Kubota rx141

Hi all Have recently purchased an rx141 here in Aust. Im certain it is a Jap import. Trying to find out any information i can. In particular i want to add an auger drive. There is currently no pipe work for this however it looks as thought there is a spare port on the block. The machine has an offset boom so i was planing to run steel pipework up to the knuckle and then rubber from there. Any thoughts / suggestions? The offset boom is driven by a foot pedal on the right hand side of the controls. It looks as though there may have been a provision for another pedal for the heal of the foot as there is a slot in the metal housing below the seat that is nearly right above the hydraulic block. I will try and get some pictures to aid. The alternative to this would be to use the lines for the knuckle boom and put 3 way valves in to divert the flow from the knuckle ram to the auger. Thanks in advance.
