I was thinking about the numbers on IH tractors and i thought that maybe the numbers represent something. i think in some tractors the last number on the model number tells the number of cylinders in the engine. Like 574 has 4 cylinders and the 966 has 6 and the 1468 has 8. and do the rest of the numbers tell horsepower like 574 has 57 horse power and the 966 has 96 and the 1468 has 146. this is just a thought that i had.

Dan: These theorys I think are just that as they do have some holes in them. Example 100, 130 and 140 were not 10 to 14 hp, a 1066 is not 106 hp. a 4386 is not 438 hp Many of them were close but I think just coinsedence. If you look more closely 856 to 966, sounds reasonable 1256 to 1066 makes no sence, now if they had used 1266 it would sound reasonable. But then looking at where IH went, maybe it just represents how good management were with figures.

Hugh, Just when we had our ABC's down pat, IH had to go and confuse us by introducing us to arithmetic.

at least they knew how to number a tractor series till the 88's then they still had it pretty well right.

i guess it doesn't, just doesn't seem right that a 3230 and a 4240 are part of the same series. But after the radial tire scolding i got, this one shouldn't surprise me any.

Dan, I don't know what type of ground you have in your area, but here in Mid Michigan, a 400 will handle 2 bottoms fine, struggle with 3 bottoms except in sand, and won't touch 4 bottoms except when turning in headlands.

Dan: I can quite safely tell you no 300, 350 or 460 pulls 3 by 14 or 16 with no problem anywhere. The will struggle with it under the very best of conditions. My farm was a sandy loam, no soil anywhere plows as easy as sandy loam. I used a No.60- 3x16 plow behind 300 and 4x16 behind 560D. On a field 1,000 feet long 560 would pass 300 about every 5 to 6 rounds. I also later used a 5x16 semi mount behind 656D. None of those tractors ever broke any speed limits with the plows listed behind them. That suited fine as sandy loams quite often have a few big stones. I can also tell you, trip bottoms don't always do their thing if speed is involved.

Dan, It took a W-9 to handle 3-16 on a consistant basis here. 460 barely handled 3-16, unless you want to plow in 1st or 2nd gear all day, provided you had traction.

you better peel the 400 sticker off to see what it really is then. I havent seen a 400 yet that could not pull a 4 bottom plow. and if it struggles with a 3 bottom then you got something wrong with it.

Obvious you dont have heavy blue clay ground like we do. Ya just cant go back to the barn and change plows every time ya hit that vein.

It's a better theory than the one I came up with when I first started messing with Farmalls. I had gotten the idea that the number was the horsepower, so a 340 had three hundred and forty horspower, a 460 had 460 hp, etc. But I was only ten.

That would make the 4568 we use one nasty son-of-a-gun, wouldn't it?

Paul, Just curious as to how big of a plow do you have for your 4568

in that heavy clay? Wayne

Wayne, As a mater of fact, we no longer do any plowing. We (my cousin whom I work for) farm approximately 4,000 acres, all no-till. The 4568 is the main power source for a 30' no-till grain drill. We also use it in the fall at times to pull semi's out of the fields if we get stuck. Thats rarely since we shuttle a grain cart from combine to truck. Occasionally if we cut up a field too badly during a wet harvest, we may pull a 30' winged disk to cuff and even out the places we cut up. We havent plowed in over 15 years, however many of the local farmers still do.
