    摘要: A soil or snow probe which incorporates a load cell in the probe head and also an accelerometer so that a vertical strength profile of the snow or soil can be established. The device does not need to be driven at a constant speed and can be manually driven into the soil or snow. The resistance to penetration is measured using a load cell which incorporates a low duro polymer selected for its ability to behave like a non compressible fluid. The device is portable and provides data quickly.

    摘要: A snow traction unit to replace a wheel of an all wheel drive vehicle which includes a frame supporting two carrier wheels; said carrier wheels being spaced apart a distance greater than their combined radii; an endless snow contacting track mounted for rotation on said carrier wheels; a track contacting surface provided between the lower extremities of said carrier wheels; a drive engagement means for engaging the drive shaft of the vehicle and for driving at least one of said carrier wheels; the arrangement of the width of the track, the spacing between the carrier wheels and the track contacting surface resulting in the vehicle having a force imprint less than 250 Kg/square meter.
