New Zealand - Timber Industry - A bullock team at work in the bush in Ngongotaha, Rotorua District. - 1/6/1922 - Unknown Photographer - Originally published in "The Auckland Weekly News" #336681 - A bullock (or ox) is a mature, desexed bull. Bullocks are usually harnessed in pairs as their strong necks make them ideally suited to wearing a wooden yoke which efficiently transfers their draught power through a chain or pole to the load. When two or more pairs of bullocks are harnessed together to perform draught work, you have a bullock team. - Bullocks have been used singly and in pairs or teams for much of human history. Bullock teams had their peak in the late 19th and early 20th centuries, particularly in the rapidly developing countries of Australia, South Africa and New Zealand. In Australia, as many as thirty bullocks driven by one man, were used to haul enormous loads on massive wagons long distances from outback farms and stations to their destinations on the coast.
