Oh yes, I have the plow set to the very far right, the way it needs to go. It still doesn't track straight, but I'll take the bolts out anyway and try.
Also, I was watching the 8th annual PA plow day video and noticed this at 27:18. This guy has a bolens gear drive and plow like mine, and his is straight up and down as it should be. The hitch is also slanted like mine is, but the opposite way.
Yes that is my dad and his Bolens. Looking at your pictures it is hard to tell but it looks like you have your sleeve hitch mounted crooked. The front of the sleeve hitch has two vertical holes. Looks like you have the right side mounted on the bottom hole and the left side mounted on the top hole which is making it lean to the left. They should be in the same hole where the hitch is level.
Do you have another plow to compare the angle of yours to? I see that it was re-welded.
