I think your right have a good day.

Agreed, it looks like a super chief plow, not a doubt. I have a little advice to share, you may already know this, my dad taught me a trick back in the late 60's early 70's. When you get a plow shined up from use, after you're done plowing for a season, put a thin coat of grease on it to keep it from rusting, that helps keep the dirt from sticking! I think the super chief is better because the share runs all the way which I think keeps it from breaking off, as compared to the chief. If memory serves me right, I think dad had his H like your back wheels are. Enjoyed watching thanks and have a great day.

Boy, someone wanted to get every last millimeter out of those shares! Lol! Yep, they do look like Super Chief bottoms. The long landside on the second bottom is there to help it pull straight & flatten the furrow wall a touch. There's a cast heel that bolts to the end of that, that helps with depth & minimizes some of the wear on the landside. That casting pretty much replaces the furrow wheel. If you need a picture of that, I can post it on the forum. The gauge wheel that's missing may be mounted on a standard sized standard. So, it fits more than one plow & should make it easier to find. The one on my 540 is 1" x 2 15/16" x 22". The one on your F20 looks close. As for your rear tractor tire, slide it off the axle, turn it around & slide it back on. The furrow pan should be firm enough that it won't slip. That & you do have quite a bit of weight there.

Those are Super Chief plow bottoms. Best I remember I ordered new shins, landslides, wear pads, and shares from Shoup. The long landslide on the back is in place of a tail wheel which keeps it straight against the furrow wall when plowing.

What I need to see is how to adjust it. My plow is a little different, but close. Use it on a 1957 F350D.

Hit the plough on the back with the hammer of the plough and the soil came loose easily

I think moving your wheels would be a high effort/low reward operation. I agree, super chief. Also agree that those shares are really worn out.

You have Super Chief bottoms with the most worn out shares I've ever seen...You put new shares and points on that plow and it will plow so easy the 350 won't even know it's back there.
