Hi all, I'm a new member and new to skidsteers. I bought an old 753 with a genuine 1600hrs on the original engine pumps etc. I'm sure that there has been similar posts previously but I am having trouble searching them out. I have good drive strength (spinning wheels when against an immovable object) but I find that when I pull the sticks to the rear that the left side seems to not drive until I reach near the end point of the stick travel or I push forward on the left and then quickly to the rear. I assume that it is perhaps some kind of sticking valve?? Could someone please point me to previous posts or point me in the direction of possible causes that I can investigate. Thanks in advance
