[AT] Finally done

Thu Oct 28 04:31:21 PDT 2004

Dudley the snap coupler is kind of like a 3 pt hitch turned upside down. 
There is a coupler under the rear axle.  It has a spring loaded pin in it 
and the implement (plow, harrow, whatever) has a tongue with a ring on it 
much like an elongated pentil hitch ring.
You backed the tractor up to the implement.  The tongue would slide into the 
hitch and snap into place.  Then bars or chains that hinged from some point 
on the front of the implement would attach into the arms that extend from 
the rock shaft.  That allowed the implement to be lifted and for depth 
control but all the pulling was done from down under the axle.   The lift 
arms (rock shaft) were hydraulically controlled by a spring loaded rod 
attached to the sanp coupler down under the axle.  (the exact arangememt 
varied depending on the model of tractor)  When the load (going forward) on 
the implement got excessively heavy (example: plow goes to deep or hits 
heavy dirt or a stump) the hydraulics would lift up on the lift arms and 
transfer weight to the rear axles of the tractor (thus the traction booster 
name).  The implement tongue is sort of like a fast hitch tongue except that 
it rides a little lower and has a ring on the front instead of hook.  Also 
the snap coupler is a less rigid hitch and would allow the implement to 
swivil like a trailer being towed if the chains were not connected up to the 
lift arms.

I've gotta run.  Hope that is clear if not I'll try to explain it better 
later.  I guess a good picture would help most.
