My understanding is that the l5460 does not come with any rear remotes. I ordered 3 sets, two double action and one floater with detent. And I ordered the front 3rd function valve to use with a grapple.
So total of 4 hydro hoses sets (of two) counting the front.
One cool thing about the kubota rear remote parts is that they are modular and can easily be added to later (at least to three). Bolt ons with longer studs. Pricey, though.
