What can be said about the skidders of Canada?
I'm not sure what you are asking me. A skidder is a piece of logging equipment used by Lumber companies to help remove cut down trees (logs) from the forest. Some times this is still done by a team of horses or mules and a person in areas that are more environmentally sensitive where the use of mechanical equipment can damage the soil.
If you would kindly revise your question based on this information, perhaps I can provide you with an improved response.
