26 define an outlet perimeter in the outlet plane 108 and the area within the outlet perimeter defines the outlet area 112 in the outlet plane 108 as a result of arrangement of the front wall 14 the back wall 18 the left side wall 22 and the right side wall 24 the outlet area 112 is larger than the inlet area 104 see fig7 the outlet area 112 may be between about three percent and about twenty five percent 3 u2266 x u2266 25 larger than the inlet area 104 in some embodiments the outlet area 112 may be more than about four percent 4 larger than the inlet area 104 in other embodiments the outlet area 112 may be about eight percent to about nine percent 8 u2266 x u2266 9 larger than the inlet area 104 in the illustrated embodiment the outlet area 112 is about ten percent 10 larger than the inlet area 104 the inventive arrangement provides a dipper 10 that improves performance in digging for example the dipper 10 may have improved fill dump and or full dump cycle time the dipper 10 may have reduced drag during digging the dipper 10 may be advantageous.
