Re: Bought a 2 bottom plow but...
You have got to run the stabilizer arms with that plow or leveling it and adjusting it just won't help until you do.
The "drift to the left" IS going to happen without them as that is the "equal and opposite reaction" from turning the soil to the right.
Most usually, the stablizer arms are a single piece of 5/16 or 3/8 inch thick flat bar stock with a pair of holes in them. One hole at either end of the bar. One end goes on the hitch pin of the implement after you attach the lifting arm. The other end attaches to the pin of a bracket designed for it, which is then bolted to the tractor (under the axle) and held in place with the fender bolts.
As you found out, you can only shorten those chains just so much before you can't lift the plow out of the ground.
With ALL ground engaging implements that moves the soil in only one direction (such as a plow), you have got to have those stabilizer arms if you want to keep the implement dead center behind the tractor.
The sideways drift was a key factor in the development of the 3 point hitch. It permitted cultivation implements to track in a fairly straight line behind the tractor, even if the tractor's direction was wandering back & forth slightly. In other words, it is in the nature of every driver to pull the steering wheel slightly to which ever direction the operator turned his/her head and upper torso, to look back at the implement. That slight pulling on the wheel, turned the tractor ever so slighly, but the cultivator or whatever followed a fairly straight line.
