Case ih 1460 setting help

Looking for help setting and adjusting case ih 1460. It was leaving 4 to 6 inches last year, so we tried raising the backend where it bolts to the axle but tried beans yesterday and it seems to be the same. So now looking for ideas. The rear tires are 18.4-16L that are 45" with 10psi and the drive tires are 67*34.00-30nhs that are 64" tall. The throat plate that the header goes on/against is tipped all the way out and we still have about 4" of cylinder to use so we can bury the header but still cannot get the front/knife down anymore (running a 1020 header). We thought about moving the throat cylinders back to the next pinhole that is back and up a couple of inches, but don't think it will help much and might not clear the cart to take the header on and off for transport. We do have some 30.5L-32 drive tires on the international 915 that we could swap around if it might help. Any ideas?
 
Is the auto header control allowing the head to go down like it should?

If you have still have cylinder left to go down it sounds to me like you have electrical or hydraulic issues in the header height control.

What year is the 1460? Pre 1981 or after?

It is after 81 and the header height control is working correctly letting it float and carry fine and when we manually set it down completely we still have that much cylinder available. Trouble is we just cannot seem to get the front/knife down so we aren't leaving 4"-6" of stubble and losing lower podded beans.
We thought raising the rear up with the other axle bolt holes would help, but we didn't gain anything.
Thinking we might need to change tire sizes maybe with either little taller drives or smaller rears, but don't want to really lower backend to much do to fear of changing rotor angle and not letting the beans stay in it long enough to not lose them out the rear. Unfortunately used tires are scare since it is busy harvest time and new would cost around $5000 and no gaur tee that is exactly the whole solution.
Looking for ideas or suggestions on directions to change or things to try. Thanks.
 
Your descriptions are sounding to me like you may be looking
at floating cutter bar issues.

I can't see how tires or leveling changes could be a cure if you
have enough stroke left on the cylinders now to do the job
needed.

I'd look at the leaf springs under the header.

Make sure they are not binding because of trash buildup.

Maybe back-off the adjustment on the springs if they are
exerting too much upward force on the cutter bar.

If you have a manual for the header, it is a good place to start
on the proper adjustment of the springs. You still may have to
adjust the springs different than the book states, depending
on your actual field conditions.

Be sure to lock the header up if working under it.
 
Put one of those round magnetic angle gauges on
the back of the head by where the feeder house
face plate goes in. You want to have about 12 deg.
tip forward. If you are close to that then there
is some other problem other than the pitch of the
head causing this.
 
We are now close to 10 to 15 degrees after talking with several other people and hearing about this angle setup. We actually welded a plate on the throat plate that catches the header so that we had more adjustment then the couple of bolts holes.
We did find that the manual talks about throat distances for tires and what bolt hole to be in and we were correct but off due to the rock/stone trap. We are thinking that the trap is what could be throwing us off. Also changing a few minor things we have noticed on the header. Making some headway.
 
You need to adjust the sickle tilt. There is an adjustment on the header for this. It is how you change them for different tire sizes. I have done it but it was 15 years ago and I don't remember exactly how now. It is described in the header book not the combine book. I know that you can do it on the 1020 header.

30.5 x 32 tires where an option for the IH 1460 and they are taller than your floatation tires. You need to adjust the header not the combine.
 
That could be your problem.Combines that were not factory equipped with traps had a longer feeder house so that will throw your angles all out of wack and there will be no factory adjustments that will get you exactly where you want to be.So the higher you can get the combine standing the closer you will get to setting your face plate on the feeder house at the correct angle.
