    No chance of feathering the right foot, it's full power all the way or you stop! It's a worry on 120 deg days with a constant eye on the temp gauges. ####, I sound like a worry-wart lol.

    @Ozdriver , just lock it up as you start up. Power dividers are actually stronger locked in than unlocked. And it'll be way harder to spin out 2 tires at once, compared just the one it takes when unlocked. You're actually doing more damage to the power divider by spinning that one wheel than you'll ever do running it down the road locked. I've spent hours and hours at highways speeds locked in, it won't hurt a thing.

    That's what your power divider is for man.
    Lock that thing in. !

    If I was pulling that kinda weight going that slow I'd have it locked in regardless.
    And you can go around corners just fine with interlock engaged .

    I've run virtually the whole winter with the power divider locked-in and often in the summer in the wet--especially when pulling Super-Bs (63,500 kg / 140,000 lbs), or an OS/OD load that I can't get all the weight I'd like on the drives.

    First time it ever happened with a train was last year on this hill when it was wet, otherwise never, except on dirt roads of course, but nothing dramatic like last year.

    Yeah, I knew spinning one wheel wasn't doing any good to the differential in that diff. Those spider gears are small when you look at them (not the crown and pinion of course)

    Oz, @Cat sdp told you right. Like @Hammer166 said, lock in your power divider on flat ground. Cat said to feather the throttle. You are thinking that he is talking about not applying full power. He isn't. I will rephrase it. You need to run high rpms to avoid spinning. If the engine lugs down lower than 1400, downshift. Whatever speed you can hit that curve at the bottom, be in the gear that will turn 1600-1700 rpm. As soon as rpms drops to 1400, downshift. If it's real slick, you may want to consider running the trailers uphill one at a time.

    Chains would be great.
