look at the tires under this vehicle.
There is a guy somewhere around my area, what uses one of these tires as a manure tank. The manure is stored inside the tire. it is the machine with the lowest compaction. The tire stores abouit 5.5 m3 of manure. An extra 2m3 steel tank is mounted on the tongue.

Renze,

Do you have a picture of that machine, so I could use it on the site?

That looks like those vehicles that are used in the arctic tundra for exploration. They must have very little compaction. If I remember right, I once saw a demo pic showing one running over someone's legs with no harm done.

Admin, and Woodbeef,

The rolling manure tire is propelled by a Valtra M900. The front axle is removed, and the manure tire is connected directly to the tractor, making it an articulated steering.

I will try to find a picture.
