Combines Class 8 questionIJ

There is no empirical formula, spec. list, especially no gov't. involvement, etc. The only qualifier for determine a combine's class size is "unjustly" its rated engine horsepower, as mandated by the Association of Equipment Manufacturers (AEM),formally EMI. In the past, there has never been any formal, written or otherwise, guidlines (i.e., the combined values of the: grain tank size, cleaning shoe size, horsepower, etc.) used to determine a combine's class size. Class size didn't really become common place until 1999 when the STS came out.

ROT!! Combine class sizes` have been used for years. Way before JD had even dreampt that they would produce a rotary! Mick in Oz.

Wasn't the N7 Gleaner back in 1981 called the first Class 7IJ I know the N6 was called a class 6 by Gleaner. I wonder when this class thing was dreampt upIJ I thought classes had to with hopper size alsoIJ

The unofficial combine class size has been around for quite a while (someones' best guess, but no industry guidelines available),but wasn't popular until '99 when the industry had to to distinguish between Deere's two STS combines of the same size, specs, diemnsions and engine.

That article hits the nail on the head.

I got a chuckle outta this statement. Quote:More clarity in the classes helps farmers compare machines easier, explains Gerry Salzman, senior marketing director for Case IH and New Holland combines. It takes some guesswork out of shopping for a combine. end quote. So, all kidding aside, if I were to put a big engine in my 1680 to above the class limit, I could actually, legitamatley(sp),increase the class of my machineIJIJIJ I ask this seriously. According to the article, which sounds legit, it should work that way in my interpretation.

good try man but that only works for John Deere lOl

I was always told Horse power and Grain tank capacity then unloading rateIJ can't remember where i heard that..... maybe a mechanic but i always liked that theory

*grin* oh ya, I forgot about that.
