Determining Average Skidding Distance on Rough Terrain
Journal of Forestry, 1979Abstract A method has been developed for accurately determining average skidding distance and surface area as affected by roughness of terrain. The mathematical procedure is based on a geometrical approximation of sectors of circles and use of three-dimensional coordinate data from a topographic map. The methodology, applicable to tracts

Experimental verification of distance and energy optimal motion planning on a skid-steered platform
SPIE Proceedings, 2017Mobile robots operating in the field need to be aware of the terrain and use this information to select the proper motion planning modality. For example, in very benign terrain it might be desirable to navigate to a goal following the shortest path.

Abstract Logging operation leads to increased runoff and soil loss on skid trails. This study was conducted to evaluate the appropriate distance among water diversions in skid trails. Surface runoff and soil loss were studied on skid trails in Nav district (North of Iran) after each rainfall event. Two skid trails were selected in this study.

The Influence of the Skidding Distance on the Value of Damage done to the Surface Soil Layer in the Course of Timber Harvesting in Pine Thinnings [PDF]
, 2008 The requirement to apply those timber harvesting technologies which are the least damaging to the environment ought to be put into the management practice of the State Forests as a priority. In recent years, a number of research and implementation tasks have been undertaken in this respect.

A Case Study of the Impact of Skidding Distance on Tractor Operator Exposure to Noise
2016The exposure of a tractor operator to noise does not depend solely on the noise produced by the machine, but also on the working conditions, which are constantly changing in forestry. This research was conducted with an adapted IMT 565 DV agricultural tractor in a mixed stand of beech and fir in southwestern Serbia.
