Yes and no on hooking 'any' hydraulic implement on the FEL and running it off the FEL lever/stick.
You
can do what I just wrote extensively about in the following thread:

Note; I'm not that familiar with your particular Kioti model and what it comes with regarding rear remotes from the factory, BUT most anything can be done, and it's just a question of familiarizing yourself, mostly here on TBN, with what works best with what situations and needs for power. If you are going to run something that takes a LOT of fluid flow, tractors aren't as well equipped to meet that need, as are skid steers, for instance, BUT tractors can be fitted with aux tank(s) to allow for more fluid available and more flow to keep the hydraulic fluid within needed temp range, IF necessary.
Mostly though running a diverter valve off a second set of rear remotes to have QDs available up front on one's FEL will allow you to 'convert' the FEL lever to a real 'joystick' with trigger switch, like I describe in the above linked thread. This will allow you more control of what is going on up front, while two pairs of rear remotes will allow for most needs off the 3PH at the rear. I use the setup described in the linked thread to move my snowplow from the FEL arms, and my log grapple, opens/closes it's jaws via the 'joystick trigger. Same for my Sickle bar; it uses the trigger to move the bars cutters.
Hope this helps answer your questions...
