Snow Blower

The snow blower is a machine attached to a D4. Normally this is bolted onto the front of a bulldozer, but our D4s were too small to handle the weight. The simple solution was to chop the snow blower in half & bolt half on the front of the D4 and half onto the back. This balanced nicely, creating a very useful tool in a place where the snow accumulates around everything, all the time.

The business end of the Halley snow blower This is a close up of the business end of a snow blower. This is, basically, a D4 bulldozer with a big screw blade fitted to the front. It chews up snow, shovels etc & spits it (them) out of the spout at the top. A very handy tool, bearing in mind the amount of snow we had lying about the place.

Here's the snow blower in action. It's an excellent way to dig a big hole. This hole was used to take a profile of ice cores for density versus depth measurements. The scientists thought I'd dig a 4m deep hole, wide enough to operate a metre long ice core drill with a shovel, but I had a better idea and the tractor mechanic needed to test the newly serviced snow blower.
