John Deere KBA/KCA Harrow

[Southern4020]

Could someone tell me the difference in a John Deere KBA and a KCA harrow. I really dont see a difference in the PArts book that stands out to me.Thanks

Probably the KCA is a later model of the KBA. I briefly looked at parts diagram for these disk harrows and found 1 referral to KBA?KCA in this section at bottom of page in the footnotes

FRAME, WHEEL, KBA AND KCA (C) FOR 6- AND 7-1/2-FT. KCA.
(D) FOR KBA ONLY(E) FOR KCA ONLY.

Would have to do some checking to be sure but I believe that the KCA is a wider blade spacing than the KBA and built at the same time frame. Everything around here is the KBA series.

KCA disk used 9 1/2 spacing ,20" blades 6'& 7 1/2'wide only; KBA 7 1/8 spacing, most used 18" blades, up to 14' wide.. KBA replaced KB series in 55' made until late 60',,
