I have read complaints about the wheels locking on self propelled egos. If I don't use the SP feature, will the wheels lock? One thing I like about my non-sp is how maneuverable it is; wouldn't want to lose that.
The roll back safety lock does not engage if the SP is not being used. It only engages when the SP system is in use and it is soooo simple to work with. Just disengage the SP one step before reversing.
