The articulated wheeled skidder is an important component in the primary transport of timber In South Africa. Unlike agricultural tractors, wheeled skidders are specifically designed to winch and skid trees from the point of felling to a landing site. They are heavy, robust machines, with their centre of gravity positioned well forward. The power to weight ratio has been chosen for efficient performance when skidding trees.
Main factors influencing skidder productivity are:
• Skidding distance
• Bunch size (felling operation)
• Terrain (travel speed)
• Grapple and engine capacity
• Operator decisions
