Abstract: A supply apparatus for supplying wrapping material to a wrapper inlet of a baling chamber, in which a bale is to be wrapped. A reservoir supplies the wrapping material to an upper driven roller forming a lower part of the wrapper inlet. The wrapping material is guided to the wrapper inlet from above the wrapper inlet. A displaceable supply unit is located between the reservoir and the upper driven roller, the supply unit being moveable between a baling position and a wrapping position about a pivot axis located above the wrapper inlet. A free end of the wrapping material outside of the baling chamber is protected by the displaceable supply unit from air turbulence during operation of the baling apparatus.

Abstract: An assembly system for components of a pressurized fluid supply system for an agricultural vehicle includes a body having at least one fluid duct connectable at one end to a pressurized fluid supply and having a socket at the other end. A detachable component such as an accumulator or oil filter is connectable in releasable mechanical engagement with the body to receive pressurized fluid from the at least one fluid duct. The engagement results from insertion of at least a portion of the component into the socket and rotation of the component to a locked position. The body has at least one discharge duct extending therethrough. In a partially rotated position of the component portion within the socket, the component remains mechanically attached to the body and the fluid duct and discharge duct are in fluidic connection, discharging accumulated pressure in the fluid duct.

Abstract: In a hydraulic system, such as for a tractor or other agricultural vehicle, a main supply pump supplies fluid to a steering system through a steering circuit and a second pump supplies fluid to a cooling fan motor. The second pump is connected with the steering circuit to provide a second a source of fluid to the steering system when the main supply pump is unable to meet demand. A prioritization valve regulates the flow of fluid from the second pump to the motor. The second pump acts as a secondary pump for the steering system and drives a cooling fan.
