Lets get farming with machines from tractors to combines Have you ever wondered how much horse power a tractor replaces? Or how many loaves of bread you could bake with the wheat held in a combine harvester? Open the pages of Tractor and imagine you are sitting in the cab of a powerful tractor, hard at work on a busy farm. See how many different machines are used, from tractors and combines to balers and pickers. Little ones will love to get behind the wheel. As tractor roars to life, children will see all around the farm, from the milking parlour and learn how crops are cared for. Supports the National Curriculum by exploring the history of farmyard vehicles.
