Workshop Details

• Removal of leaning, broken, and hung up blow downs is a reality of trail maintenance.
• Traditional methods of cutting section by section are relatively dangerous as the sawyer is under the unstable and often unpredictable tree as the cutting is done.
• The use of rigging gear removes the operator from the danger area as the tree is brought down.
• Rigging gear is light weight; a two person team can carry the necessary rigging and saw gear.
