The front axle on the L4760 & up is beefier. Coincidentally those machines can also be speced with the big loader instead of just the small or medium one that the 2 "small" ones can take. At some point they change to CAT 2 links on the 3pt.All the Grand Ls share a common Owners/Operator's manual. Aside from 6" difference in width and varying engine HP there is little difference between them.
The height/width/length of the various grands is a result of the different tire sizes, with the higher HP machines getting bigger tires.
Which adds up to a few differences, but nothing to significant.
