IH 420 two bottom

Anonymous-0 · Dec 13, 2012

I am interested in a plow for sale a couple of hours away. In the photo the plows sit level on a level floor, but their angles are definitely not parallel.Front plow faces soil more aggressively. Is this normal? Owner has no answer. TIA

If one bottom is at an "angle,then it is 'sprung'.Leave it there.Go over and look at it in person.Both bottoms should line up.

Yup. The distance from any point on the 1st bottom to the same point on the 2nd bottom should be exactly the same.

If the bottoms are not "parallel" then the plow is bent, aka sprung.

About the only thing it's good for is to harvest the bottom units off of, unless they themselves are sprung. Hopefully it has newer Super Chief bottoms on it that you could transplant to an old #8 Little Genius or some other plow with old bottoms on which parts are NLA.

If it has Super Cheif bottoms,one bottom may be tilted down by use of the adjustable top bolt/cam unit.Early top bolts were a cam? type unit you had to remove the through bolt to set,later ones were one piece,had an arrow cast in to show position.That feature was used on most all IH plows I"ve seen with the Super Cheif plow bottoms.Perhaps one is set in the tilted down postion,or,as some guys said,the frog could be sprung.
