I really suggest you change the hydraulic/transmission fluid plus the front alxe fluid. Daedong admits to putting UTF in front axle for convenience of using 1 oil plus it's a little lighter and help flush initial wear fillings out of the axle - better to put 80w-90 gear lube back in front axle (plus it cost less). Change the hydr/trans fluid for the same reason - to flush out any residual fillings that haven't "yet" gone into the filter. I don't think Daedong uses a very expensive fluid here because they intend it to only run the first 50 hrs. and get flushed.
The Bobcat fluid is more expensive. It is a very high quality multi-viscosity fluid, but if you don't wish to spend the $ for it check with the Kioti guys and see what their manual lists for approved fluids. Kioti is owned by Daedong so only "factory approved" fluids are listed in their manual, if using 1 of those there is no way Babcat could legitamately come back on you for using the incorrect fluid, if you did have some rare hydraulic failure.
