I have an original Raven Cruizer and long box Smarttrax in my tractor.  Both are in good, working condition.  I know they are not serviced anymore and was wondering what would be a good upgrade.  The tractor is used for spring and fall tillage, so WAAS signal works fine for the application.  I want something compatible with the Raven hydraulic box that is already on the tractor.  I see the CR7 is the replacement for the Cruizer.  Is this what I want? Thanks.
