Unfold Implement
If the implement is already unfolded, continue at “Install
Wing Gauge Wheels” on page 21. The weight-transfer
shut-off valve (page 11) is presumed to be closed.
91. Fully raise implement. For a 3-Point model, use a 3-
point tractor.
92. For 2-Point and 3-Point models, fully extend parking
stands.
93. For 2-Point and 3-Point models, install lift cylinder
lock channels.
94. Lower implement onto stands and/or locks.
95. If stands are available, set one beyond, but not in
the path of each wing. Adjust the height to match
the raised center section.
96. Slowly extend the fold circuit to begin wing unfold-
ing.
97. When wings are just above level, position the
stands to support the wings.
98. Continue unfold. When wing-ends rest on stands,
wing gauge wheels (if factory-installed), or rest on
wing-end coulters or knives, stop extension. Set cir-
cuit to Float.
Note: Wing locks engage during unfold.
Note: Wing-end coulters or knives are likely to contact
the ground. Slow the unfold as this point nears.
