My B3200 3pt has a hesitation at the top couple of inches. When you pull the lever to lift the arms it lifts fine until a couple inches from the top and than it feels like the lever is being pushed back to neutral. If I let go and pull a couple times it will top out as it should. This is something new as I've had the tractor a year. I checked the hydro fluid level and its fine. FL works fine, no hesitations at all. Any thoughts?
