(quoted from post at 10:30:12 02/02/23) Re, your item #2. Pushing the Draft/Position control lever down & having the system lift arms rise, strongly suggest that the linkage is not adjusted properly and/or linkage is bent, worn, etc.
I will attempt to explain why the DRAFT/POSITION lever makes it lift. The two pictures of Draft/Posn linkage show it in Position control with spring NOT compressed & the other show it in Draft mode with the spring compressed. As you move lever into DRAFT mode the arm labeled "L" is pulled such as to toggle the mechanism to the position shown in yellow, thus compressing the spring. That is all normal, but another thing that happens during this movement is that the whole assembly tries to rotate about the pivot where the tag is attached. Once the toggle is completed/spring compressed, this latter "whole assy" rotation is relaxed. But before it is relaxed, this rotation (red arc arrow) pushes the draft mechanism to the left which moves the control arm toward the lift position. Now the control valve is moved to Lift position and you have lift.
Disclaimer: This drawing is for the 8N Ford, but it serves to explain what is happening with you tractor, as much is the same.
