Ted,

The Challenger MT series has a system like the Deere.  Every comment you made would apply to the Challenger system also.  There is no way to edit a sequence.  You can not name and save a sequence for future use.  Timing of a sequence is very difficult to set and get right.  Also on the Challenger system, there seems to be a delay from the time you push the button to activate the sequence and when  sequence actually starts.  This makes it very difficult for me to use the button to do things like raise the planter.
