Hello all. I searched but have not found answers to my quest. I am borrowing a buddies 743, and the last time I was working, the hydraulics when driving were not smooth.. "bucking" I believe is the term. Searching has suggested that the hydraulic fluid may be low, and there is a "looking glass" (or dipstick) on the left side while sitting in the cab. I have not been able to find the "looking glass". Can you please help with specifics where it is? I am starting to wonder if a past owner painted over it. Thanks Don
