Abstract: A tilt bucket may include a front structure having an outer surface, the front structure including a base plate with a bottom surface. The tilt bucket may include a bottom edge and a curved wrapper extending between the base plate and the bottom edge. A ratio of a maximum distance between the curved wrapper and a first line extending from the bottom edge to the tangent point on the outer surface of the front structure, taken substantially perpendicularly from the first line, relative to a length of the first line, may be about 0.64 to 0.70.
