For many years the buck rake, also known as the sweep rake, bull rake, hay buck, and hay sweep, has been one of the farmer's main tools for hay making. Originally horses pulled it but tractors are now widely used. Old cars are also converted into buckers. The early types of buckers were usually made to carry light loads since they were mainly intended to move hay the short distance from the windrow to a stacker. These types are illustrated in Figs. 1, 2, and 4. In more recent years buckers have increased in usefulness because with motor power they can haul much larger loads, travel faster, and make longer hauls. When a heavy-duty bucker is mounted on the front of a tractor as shown on the cover page, extra wheels should be provided to carry the load. Otherwise wheels, tires, or bearings may be damaged when the bucker is traveling over rough ground with heavy loads. Instructions given here on how to build buckers are general rather than specific because readers will probably find it necessary to adapt these plans to meet their own particular needs.
