Here's the story on this on how our '99 Lamtrac met its maker 3 years ago..........
Well I guess a picture is worth a thousand words, so here's the picture of our groomer that the operator bailed out of in a flash, and he's a big boy, no injuries other than his pride. The machine stayed there for 2 nights before we could get salvage equipment in for the retrieval, by that time the unit was froze pretty solid in the creek, most all the damage was done when we had to haul it out.
Well as you see the spot where the groomer went down was a tight bend in the creek, our policy is any water crossings you have to drill a hole in the ice and if you don't have 18 inches of ice you don't cross,the operator stopped at the bank of the creek drilled his hole he had aprox 24 inches of ice, about 20 feet to the left of where he actually went in, when he crossed he went over to his right believing it to be ok, he had gone over that spot aprox 5 times already this winter, however, where the tight bend in the creek comes in to play is that the current makes a sweep at that point and wears the ice much more at that spot, the water level had dropped considerably in the previous weeks of his crossings, leaving a space between the water and ice, he had unhooked his drag built a snow bridge at his crossing point just to be more safe drove over it 2 times with no problem, hooked up the drag and attempted to cross, so the previous 2 crossings weakened the unsupported ice with the drag in tow, the ice could not bear the weight. Where he went through their was only 8 inches of ice because of the tight bend at that point in the creek, but because of the snow depth one would not be able to see that the creek took a sharp turn, and only 20 feet away the ice was 24 inches where he drilled his hole. So all in all there had been many factors that played a part in our groomer's demise the operator was at no fault. He has a new nickname now we call him "Bubbles".
I wasn't the operator that day(thankfully). I did meet up with him just before that happened and gave him an ice auger to check the ice thickness.
