2-Pt Plow adjustment

Need help with setting up the 2-pt plow on my IH 340 utility. Install new points a few years ago and only use it for food plots. I can only get it to go to a depth of 4 inches or so, and less on hard clay ground. I noticed that there is a hole to pin the 2-pt receivers from bending. Should these be pinned?? Currently they are not pinned. Also, there is a handle with notches for on the LH side of the hitch. What is this for?? Should it be in the lower or upper position?? Any and all suggestions are appreciated.

For plowing, those pins should be in the "float" position to allow the plow to seek its own level. The side stabilizer pin should also be removed/in the "float" position to allow the hitch to move side to side.

The handle on the side is the "draft control." It should be in whatever position gives you the desired result. Try different positions and see if it makes a difference. That's really all you can do.

Now you might be plowing as deep as the ground allows. If it's real hard and dry the plow won't go in.

You did say any and all suggestions would be appreciated, so likely you know this is coming: There have been entire books written on this subject. It may be a wise decision and money well spent to get yourself a reproduction manual for your tractor and plow. They go over things like where to put the pins on the hitch, how to set the draft control, adjustments you can make to the plow, etc..

Ah look on the plow mounting , you will see a rectangles bolt head with and arrow , when the arrow is pointing up that is for NORMAL ground conditions and if you want it to suck down deepr ya loosen it and drive it out just enough to be able to rotate it 180 Degrees and put it back in , how ya may need a sledge hammer to force the nose of the shear down if things are rusted up a bit and the bottom will not move . look into the I H parts site for a break down of the plow to see where that adjusting bolt is . With our ground i have never had to turn one . Then there is the leveling of the plow that can for some become a problem , The correct tire width is also important .This is somewhat a little harder with a fast hitch plow then a 3 point . one simple way is to get your tractor on a level paved surface and take two boards/ cement blocks what ever ya can find to put the left side tires up on then set the plow down and see how it lays and then make adjustment with the leveling boxand some times y had to move some bolts on the fist hitch on the plow as you have several mounting holes up there ya can change the bolts to to get the plow to set level .

I grew up with a 340u-we had the f-211 plow. We kept the draft lever in the 3rd notch from the top, the fast hitch receivers unpinned, no change to the leveling crank, and side to side unpinned. It was a great plowing tractor-when starting a furrow in hard ground we set the plow all the way down, so the points hit the ground, and as it sucked into the ground, raise the hitch to the suitable plow depth-7-8. As you raise it a little it will change the point angle-this is where the fast hitch receivers flex. Mark.
