Faunsdale, AL | Yes, disassemble and pass out through the door. A few parts can be left bolted together, but most are disassembled.
We have the crew to do it because we still use tractors and wagons to fill upright silos as well as plant conventional tillage corn and soybeans, work heifers, raise calves ourselves etc.
"putting up an unloader" is usually a 2 day process unless the silo has only been recently filled and there is little spoilage on the top to throw off. As the months go by, the amount of spoilage increases and by the last silo we open every year, it may take most of a day to throw it off, level the surface, disassemble the unloader and move it out of the old silo and make repairs as needed. It may take 2 if it's so hot that the crew can't stay up there once the sun gets up in the sky in June for example. Of course when they come down, they don't punch out and go home, they go on to other jobs which can be done in the heat of the day.
If I could find a method of covering the top of a silo to drastically reduce the spoilage, it would be worth quite a bit. This year we used pieces of silage film underneath our tarpaulin covers for each silo. That was slightly better than before, but not much. We have tried molassas to seal it with, but that just made more mold. The last silo had a foot of silage blown in over the top of the plastic film to weight it down and still had spoilage around the edges probably 5 feet down. We do not leave that and let it be incorporated into the good silage the unloader is throwing down.
It might have worked better if the silo had had a top on it this summer, but the April 27th tornado also removed the roofs of the full silos as well as knocking down the partially filled and empty ones. Finally got the tops replaced 4 months after the new crop silage was put back into two of them, so there was some rainfall that would have gone into these we wouldn't normally deal with.
