Combines m2

Close or check the real concave clearance, with age it widens and doesn't thresh the grain well enough. Open the chaffer more and close the sieves more and use the air to clean the grain. Make sure that you are not overloading the sieves with too much chaff though. And I had problems on the hillsides(even with a sidehil blower) in high yielding corn and a 6-30 head, sometimes had problems with an 18'FCB in beans too. Finding the long Shoe is not easy for the M2_3, this too can correct the problem. I moved from an M2 to an N6 and took care of all my loss problems for yield and sidehills.

This sounds nuts but check the cleaning fan to make sure it is not plugged. If plugged, the combine will do as you said yours does.

VAlVE lASH COlD IS .018, HOT IS .015. 150 FT lBS. TORQUE ON THE ClY. HEAD

We've been going to 165ftlbs as long as I can remember with no retorque. Used to be 150 and retorque years ago with old gaskets. Retorqueing with gaskets used nowadays may damage the sealup. Maybe don't matter much but I thought I would pitch in on what we do. Old manuals would say 150ftlbs. Newer manuals say 165ftlbs.

I had M2 snn16968 and it was a 1977 model. The engine is the very dependable Allis 301 which have been known to give lots of hours of service with very few problems. Mosh M2's around here used 630 corn heads but I have seen a few with 430's but they needed narrow tires on the front.

The M2 should definately impress you with 6 rows on the front. I have operated one for 2 years and it will definately suprise you how much and how fast it will eat the corn. We have never has a problem with it having a "Tummy Ache" it handles the 6 rows well and you will be doing yourself a big favor to get the larger machine! Good luck

I too went from an F to an M2 several years back. If you liked your F, you will love the M2. The capacity seemed about 50% more than my F would handle. The M2 is an all around easier machine to operate than the F, my opinion. The 6-30 won't have problems until you hit very high yields or steep sidehills, or both. I started to have loss problems when I started getting a constant 180bpa and then added sidehills. The machine will handle it until it gets to the shoe, that is where the overload problem began. I was able to solve my 6-30 problem and high yields with an N6. While the 4-38 was on the M2, I was never able to overload the machine. Overall the M2 with a 6-30 is a good machine, I had to stress it to find faults with the performance. The man who bought my M2 still has it on flatter ground and lower yields and loves the machine as much as I did.

I have an M2 with 315 flex and 6-30 black corn head if you have not bought yours yet you may want to look it is in very good shape.

Russ, I know a guy with an A438 set on 36" for an M, and an Orange Stripe 438 set on 38" for an l. I think changing the drives would be harder than widening the row units.

How much and where are you locatedIJ
