Yes, that is one FLAT tire.
This is the way it works: the chopper chops the alfalfa and blows it into a wagon. The wagon is being pulled by a tractor. When we harvest, we have two tractors pulling two wagons. Once one is full, the driver dumps it on the pile at the barn. Then goes back. It's a cycle so that the wagons never stop moving and the chopper never stops moving.
Unless you get a flat tire!
The wooden blocks on the ground are for helping jack it up. You have to jack, put a block under the axle, put a block under the jack, etc. Since it's full of chopped alfalfa, it's really heavy, too.
Thankfully, we had another wagon we could use. Nice to have a spare - tire and wagon.
Kris said this is the busiest week of his life. He's working every waking hour, and when he's chopping and such, he's planning what he needs to do next. But he said that he's not sure if it's like this every year and he forgets about it, or if it really is more busy.
I guess next year we can just check the blog posts!
