Tractor

Tractors are a form of machinery commonly used for agriculture and transportation farmers. A hallucinatory tractor almost ran over Mike Yates and Sarah Jane Smith. (DW: Planet of the Spiders) This must have been very unpleasant for Sarah, whose parents were killed when their car was hit by a tractor. (SJA: The Temptation of Sarah Jane Smith) The Eighth Doctor drove a tractor that he and Kala had stolen through numerous objects. The Doctor declared he had always wanted to drive one.
