Rick, Thanks for the input. I've been surfing, reading, asking and my numbers still indicate that in the context of my plan I should be able to make a decent go of it. Agreed that the 851 is a questionable power source but that is not the key ingredient here as I see it. A better diesel tractor will be needed eventually. Although I have no solid formula it looks like about 40 horsepower will power a Peerless 800 gpm centrifugal pump to elevate and pressurize irrigation water the necessary 25 feet. This fits the tractor pretty well barring mechanical problems. On the production side of this, my property has made 5 large rounds per acre in a perfect year about 5 seasons ago. I had it subbed out at the time and know none of the particulars, just that it was an excellent rain year. If quality management, chemicals, and irrigation could get and keep production at 5 bales an acre that should be 100 to 110 small square bales. Given that the price around here for high quality horse hay is to $6 to $8 and this year is much higher due to drought I'm thinking there's some margin here for each of the probable 5 cuttings I expect. What do your think I'm missing here? Thanks again for the commentary>
