I assume the truck has a PTO to run the grinder?
Doc, the grinder pictured gets it's power from the truck engine. Must be a hella stout 'transer' box!
Gopher, I should clarify that we hire the grinder work, that is not our machine. They are indeed quite expensive and it would make no sense for us to buy our own. I forget the rate, around $200/hr I think.
Roger, felt like that song more than once!
Sam help a dude out.. when do you chop hay,why do you chop hay and what percentage of your hay through the year will you chop?
Salty,we chop maybe 3-5 times per year, Nov-April. The hay gets chopped so it takes on a 'mixable' form and in turn gets blended with corn silage and a 3/16" pellet in a mixer wagon. That is our feedlot ration. My dad mixes the loads so I'm not sure how many ton of actual ground hay we use a day.
This season we've probably ground up about 400 full size(1300-1600lb) round bales and that would be roughly 25% of our hay supply not including straw. We recently sold our feeder calves so that makes a big difference in how much ground hay we use.
I'll bore you all with the same old hay pile pics but it kinda gives an idea of how it works.
The baby yuppie tractor is pulling a mixer wagon. You dump in whatever feed you have on hand and it mixes it all up with three giant augers. The wagon has load sensors and a scale/weight readout monitor so you know exactly how much you are dumping in.
Far right in the pic is a pile of silage, left of that is a pile of the chopped/ground hay, the open end building holds the pellets and to the left of that is another pile of hay.
We get the pellets delivered from a feed mill. Had a delivery a couple hours ago. Uber handy.
Snake, inside my shelter now sipping on a beer. Man this cow farmin' is tough!
