tractor or implement. Failure
to follow this information could result in death or serious
injury.
Riders hinder operator visibility and can be thrown from
the implement and/or be struck by foreign objects
resulting in injury or death.
1. Connect the implement hitch to the tractor. See
“Implement-to-Tractor Connection” on page 4-3.
DANGER
!
Avoid crushing. Failure to follow this information will
result in death or serious injury. Make sure all personnel
are clear of the implement before lowering.
2. Lower the implement to the ground, place the tractor
in park, turn off the engine, and remove the key.
NOTE: When setting toolbar height and orientation,
disregard row unit performance. Toolbar height
and orientation must be established prior to tooling
adjustment.
The top and bottom of the toolbar (3 and 2) must operate
parallel with the ground surface. Adjustment of the tractor
three-point hitch, lift assist wheels, and/or toolbar gauge
wheels (if equipped) will allow the toolbar to operate
parallel with the ground surface.
The bottom of the toolbar should operate at an
approximate height of 30-32 in (76-81 cm) (1) above the
ground surface (4). Use the tractor lower hitch stop, lift
assist wheels, and/or toolbar gauge wheels (if equipped)
to set desired toolbar height.
Have an assistant pull the tractor and implement slowly
forward in the field position as you view the end of the
toolbar from a safe distance. Observe toolbar height and
orientation while in operation. Make adjustments
accordingly until the top and bottom of the toolbar
operate parallel with the ground surface and the bottom
of the toolbar operates at an approximate height of 30-32
in (76-81 cm) above the ground surface.
For more information, see the toolbar’s operator manual.
After desired toolbar height and orientation is
established, set the tractor lower hitch stop, lift assist
wheels, and/or toolbar gauge wheels (if equipped).
NOTE: Larger implements may require lift assist wheels
and/or toolbar gauge wheels to support toolbar
weight. Lift assist wheels and/or toolbar gauge
wheels displace a portion of the toolbar weight to
allow maximum parallel linkage travel.
NOTE: Smaller implements may operate without lift assist
wheels and/or toolbar gauge wheels
(if equipped) .
The tractor hitch will bear a portion of the toolbar
weight by setting a lower hitch stop on the tractor
three-point hitch control.
Row Unit Depth
The depth band coulter assembly should allow the
toolbar to operate at the desired height and provide
consistent row unit tooling depth by governing soil
penetration.
Adjustable down pressure springs supply row unit down
pressure to assist with row unit soil penetration. Parallel
linkages, with the ability to travel vertically, allow row
units to operate independent of the toolbar. The depth
band, down pressure springs, and parallel linkages
should allow the toolbar to serve as a towing device,
allowing uniform tillage despite terrain variations. See
“Field Adjustments” on page 5-4.
For the toolbar to serve as a towing device, the ground
surface, toolbar, and linkage must generally operate
parallel to one another when in the field position. See
Figure 5-1 on page 5-3. In most field conditions, the
linkage will operate at a slight downward angle. See
Figure 5-2 on page 5-3.
