Best you could add is probably a la1055. Problem is that they start this loader on the l4760, which has a larger front axle able to handle this size loader. You will expedite the wear on the bevel gear axle housing seals. Engine block and frame are the same between the two models, is the reason for the possibility... The l54-l6060 get another bump in bevel gear housings with same la1055 loader.
LA805 is meant for l3560-l4060 l4760-l6060 use LA1055. There are 3 front axle assemblies amongst this l60 series.
The l4060 up has the same engine, with varying tuning/turbo. I have had a few l60 series.
"edit, I just checked and confirmed the l4060 has a differing front ladder frame than the l4760. So no go...
Just source a la805 its a good loader, capable of picking up a pallet of fresh sod.
