There are many differences between the disk models you listed from weight per disks to type of material utilized for frames & differences in brg types. Also disk diameters/thickness offered were different along with disk shaft sizes

KBA & RWA were lighter duty with AW being in the middle & BW/BWF having more weight per disk blade.

I suggest you study each disk model parts catalogs for the many, many differences in models.

There are more models built during similar time frame. Parts catalog preface will normally show either starting date of manufacture or total yrs of manufacture similar to photo.

The KBA was a light very flexible disc to use after a plow. Many were pulltype without transport wheels. Very popular with the Amish (They have a shop that builds brand new ones in PA.) The RW and later RWA were a rigid disc with no flexibility. The AW was almost the same as the RW-RWA except that there was some limited flexibility built into the frame. These were all still mainly for farms that plowed all their land. The BW and later BWA-BWF were built much heavier because farmers were starting to do minimum tillage and needed more penetration as well as cutting widths were getting bigger. Tom

We had a 14 RW dad bought new in 1958 or 1959. Worked good in plowing but was too light to do a good job in corn stalks.

Two disks we had during that time frame that you didn’t mention was the FW and LW. Used the FW behind a 830 and later on a 4020. The LW was used behind the 5010 and later 5020.
