1. An apparatus for use in conjunction with a powered vehicle to lay out and take up a long length, wide width flexible sheeting material comprising in combination:

  • a framework adapted for mounting engagement on a powered vehicle such as to be carried over a ground surface by the vehicle, the framework having a transversely positioned framework arm extending outwardly at each end thereof;

    pivot means attaching each arm to the framework;

    means associated with each of the framework arms for journal-mounting a shaft between them;

    an arbor assembly including a cylindrical mandrel having each of its ends journalled to a framework arm so as to be rotatable about a longitudinal axis, said mandrel adapted for carrying a long length, wide width flexible sheeting material thereon in a wrapped and layered orientation about its surface extent;

    means rotating the arms about the pivot means to a lowered position for loading and unloading the mandrel and to a raised position for rotating the mandrel; and

    a hydraulic system to power and control the rotation for wrapping flexible sheeting material onto the mandrel and in an opposite direction of rotation for unwrapping sheeting material from the mandrel;

    the wrapping and unwrapping of the flexible sheeting material being accomplished as the powered vehicle is moved to travel over a ground surface area;

    the hydraulic system comprising;

    a hydraulically operated motor mounted on at least one end of the arbor assembly and having a drive shaft engageable with the mandrel, a means to provide hydraulic fluid pressure, a reservoir to provide a source of hydraulic fluid, a hydraulic valve control means to switch hydraulic fluid pressure from the means providing said pressure to the motor driving the mandrel and to return the hydraulic fluid to the reservoir, and a hydraulic fluid circuit comprising a pair of hydraulic fluid pressure lines interconnecting the control means with the motor driving the mandrel, a hydraulic fluid pressure line interconnecting the control means with the means providing the hydraulic fluid pressure, a hydraulic fluid line interconnecting the control means with the reservoir, and a hydraulic fluid line interconnecting the reservoir with the means providing the hydraulic fluid pressure.
