The Grand Ls do not come with any rear remotes as std equipment.
No, Kubota has not addressed the poor quality of their rear remotes on their tractors. If anything it seems as if it has been getting worse over the last few years. This may not be the case, just that now more people are aware of the problem.
I would say that 1 of the reasons to have rear remotes on these tractors is to operate a top & tilt set. This really applies to people that do a lot of grading. The other reason is for all the various implements that can now have hydraulic actuated adjustments as an option.
Trust me, once you start making adjustments hydraulically, you will never willingly go back to manual adjustments.
A rear remote with the float feature is just like your loader valve with it's float feature. Put the valve in the float mode and the cylinder can move in and out on it's own allowing an implement to follow the ground contour just as you would do when back dragging with your loader.
Depending on what exactly it is that you are using the remote for, but there are several tasks where it is beneficial to have the double acting valve with the float feature. The only deterrent to having a valve with the float feature vs a simple double acting valve is the cost. A float featured valve operates as a double acting valve, with the float feature added.
If money is not a factor, I would suggest getting all 3 rear remotes and get all of them with the float feature if Kubota will do that. If not, at least 2 of them with float.
One other thing, if you may have any reason to need a grapple for your loader to move brush, logs etc, consider getting the 3rd function valve for the loader now. Dealers typically will give you a better cost with the original purchase vs getting any of this stuff later on.
Just my :2cents:, good luck with the purchase. :thumbsup:
