When the sections are on the ground, continue to operate the
hydraulic lever to fully extend the wing cylinder so the cylinder pin is approximately in the

Failure to fully extend cylinder will damage the cylinder or the
framework.

WARNING:
This harrow is designed to be pulled in the field with the harrows fully on
the ground and all cylinders fully extended at all times. Pulling the machine with the
sections lifted off the ground over extended distances or lifting the harrows off the ground
for turning at corners or end of rows is not recommended and will result in premature
wear of the cylinders, pins, and frame components and those parts will not be warrantied.
Lifting the harrow for a short distance to unplug any residue clog is acceptable. Never
back up with the harrow sections on the ground. Always lift the sections off the ground
before backing up. Do not turn so short as to make the wing wheel roll backward.
