The paaltjasker was built in 1970 in Allingawier and is part of the Aldfaers Erf Route, a route along museums in Allingawier, Exmorra and Piaam. The tjasker has four Common sails, which have a span of 5.45 metres (17 ft 11 in) and can pump water in a circuit. The tjasker is owned by Stichting Aldfears Erf and can be visited when the museum is open. The name is derived from the nearby farmhouse, also part of the museum, called De izeren kou (English: The iron cow).

The boktjasker was at first located near Blessum where it drained a meadow. It was replaced by a metal windpump in 1954 and donated to the Friese Maatschappij voor de Landbouw English: Frisian Cooperation for Agriculture who restored it and erected it near Ryptsjerk though without making it functional. It was moved again in 1972 and now drains some plots of meadow north of Augustinusga. After 1972 it was also restored in 1988 and 2012. It is one of only three remaining boktjaskers. The Common sails have a span of 5.80 metres (19 ft 0 in). The tjasker is owned by municipally Achtkarspelen and can be easily reached on foot from the public road.
