from detent signal is sent to the operator input device 108 at a second command block 314 and the logic returns to the start block 300 if the value of the operator input signal at the first decision block 308 is raise detent the logic progresses to a third decision block 316 at the third decision block 316 the implement position signal is compared to the raise limit value if the value of the implement position signal is less than the raise limit value a raise command is sent to the work implement 102 at a third command block 318 and the logic returns to the start block 300 if the value of the implement position signal is equal to or greater than the raise limit value a stop command is sent to the work implement 102 and a release from detent signal is sent to the operator input device 108 at the fourth command block 320 and the logic returns to the start block 300 while aspects of the present invention have been particularly shown and described with reference to the preferred embodiments above it will be understood by those skilled in the art that various additional embodiments may be contemplated without departing from the spirit and scope of the present invention for example the raise and lower limit signals could be reversed to cause the opposite motion of the work implement 102 as described above the automatic implement control system could be activated automatically or the inputs and decisions.
