A beet harvester is similar to a combine harvester, weighing 11 tonnes and measuring seven metres in length. Its function is to pull root vegetables out of the ground. Once again, hydraulics expert Steve ‘The Prince of Pressure’ captains the Red Team with Ed ‘The Professor’ Rycroft leading the Blue. They each have to design and build a machine from parts scavenged from their harvesters, capable of destroying a building made of foot-thick, reinforced concrete walls that has stood for more than 50 years. The teams have a kitty of £500 each for extras and they have just four days to build their wrecker before being allowed half an hour each to cause as much mayhem as possible. However, when Jason explains that the teams can’t just get in the massive harvesters and drive at the building, he is met with a chorus of groans.
