Simple financial formula - I love'em! But I'll add a little mud to the clear water - keep in mind the grain you could save by owning a Gleaner vs hiring a custom operator with an inferior make. Plus the convenience of harvesting when YOU want to vs when your custom guy gets there. I'd best shut up now in case any of MY custom clients should read this!! My guess, and that's all it is, would be approx. 3,000 acres minumum. I guess I have always thought 1,000 - 2,000 for a class V, 2,000 - 3,000 for class VI, and 3,000 - 4,000 for class VII (minimums). Perhaps others have different opinions here. I'm also talking corn_soybean country. Wheat may mean different numbers. Tom l.
