– grinding of logs into chips for engineered wood, mulch, paper, or fuel Cut-to-length logging (CTL) – an expensive but efficient system where trees are felled, delimbed, and bucked to scale directly at the felling site Cable logging – skidding using a wire cable attached to the felled trees, most common in areas with steep topographic relief, variations include High lead logging – a cable is anchored to a tree at the top of the hill: Skyline logging – a carriage is used alongside the main cable to provide leverage Shovel logging – transport of multiple logs close to the logging road using a stationary loader, often used to minimize soil disturbance Heli-logging – transport of logs from the forest to the landing via helicopter, most commonly used in inaccessible areas or to minimize impact on the soil Log driving – transportation of individual logs on a waterway to a mill or port downstream Timber rafting – transportation downstream of multiple logs bundled together into a raft, considered less dangerous than log driving Harvesting tools Timber felling tools Hand Axe – primitive tool used felling and splitting Chainsaw – portable mechanized all-purpose saw, the most common tool used in hand-felling Crosscut saw – saws that have teeth that are designed to cut wood at a right angle to the direction of the wood grain, used for felling and bucking Bucksaw – a type of crosscut saw used by one or two people to buck felled trees into sawlogs Mechanized Feller buncher – vehicle with an attachment that can rapidly cut and gather several smaller trees before felling them Harvester – first half of the CTL system, vehicle that cuts, delimbs, and bucks the logs "to length" Log transportation tools Ground Peavey – a traditional tool consisting of a wooden lever handle with a movable metal hook with a sharp tip, used to spear the log for handling and moving Cant Hook – tool with the same premise as the peavey but with blunt teeth-bearing tip Yarder – in cable logging, a piece of equipment utilizing a pulley system of cables to pull or fly logs from the stump to the landing Forwarder – second half of the CTL system, the vehicle that carries logs clear off the ground from the felling site to the roadside landing Skidder – vehicle that drags logs along the ground from the felling site to
