Logging is the process of cutting, processing, and moving trees to a location for transport. It may include skidding, on-site processing, and loading of trees or logs onto trucks or skeleton cars. In forestry, the term logging is sometimes used narrowly to describe the logistics of moving wood from the stump to somewhere outside the forest, usually a sawmill or a lumber yard. In common usage, however, the term may cover a range of forestry or silviculture activities.
A tractor is an engineering vehicle specifically designed to deliver a high tractive effort at slow speeds, for the purposes of hauling a trailer or machinery such as that used in agriculture, mining or construction. Most commonly, the term is used to describe a farm vehicle that provides the power and traction to mechanize agricultural tasks, especially tillage, and now many more. Agricultural implements may be towed behind or mounted on the tractor, and the tractor may also provide a source of power if the implement is mechanised.
A skid loader, skid-steer loader, SSL, or skidsteer is any of a class of compact heavy equipment with lift arms that can attach to a wide variety of buckets and other labor-saving tools or attachments.
A chainsaw is a saw that cuts with a set of teeth attached to a rotating chain driven along a guide bar. Modern chainsaws are used in activities such as tree felling, limbing, bucking, pruning, cutting firebreaks in wildland fire suppression, harvesting of firewood, for use in chainsaw art and chainsaw mills, for cutting concrete, and cutting ice. Precursors to modern chainsaws were first used in surgery, with patents for wood chainsaws beginning in the late 19th century.
A backhoe—also called rear actor or back actor—is a type of excavating equipment, or digger, consisting of a digging bucket on the end of a two-part articulated arm. It is typically mounted on the back of a tractor or front loader, the latter forming a "backhoe loader". The section of the arm closest to the vehicle is known as the boom, while the section that carries the bucket is known as the dipper, both terms derived from steam shovels. The boom, which is the long piece of the backhoe arm attached to the tractor through a pivot called the king-post, is located closest to the cab. It allows the arm to pivot left and right, typically through a range of 180 to 200 degrees, and also enables lifting and lowering movements.
A skidder is any type of heavy vehicle used in a logging operation for pulling cut trees out of a forest in a process called "skidding", in which the logs are transported from the cutting site to a landing. There they are loaded onto trucks, and sent to the mill. One exception is that in the early days of logging, when distances from the timberline to the mill were shorter, the landing stage was omitted altogether, and the "skidder" would have been used as the main road vehicle, in place of the trucks, railroad, or flume. Modern forms of skidders can pull trees with a cable and winch, just like the old steam donkeys, or with a hydraulic grapple either on boom or on the back of the frame (clambunk skidder).
A feller buncher is a type of harvester used in logging. It is a motorized vehicle with an attachment that can rapidly gather and cut a tree before felling it.
A steam donkey or donkey engine is a steam-powered winch once widely used in logging, mining, maritime, and other industrial applications.
Combined driving is an equestrian sport involving carriage driving. In this discipline, the driver sits on a vehicle drawn by a single horse, a pair or a team of four. The sport has three phases: dressage, cross-country marathon and obstacle cone driving — patterned after the mounted equestrian sport of eventing. It is one of the ten international equestrian sport horse disciplines recognized by the Fédération Équestre Internationale (FEI). Combined driving became an FEI discipline in 1970 when Prince Philip, Duke of Edinburgh, the then-president of FEI, produced the first rule book.
A semi-trailer is a trailer without a front axle. The combination of a semi-trailer and a tractor truck is called a semi-trailer truck.
The Washington Winch sits in the forests of eastern Victoria near Swifts Creek and is also known as the Washington Iron Works Skidder.
Various obstacles are found in competitive sports involving horse jumping. These include show jumping, hunter, and the cross-country phase of the equestrian discipline of eventing. The size and type of obstacles vary depending on the course and the level of the horse and rider, but all horses must successfully negotiate these obstacles in order to complete a competition. Fences used in hunter and eventing are generally made to look relatively rustic and natural.
Collier Memorial State Park is a state park in southern Oregon. The park is operated and maintained by the Oregon Parks and Recreation Department. It is located on U.S. Highway 97, approximately 30 miles (48 km) north of Klamath Falls and 105 miles (169 km) south of Bend. The park covers 146 acres (59 ha) along the Williamson River.
A log splitter is a piece of machinery or equipment used for splitting firewood from softwood or hardwood logs that have been pre-cut into sections (rounds), usually by chainsaw or on a saw bench. Many log splitters consist of a hydraulic pump or electric motor which then powers a hydraulic or electrical rod and piston assembly. Generally, these are often rated by the tons of force they can generate. The higher the force rating, the greater the thickness or length of the rounds that can be split. The log splitter consists of all four major hydraulic components.
Western Riding is a competitive event at American horse shows, particularly those for stock horse breeds such as the American Quarter Horse. It is not to be confused with the general term "western riding," referring to the many forms of equestrianism where riders use a western saddle; instead, it refers to a particular class where the horse and rider complete a pattern that incorporates elements of both reining and trail classes, but requiring horses to perform in a quiet style akin to that of a Western pleasure class. Horses are evaluated on “quality of gaits, lead changes at the lope, response to the rider, manners and disposition." While all three gaits are required, most of the pattern is performed at a lope. Emphasis is placed on the horse's smoothness, even cadence, and precise, clean flying lead changes.
The Lombard Steam Log Hauler, patented 21 May 1901, was the first successful commercial application of a continuous track for vehicle propulsion. The concept was later used for military tanks during World War I and for agricultural tractors and construction equipment following the war.
A driverless tractor is an autonomous farm vehicle that delivers a high tractive effort at slow speeds for the purposes of tillage and other agricultural tasks. It is considered driverless because it operates without the presence of a human inside the tractor itself. Like other unmanned ground vehicles, they are programmed to independently observe their position, decide speed, and avoid obstacles such as people, animals, or objects in the field while performing their task. The various driverless tractors are split into full autonomous technology and supervised autonomy. The idea of the driverless tractor appears as early as 1940, but the concept has significantly evolved in the last few years. The tractors use GPS and other wireless technologies to farm land without requiring a driver. They operate simply with the aid of a supervisor monitoring the progress at a control station or with a manned tractor in lead.
Forestry mulching is a land clearing method that uses a single machine to cut, grind, and clear vegetation.
The International Bus Roadeo is an annual bus driving and bus maintenance competition, or roadeo, hosted by the American Public Transportation Association. A grand prize is given to the bus transit system with the highest composite bus operation and bus maintenance score. The bus driving competition consists of an obstacle course. For the bus maintenance competition, teams of mechanics must locate and fix defects in a number of bus power trains and other systems.
Horse logging is the use of horses or mules in forestry. In the modern industrialized world, it is often part of sustainable forest management.
