1. An offset concrete screed apparatus for screeding wet concrete slurry, comprising:
- a cross support bar;
means for attaching the cross support bar of the offset concrete screed apparatus to a liftable arm of a motorized vehicle;
at least two lateral support bars attached to the cross support bar;
a screed bar attached to said at least two lateral support bars;
one or more hinge assemblies attached between the at least two lateral support bars and the cross support bar, wherein the one or more hinge assemblies prevent the at least two lateral support bars from hinging downward by more than a predetermined amount from horizontal, defined as a support bar angle, wherein the support bar angle is no less than 3 degrees and no greater than 45 degrees;
wherein the screed bar is positioned offset from the motorized vehicle allowing the motorized vehicle to be driven outside forms containing the wet concrete slurry during the screeding.

Abstract
Methods and systems for making and using a wide swath offset concrete screed apparatus for screeding wet concrete slurry. The apparatus includes a cross support bar, an attachment mechanism for attaching the cross support bar to a liftable arm of a motorized vehicle, and lateral support bars for attaching a screed bar to the cross support bar. The screed bar is positioned offset from the motorized vehicle used to operate the screed, allowing the motorized vehicle to drive outside the forms.
