 A slip tongue log skidder used in the 19th and early 20th centuries. 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. Here they are loaded onto trucks, or in times past, railroad cars or flumes, & sent to the mill. One exception is that in the early days of logging, when distances to the timberline from 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/winch, just like the old steam donkeys, or a grapple or a clam-bunk.

History Early skidders were pulled by a team of horses or mules. The driver would straddle the cart over felled logs, where dangling tongs would be positioned to raise the end of the log off the ground. The team pulled the tongue forward, allowing the log to "skid" along between the rolling wheels. These were known as "slip-tounge wheels" Starting in the early 1920s, animals were gradually replaced by gasoline-powered crawlers, although some small operations continue to use them. In other places, steel "arches" were used behind the crawlers. Similar in function to the slip-tongue wheels, arches were used to reduce friction by raising up one end of the load, which was dangled from a cable which in turn ran down the back of the arch, & was raised or lowered by the crawler's winch. Another piece similar to the arch was the "bummer", which was simply a small trailer to be towed behind a crawler, on top of which one end of the log load would rest.

 Clyde Skidder at Marathon Logging Camp ~1921 The early mechanical skidders were steam powered. They traveled on railroads, known as "dummylines" and the felled trees were dragged or "skidded" to the railroad where they were later loaded onto rail cars. Some were just steam donkeys, others were more compilcated. One popular brand was the Clyde Skidder, built by Clyde Ironworks in DeLuth, MN. The Clyde skidder illustrated was photographed at the Marathon Lumber Company logging operations near Newton, MS in the early 1920's. Although these machines appear to be large and cumbersome, they were true workhorses of their day. The Clyde was capable of retrieving logs from four different points at the same time. Each cable, or lead, was approximately 1000 feet in length. Once the logs were attached and a clearance signal was sent for retrieval, they could be skidded at a speed of 1000 feet per minute. Working conditions around these machines were very dangerous. The largest of these was the Lidgerwood skidder, which not only brought logs to the landing from the cutting site, but loaded them onto railroad cars as well, making it both a skidder & loader.

Modern equivalents Contemporary skidders are tracked or four wheel drive tractors with a turbocharged diesel engine, winch and steel, funnel-shaped guards on the rear to protect the wheels. They have articulated steering and usually a small, adjustable, push-blade on the front. The operator/logger is protected from falling or flying debris (or parted cables, or rolling over) by a steel enclosure. U.S. M60 Patton tank. ...

On a cable skidder, the cable is reeled out and attached to a pull of cut timber, then the powerful winch pulls the load toward the skidder. The winch or grapple holds the trees while the skidder drags them to a landing area or other collection point for forwarding to a loading point near a road. logskidder on clearcut plot Image taken by me, released under GFDL Pollinator 05:34, 21 Mar 2004 (UTC) ( ) File history Legend: (cur) = this is the current file, (del) = delete this old version, (rev) = revert to this old version. ...

Alternately, some skidders have a hydraulic grapple claw instead of a winch, and the claw (on a boom) grips and lifts the timber. Most grapple booms are fixed in place (to lift only), but some models permit the grapple boom to be swung from side to side allowing spread out trees to be grabbed easier. Furthermore, some Canadian loggers have created a hybrid by adding a grapple claw to the push-blade of their grapple skidders. This permits hauling back bark and tops when returning from a "landing" to a cut block. Excavator. ...

The skidder can also be used for pulling tree stumps, pushing over small trees, and preliminary grading of a logging path known as a "skid road".
One disadvantage of skidder logging in thinning operations is the damage to remaining trees as branches and trunks are dragged against them, tearing away the protective bark of living trees. Another concern is the deep furrows sometimes made by skidders in the topsoil, especially when using tires with chains, which alter surface runoff patterns and increases the costs of forest rehabilitation and reforestation. Topsoil is the uppermost layer of soil, usually the top six to eight inches. ...
