Unfortunately, no 3rd party rear remote kits that I am aware of get mounted in factory locations with factory-type levers, none.
As far as the hose requirements, there are so many variations that are possible that a lot of people would be very upset when half of the hoses that they had (if hoses were supplied) would not work. Thus no hoses supplied. I agree though, they sure should have let you know before you made the purchase that hoses were not supplied. Now there is a good chance that the dealer did not know this if it was the first kit of that kind that they sold. But then they should know either from experience or simply asking Land Pride themselves.
But to be honest, the person you made the purchase with most likely doesn't have any idea what is entailed for the installation and simply does not, or did not know to even ask.
If you could post pictures, that would be great.
It is my understanding that Kubota is still back-ordered on these and really has no idea when they will be available. This Land Pride option might actually be a viable option for some people with open station models and pictures are always good.
