Transport Lock pin on JD 1240 Planter??

[OUBrew]

Is there a transport lock pin on this planter? I don't have a manual and want to get my plots planted asap. I connected the hydraulic cylinder but the planter will not drop. My guess is there is a locked transport setting? Any help would be appreciated.View attachment JD 2.pdf

Nevermind...found it. Two steel plates connected by a pin.
