I live in the middle of BIG country. Many of the farmers in the area are farming 5000 acres and more. The big guys will often have 1 newer big combine, tractor, airseeder, sprayer, and often things like rollers, harrows and such as well. The really big guys will usually have 2 combines, tractors and airseeders. And they will often have 2-3 smaller 2WD tractors, a semi and grain trailer, various big grain augers, swathers and so on.
New and Newer combines and tractors come in around $300 000, the airseeders are up to $300 000 and so are the high clearance sprayers, takes about 10 years to drop the price in half if you are buying used equipment, and by then you are running out of warranty. For the price it costs to fix one of these things if they have a major break down, warranty is a selling point!
We're talking 60 - 80 foot air seeders, 30-40 foot headers and 400+ HP tractors. And wheat in this country isn't worth $6/bushell, usually it is about 1/2 of that.
By the time payments are made there is little left to do anything else with.....
