Hi all, first time for me posting on the forum. I have a quick question. I have a Kubota L3400 that I want to add front and rear remotes to. The tractor has a backhoe and FEL. As I do not see my tractor model listed on the Summit website I'm not sure if the unit listed for the other Kubota "L" models would work. I contacted Summit and they tell me to use their universal unit. One other question. Both the universal and model specific units come with and without a joystick option. Is there an advantage of using that over a momentary switch? Since I already have power beyond hoses at the back of the tractor due to the backhoe, this should be an easy install. I apologize if I sound a little naive here. Thank you, Brett
