I saw an episode of "Tractor Talk" on RFD TV and they had a rundown of the BigBud. It was almost back home in Montana(?) close to where it had been built.
They were filming it pulling a huge trailing type chisel plow. It must have been about 100' wide. He was bragging that he could cover about 70-75 acres an hour with it! That's over an acre a minute.
In one segment, they showed a CaseIH 400 horsepower four-wheel-drive tractor with duals driven by the owner's brother next to the BB. From the distance, it looked to be about 1/3 as big as the BB.
Truly an awsome tractor.
