I'm trying to help my dad with maintenance issues on his B3000HST, with cab. He's had it since new, and has about 450 hours on it, IIRC. The last time I was over working with him, I noticed that the machine seems to creep when it should be in neutral. If you fuss with the pedal, you can get it to stop, but the neutral band is a lot smaller than I would have expected, and system drag keeps it ever so slightly in gear. I inspected the linkage and greased the HST pedal pivot, and nothing seemed out of place. Everything worked, it just wouldn't quite completely center reliably. Based on that, I figure that the linkage has just worn or drifted a little, and needs some adjustment.
I came home to dig through the two versions of the WSM that I have (both multi-machine ones, B3030+, on e purchased, one found online) and was quite disappointed by what I've found. For what has to be one of the most critical and complex external linkages in the system, you get a business-card sized photo and a brief paragraph on its operation, and no real adjustment instructions anywhere to be found. Troubleshooting section said go to page 3-S13, to adjust the "neutral adjuster" which isn't even mentioned on that page, or any of the adjoining ones that I can find. I don't see anything about tuning the linkage and how much dead band should be there. With as many control rods operating as this system has, I would expect there's an "adjust this rod / system first, leave this much slack, then adjust that" hierarchy and tuning procedure, but if it exists, I can't find it.
Does anyone have any advice for this issue, or a source for a better set of instructions? If I need to get another version of the WSM, I'm not against buying it, but I don't want to dump more money into books that say (or don't say) the same thing as what I already have. Unfortunately, I don't have immediate access to the machine itself. I'll be heading back over next weekend to work on the machine, so hopefully I can get this resolved. As someone who frequently works as the ground-man alongside the tractor, having it creep when you call for a stop is quite disconcerting.
