        The fill plug on my Jinma 254 hydrolic resevoir is vented and I am getting quite a bit of hydrolic fluid coming out during use, is this normal.  Does not seem right to me and at best is very messy.  Secondly the drop rate adjuster under the front of the seat is causing problems.  I think I hit it getting on the tractor and close it down.  Caused 3 point hydrolics to not operate until I figured it out.  Since I do not ever use the auxillary hydrolic plugs, can I remove the adjustable device and just put a appropriate sized bolt in the hole to plug it?

        Thanks

          These tractors will piss out some hydraulic fluid when going up hills when the reservoir is full.  Inherent in the design.  You can modify the fill plug to hook up a longer breather tube to go up the ROPS arm a ways and beat the problem, several guys have done that.

          Nope, you don't want to replace that flow control valve with a plug.  It is necessary that it be adjustable to control the fall rate of different weights of implements.  There is a small Allen-head set screw on the side that will lock it in place.  Might have to scrape some paint to find it.  Set it correctly for the weight of your implement and then lock the set screw.  If you just use a plug, it will be wide open all the time and your implements may come crashing down and  be damaged.  Bad idea generally, and really bad with ground-engaging implements that might then damage the lift mechanism itself.

            Thanks, brought my fill plug home and pulled off the breather.  Do you know what the thread size is for the breather stem in the top of the fill plug.  I got a small 1/4 inch male flare fitting to screw in nicely, but seems strange.
