    My tractor was a 1976 model, built for Japanese drivers, six foot tall 200+ fat men need not try to jump.

    A better image than the Coyote cartoon character is to look at movies made of ships going down at sea. They always run opposite the roll, not towards itl. Wonder why?

    Absolutely, turning into a downhill is certainly safer than the opposite. If you have time. My point of going slow is to, in effect, speed up your brain focus on immediate events, i.e. more cycles per second devoted to what's going on. It's my contention that the bottom line on accidents is lack of awareness of what is happening. When some situation is perceived as dangerous increasing focus so that more of your brain is devoted to immediate events greatly increases your chances. I can tell you, when the old farmall was on two wheels that was all I was focused on 100%, foot at the ready on the clutch, etc. I've done some silly things (mostly when very young - how about driving from Sardis, Miss to Memphis, Tenn in 30 minutes; average road speed 120 mph) but the few accidents I've had ALL came from lack of attention to what was going on.

    Bird indicates the difficulty of leaping off a moving object. I wonder how many times he's done that?

    Again, the bottom line, in my view, is enhanced awareness between extrenal events and your brain modeling of those events. The better it is, the better your chances. Awareness reduces accidents. Obliviousness increases accidents. As far as "situations" leading to dangerous conditions, remember Newton's first axiom "Every body continues in its state of rest, or of uniform motion in a right line, unless it is compelled to change that state by forces impressed upon it." So it is with tractors, so it is with people. Everything.

    Read the whole thread........YES it happens before you can do THINK what to do.......the best thing as far as I am concerned is knowledge and PREVENTION......a slope indicator was mentioned once..........not to plug them; but R&B discussed heavily over in the Safety forum IS, for me, the only way to go..........It removes doubt and question from all work on a slope......totally worth reading and the small investment in your life.........GO slow and THINK........Dennis

    DennisArrow, on a slightly different note...
    As a fellow Iseki owner, do you have a ROPS/belt on yours?
    My wife is on me like white-on-rice to get one installed on mine. If so, who, where, how (much), etc.?

    Grim,

    Maybe even a better analogy yet would be those guys who run on floating logs.. running like mad with the log rotating under them. [img]/forums/images/graemlins/grin.gif[/img]

    I would guess, hever having seen it happen, that a big ship turns over a lot more slowly than a tractor would? This would give them time to get to the upper side, which of course is a better place to be if you can pull it off.

    Let's hope nobody here (or anywhere for that matter) has a need to test any of these theories!!

    Gotta agree with your ideas about slowing things down enough to give the brain time to process and focus more clearly. Of course with a HST you could accelerate quickly if necessary.. but on a gear trans you wouldn't have time to change gears, etc.

    Best,
    Bob

    <font color="blue"> What is a safe uphill slope for a tractor? Downhill the same as uphill? How about horizontally, what is a comfortable slope to traverse hills.
    </font>

    Never exceed the manufacturers recommendation. (now there's a weenie, no-sue-em answer [img]/forums/images/graemlins/grin.gif[/img]) Hard to say. As many people have answered, the angle can change very quickly if you hit a rut or rock and the angle can be irrelevant if the tractor's center of gravity is higher or lower than what the manufacturer tested at because of implements, weights, etc... My suggestion would be to get familiar with the machine on flat land. Go slow and build up your confidence, skill and familiarity with your machine and your work area. Practice safe work habits. Walk the areas that you intend to operate on before you operate. Always use the safety equipment no matter what. That means ROPS and seat belt at all times, every time, even just backing in and out of the garage. Roll overs can happen on flat ground too. You could hook something with a towed implement and over you go backwards before you can react to it. High speed turns can cause a flip to the side or roll over. I had my tractor going all out mowing about 8-9 MPH and started making turns. Wide sweeping turns. They felt very comfortable, so I started making each successive turn tighter and tighter just to see what would happen(I use to do this kind of stuff in cars too, just to see how they would handle). One turn too tight and I was up on three wheels. I pulled my joystick from float to lock(my mower is mounted on the FEL arms) and that tended to act as outriggers and I didn't go over. I don't know if I would have gone over had I not done this, but if I had hit a dip or rock at the same time I got up on three wheels, my guess(just a guess) is that I probably would have gone over.

    Another problem is, some people get complacent about safety and paying attention. How often have any of us been out mowing and just gotten into it and started zoning out? Down the field. Up the field. Down the field. Heck, you start thinking about other things, and before you know it the field is done and you wonder how you got there so fast. Were you paying attention the entire time? Try to remember when you passed that tree. Can you? That's why it is important to be alert and focused on what you are doing at all times. With a high level of focus and a familiarity with your machine, you will probably get out of sticky situations quickly and safely every time(you may not even get into sticky situations ever if you plan well). However, for those times that you can't you have to rely on your safety equipment. I wouldn't attempt a jump from a rolling tractor for anything. If you jump to the downhill side, you'll probably get squished. If you try to jump to the uphill side, you probably won't make it over the top but at least you'd have better odds going uphill than downhill.

    As for turning into the ditch if you detect a roll is eminent, that might just work. Hope your seat belt is on, because you'll be eating the hood when the front of the tractor meets the other side of the ditch. But that beats rolling and then lying submerged under water strapped in to your seatbelt, knowing you lived through a roll over but will drown in a minute or two. You probably shouldn't have been that close to the ditch to start with. Just stay away from them or get the proper equipment to mow them. Better yet, plant some ground cover and never mow it again. [img]/forums/images/graemlins/smile.gif[/img]

    Anyway, those are just my opinions. Thanks for listening.

    This has been a great discussion so far. Good questions. Good answers. Hope everyone takes the time to become familiar with their machine and practice safe operating techniques. Best wishes to all.

    Mossroad,

    On uphill vs. downhill jumping.....

    My instincts took over after the initial nano-seconds that followed realizing I was in a roll.

    The uphill jump, would have worked, IF the tractor had not been coming UP to meet me. Thus, my foot getting stuck in the clutch/brake area.

    I think If I would have went downhill, I would have been even
    more squished.

    But, instincts told me to go over the top. Something about that just seemed right. Sort of like falling, you don't jump into it, you kind of hold back, looking for something to hang on to.

    -Interesting eh?

    <font color="blue"> I think the best mind set is to believe there is no safe slope for a tractor!.
    </font>

    Absolutely right - you can roll a tractor on level ground. Over the 4th weekend there was a guy using his tractor to pull a float. After the parade he made a sharp turn too fast and rolled it. Killed him. Might have hit a pothole or something, but this was on a city street.

    Having said that, I regularly use my tractor on slopes that are in the 20+ degree range. Go slow, keep it low, and keep an eye on the tilt-meter. Also definately listen to your instincts and if you are concerned about being able to do something, don't.
