interesting. If you look at the specs the 854 and the la1055 are very close in capacities, kubota numbers their loaders according to the lift capacity but they changed the location (at the pins vs a set distance out) where they took the rating so they are essentially the same capacity and to know that the loader from the MX series fits the older 40 series grand is nice info to have for those that are trying to retrofit a loader on an older tractor.
are the hydraulic connections on the LA1065 on the inside of the bracket like the LA854 or outside the bracket like the LA1055.
