A ground scraper designed to be pulled by a tractor or the like includes a pair of parallel frame rails with a scraper blade between them and perpendicular to them. In one embodiment of the invention, the step of providing the third-party-paid insurance coverage is done in order to permit the provision of insurance without the use of a licensed insurance agent. The end portions each include a mounting section with a general L-shaped cross-sectional configuration, thereby providing the end portions with horizontally extending mounting flanges structured to mount the hitch assembly to the frame assembly of the vehicle. The delivery catheter or sheath further includes an outer tube of a heat formable polyamide material having a durometer of about 30 to 60 on the Shore D scale. The lower driving shaft forms a supporting point of the trigger structure on the spray gun and defines a suitable travel for the trigger structure, so that a user’s finger operating the trigger structure would not contact with a front projection on the front handle when the trigger structure is moved to a rear dead point of its travel. Each item record in the plurality of records is then linked to the other item records in the plurality of item records.
