I’ve double-checked our logistics system, and yes, the replacement is for a Mower Pro module.
Please let me know if you have any other questions, and I’ll be happy to help.
I haven’t read the whole thread but here is what I have found out.
This issue seems to be caused by the Pro mowing head.
I can only get the blades to spin up while it sits on the charging dock. As soon as I drive off of the CD into a work area the blades stop.
I ended up putting my M1 head on to be able to mow. It happily mows with the M1 head
