Wondering if anyone else who is running a 2588 has had any trouble with the rotor gearbox? Had the rotor alarm going off yesterday and after some investagating seemed like it did not want to stay in low range. Talked to service manager at the dealership and no one was available to come out which was not a big deal as it had rained enough to shut us down for the day. Mechanic came out first thing this morning and did some adjustments and tried again. First trip down the field it jumped out of low range tried it in medium and it seemed to stay in but the adjuster outside the cab door was sloppy when the lever was in a gear. Mechanic checked and all the movement was coming from inside the gearbox. Figured we're going to have to put a new gearbox in but mechanic had to talk to service manager so that's fine. Called him later in the day and he hadn't talked to local rep yet so fine called back a while later and local rep told him that they know they have a problem and don't have a solution for it yet. Apparently they changed to this gearbox sometime in the late stages of 2388 production. Wondering if anyone else has had this problem yet? Running in corn and rotor is now 100 RPM more than i'd like. Still doing an acceptable job on grain loss and sample but know it could be better.
