Shift 2-Point Hitch
Refer to Figure 77
The front tool bar of the forward sub-frame has stop keys
for the standard (pre-emergence) hitch position
and
for the side dress hitch position .
39. Loosen or remove the nuts at all four hitch
U-bolts.
40. Move each hitch to align the left edge of the bolt
plate with the left stop keys on the frame.
41. Tighten nuts to
3 ⁄
4
-10 Grade 5 torque specification.
Caster and Gauge Wheel Considerations
42. As needed, adjust the angle of casters to keep tires
between rows of post-emergence crops. See
page 62.
Note: Keep caster angles symmetrical. Great Plains
does not recommend angling both casters left to
mimic the hitch shift, as this has negligible benefit
afield. A both-left configuration could cause
problems when raised, as wheels would be to left of
machine center of gravity (particularly with optional
weights). This could result in tipping right in turns
and unbalanced weight transfer.
43. As needed, shift the mount position of wing gauge
wheels to keep tires between rows of
post-emergence crops.
Note: When relocation gauge wheel mounts, position
them as far out on the wing as the tire track
requirements allow.
Reset and Disable Pumps
44. With side dress installed, both the row count and
swath of the implement change. Configure the
ground drive pump or controller console for 13 rows
and the wider swath. “Fertilizer Rate” on page 64.
45. Take steps to prevent the rear boom pump from
operating. Remove the contact wheel or a chain from
a ground drive. Leave the hydraulics disconnected
for a hydraulic pump.
