UNDERSTANDING HOW THE SWING HITCH OPERATES (PRIOR TO HITCHING
TO TRACTOR)
With the swing stand lowered
and the swing mast rearward to
disengage the swing lock, grasp
the hitch pins and rotate the
“A” frame to simulate opera-
tion in a sharp turn. Release
the hitch pins and slowly pull
the swing mast forward as it
would be pulled by the top link
during lifting. Notice how one
mast chain tightens causing the
“A” frame and unit to realign
and the spring on the lock link
is compressed to make the
swing lock engage upon align-
ment. Now push the swing
mast rearward against the lock
link tab to disengage the swing lock and loosen the chains to allow sharp turns again. This
demonstrates how the top link of the tractor lift system switches the AERA-vator between the
trail and lift modes.

CORRECTLY ADJUSTING THE HITCH TO THE TRACTOR
A category 1 hitch tractor is required with the lower links stabilized. With the AERA-vator
swing stand lowered connect
the lower lift links to the “A”
Frame and top link to the swing
mast. Push the lift control lever
on the tractor to the completely
lowered position. Lengthen
the adjustable top link until the
swing mast closes tight against
the “A” Frame and the AERA-
vator swing stand is lifted 1/8
to 1/4 inch off the ground. This
causes the combined weight of
the AERA-vator and the tractor
hitch components to be trans-
ferred to the tines. This ex-
tended top link also causes the
