Combines Fore and Aft on 1460

yes it is possible as most of the 1400 series in the uk were fitted with a fore-aft kit, all you need is the extra section for the valve block, hoses and then wire up a switch.

Another unloading auger swing valve can be added on top of the original to power the fore_aft. Hopefully SD Man will step in here but I think he said a new valve through Case in around $1000 and used ones are hard to find. Some guys are adding the electric spitter valves for tractors after the unloading auger valve to that valve can run the unloading auger swing or the fore_aft, this might be the route we go as it would only cost $350.

Mine uses a single valve plumed into the unloading and works well. This way the switch for the auger unload works the f@a. Mounted in the storage compartment.
