The series ran from June 1990-September 1990 if you are loking for it in
your local library.
There are about 28 pages, so it will take some time for me to scan and type
the whole series in.
The drive motors for the Lawn Ranger were made by the RAE Coporation, the
part number was P-20705. The spec was: 187 RPM nospam at 30 in-lb, 24VDC.
Perhaps someone could find out if thay are still available and what they cost.
