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 operation 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.

the adjustable top link until the

 

swing mast closes tight against

 

the “A” Frame and the AERA-

to 1/4 inch off the ground. This

 

causes the combined weight of
