Sabertooth, Sorry work has me jumping right now. I have noticed that multiple hydraulic functions effect the power on my tractor. This is to be expected from a heavy somewhat low HP compact tractor. I was using my FEL to pull some posts that were cemented into the ground and was not real impressed with it. I noticed that sitting still my tractor will creep forward if the parking brake was not engaged. I put the hydrostat in neutral and seemed to get more out of the FEL. I adjusted the shuttle shift properly to resolve. My thinking is for you guys with power issues to look for any system controls that could be reducing the flow to the desired function of use, rear remote detent, shuttle adjustment ect. you can also buy a gauge and a QD male fitting and plug into the Loader or rear remote connection and watch the pressure at that point and the effects of the other functions on it. If a few of us do this we can establish some baseline data to evaluate our issues.
I have also used the Kioti forum for lots of info. I am happy with the power of my tractor but it does take some control coordination to make the most of it.
