Abstract: A bucket for a work vehicle includes a bucket main body portion, left and right boom attachment portions, and a spill plate. The left and right boom attachment portions are adhered to the rear surface of a basal plate, to the left and right sides of the center of the basal plate in the lateral direction, respectively. The spill plate includes a first spill plate portion and a second spill plate portion. In a top view, the second spill plate portion includes a forward edge line extending in the left and right directions from a center of the bucket main body portion in the lateral direction, and first left and right edge lines extending to first and second connection points rearward and leftward and rightward from first and second front ends, which are the left and right ends of the forward edge line, respectively. In a top view, the first spill plate portion includes a second left edge line, a second right edge line, a third left edge line, and a third right edge line.

Abstract: A water-treating agent comprising a ternary copolymer of conjugated dienesulfonic acid/(meth)acrylic acid/2-hydroxyethyl (meth)acrylate, or a ternary copolymer of conjugated dienesulfonic acid/(meth)acrylic acid/(meth)acrylamido-2-methylalkanesulfonic acid ternary copolymer, is effective against scaling and fouling in water systems and a method for treating water with the water-treating agent. When combined with a corrosion inhibitor, the water-treating agent exhibits an excellent anti corrosion effect.
