MB-trac
MB-trac is a range of agricultural tractors developed and produced from 1973 until 1991 by Mercedes-Benz Group, formerly known as Daimler-Benz. It is based on the ''trac'' design principle for tractors and shares its drivetrain with the Unimog. Mercedes-Benz offered the MB-trac in light duty, medium-duty, and heavy-duty versions in four different type series: 440, 441, 442, and 443. About 41,000 MB-tracs were made by former Daimler-Benz, before the manufacture was sold to Werner Forsttechnik in the early 1990s, who developed the WF trac skidder from the MB-trac. MB-trac types and model family Naming scheme In total, four type series (440, 441, 442, and 443) and twenty-one different series-production types of MB-trac were made, with either ten or sixteen models, depending on whether the ''Turbo''-designated models are considered separate from the non-Turbo-designated models. The naming scheme of the MB-trac is mostly homogeneous, with ''MB trac'' followed by a number roughl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Skidder Tragschlepper WF-trac 0288
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 (or railroad cars or a flume), 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 (''cable skidder''), just like the old steam donkeys, or with a hydraulic grapple either on boom (''grapple skidder'') or on the back of the frame ''(clambunk skidder)''. History Early skidders were pulled by a team of oxen, 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 ...

Tractors
A tractor is an engineering vehicle specifically designed to deliver a high tractive effort (or torque) at slow speeds, for the purposes of hauling a Trailer (vehicle), 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 mechanization, mechanize agricultural tasks, especially (and originally) tillage, and now many more. List of agricultural machinery, 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. Etymology The word ''tractor'' was taken from Latin, being the Agent (grammar), agent noun of ''trahere'' "to pull". The first recorded use of the word meaning "an engine or vehicle for pulling wagons or plows" occurred in 1896, from the earlier term "traction engine, traction motor" (1859).

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.
