There are a couple low-tech issues that can happen with the HST linkage that won't cost anything to fix, and they happen often enough I'd be inclined to think it's one of those problems and not the neutral detent (never heard of that failing). Not only is there an adjustment, but there's a damper (which slows the rate at which the treadle returns to center) that can start to bind and stick and hold the treadle in either direction. And then there's also the possibility that the cruise control mechanism (pawl/detent usually) is causing the problem. That one is tied into both the HST and brake linkage, and can give some oddball symptoms.
I had the damper get sticky on my B2920, which hampered the treadle from returning to center (made it very slow to return). I also had the cruise mechanism get sticky, which was holding the HST treadle one way or another. Every time I'd use the brake it would advance the cruise pawl and eventually start tugging on the HST treadle linkage. Both issues were easily fixed after I studied the linkages and mechanisms and found out where lubrication was needed. All of this should be visible from under the tractor so I don't think the presence of a cab should change things too much.
