Is it a bad idea to put an 8 row header on a 2166. It is a 97 model and only has 1100 hours on it already running a 25' bean head with no trouble. moving to a 16 row planter and can't see trading combines. Thanks in advance for any input.
The answer probably depends on the yield and moisture of the corn you are harvesting.
My neighbor had a 2366 with a 6 row head and went to an 8 row head; He got into 200 bushel corn at 23% moisture and could only go 2.5 mph. He was not happy and bought a 2388.
This year my 2388 with an 8 row head could only go about 3.8 mph in 240 bushel 17% corn. It had the power to go faster but the rotor loss became excessive. I even installed round bar concaves and removed rods but it hit a capacity limit in this high yielding corn.
Maybe in 150 bushel or less corn you might make it go but for me I do not want anything with less power or capacity than a 2388 with an 8 row head.
One other thing…you never have enough grain tank capacity with the 8 row head. I put the biggest grain tank extension on the 2388 and still have to fool around when I am opening up a field. It was nice to go all the way around when I had the old 1660 combine with a 6 row head. I have some part time help running the grain cart and they never are in the right place when I am opening up a field.
we bought a 2166 new in 97 put a 1083 on it worked great .not sure if are you 4wd, we were, some hills had to switch to 2wd to reverse it. the next year we had a 2366 and ran that corn head and a 30' 1020. I would have one if I had a 16 row planter in a heart beat.
We ran a 2166 on an 8 row for quite a few years. It handled it fine. The fuel pump was turned up so that did help quite a bit. With the smaller rotor and seperating area, it is definately harder to keep corn in the machine than with an 88. But it can definately be done. Just takes a good operator and someone that KNOWS how to set a combine.
We had a 1063 on a 2366 & then switched to a 1083 & couldn't see much difference in how the combine handled the heads. Was able to run 4mph with the 1083 in 200 bpa corn without much problem, though had to slow a little when unloading on the go.
If the head is a poly head you shouldn't need any rear weights, least we never ran any on the 2366. If it has metal snouts you may want to add a few weights to it though you should be able to get along without any, especially with 4wd
We had a 1995 2166 with 4000 hours on it and ran a 1083 poly on it the whole time we had it(bought used in fall of 2000). We combine 85% terraces and didn't have a single problem. We did have 1200 pounds of weight on the rear end and also ran 30.5 tires on it. We did not run a bin extension on it and would not recommend it( to hard on axles and tires). We did finally trade for a 2003 2388 before 2007 harvest and this combine kicks the 2166 all over the board. So good luck deciding on what to do.
The limit on the 66's with a 8 row head usually is the clean grain elevator especially in high moisture corn if you have a bin extension. Setting the slip clutch torque up a little like the newer units and having a hyd drive bubble-up auger in the bin makes all the difference in the world. Then it should work fine with an 8 row header.
I learned to catch on the "go" with a 1086 and a 450 bushel wagon from a 1460 and an 8 row head. I know a few guys that still use a 1460 with 8 row heads. The combine will handle it, just weight for it and be patient while using it.
We went from a 1660 to a 2188 and dad claimed the leap felt a lot like the jump from the 1460 to the 1660. All those have had 8 row heads.
When you are looking at trading do not get the 2208 because it is much heavier than the 1083. We have had excellent luck with ours and I consider it to be a good head. It's just going to be heavier than your 66 is going to want to play with. If you trade up to an 88 I would recommend the 2208.
