just filling in some blanks on key choices,
d100's, x300's, currenct x500's 1 key 3 styles (also fits 3xxxe series cuts and lt mowers)
zero turns, premium graden tractors (as well as lx mowers and old x4/x5), gators 1 key 3 styles
farm tractors pre-dating comfort gard cabs, windrowers, full size backhoes, early 4000 ceries cuts, etc 1 key 2 styles (still used today on many construction machines and windrowers, considered the old style keys
2305, 2520, etc 1 key 2 styles
790, 3005, etc 1 key 2 styles
mini excavators 1key
skid steers 1 key (sometimes works on premium lawn mower, gators, and vice versa) 2 styles
forage harvestor 1 key
current 20 series tractors and anything previous w/ comfort gard cab 1 key 2 styles (the std red one everyone is used to seeing now)
vandal keys 1 key (optional on current farm tractors)
and of course the real old keys from stuff from the 70's and earlier like indek keys, etc
the multiple styles are just the different key pads or if they even have them.
Am more familier with the ag stuff than the construction probably missed a few.
