I was given an Oliver 2 Bottom Plow from my uncle.  Currently I have gotten everything loosened and functional except it doesn't stay down when I pull the rope trip.  This plow was bought new by my grandfather and his brother &quot;after the war&quot;, so '45 or '46(?).  Then it was used to put in the whole crop in one week day and night with the Oliver 70 tractor only being shut off for oil changes.  The plow has the squeeze type handle with notches for the furrow wheel and a crank handle on the land side with the rope trip.  My Mother-in-law said that you were supposed to pull the rope to trip the mechanism at the sart of the field to lower the plow into the ground and then again at the end to raise it again.  When I pull the rope, the plow drops and then raises right back up.  The moldboards have the Raydex decal on the back.  Steel wheels all around.  Any help would be greatly appreciated.  I plan to use the plow to break up the ground for a shelter belt and then restore it some day.
