Short logs can be pre-skidded (dragged) by draught horses or mules

 

Functiogram

Advantages

• Capacity to deal with almost any terrain conditions 
  
• Limited impact

Limitations, thresholds

• Short distance only
• Animals need training and constant care
• Low productivity
• Only works with relatively small and short logs that are within the weight capacity of animal power

Main use

• Small scale forestry

Economic suitability

Example:

• machine costs without personal costs: 10,00 Euro/h
• personal costs per person: 35,00 Euro/h
• number of persons: 1
• in total: 45,00 Euro/h
• max. 0,4 m³ per log
• regression line minutes per tree
  • b₀ = 3,0
  • b₁ (tree volume) = 8,0
  • b₂ (skidding distance) = 0,025
