Thanks for the tips Garry. :thanku:
I did weld the new hitch at a slight angle although it was done by eyeball and not with a protractor so I'm not sure exactly what angle I ended up cutting it at. The plow actually tracked pretty well and other than flopping from side to side when I pulled it out of the ground and walked the tractor around the outside of the garden to line up for the next pass. It did a surprisingly good job in the dirt. My rows were not terribly straight as they relate to the edges of the garden but I think that was operator error and not tractor or plow shortcoming.
I'll look into ordering a new ignition coil and putting it on.
Here is a picture of the 2012 addition to the garden after plowing.
There is another similar sized garden just out of frame up the hill that was the garden last year.
Here is a pic of what I threw together for the hitch. The 'loops' are 3/8" round stock bent on a compact bender and welded to a vertical piece of 5/8" round stock. You can't really tell from the pic but there is another 3/8" steel "U" shape that is long enough to loop around both the screws on the plow frame. Excuse the poor design and crude welds- I was racing the weather to get everything plowed before it rained and a usable mount now was worth more to me than a well designed hitch after the soil was wet and heavy again.
From this pic it kind of looks like the plow 'frame' comes in at a 90° angle to the back of the tractor but it actually does have some angle to it. The holes you can see where the u bolt that should hold a coulter are almost perfectly level when the tractor and plow are parked on a flat surface.
