On the base of the tree types of ruts on soil combined with the behavior of lumps of soil when they are thrown against any surface, the Bavarian State Forest BaySF has developed a practical reference sheet:

•       If you have the type 1 and the soil lump is stable, you may drive.

•       If you have the type 3, then stop driving immediately

•       If you have the type 2 and the soil lump can be formed easily, you should try to drive very carefully:

--      if the ruts stay at type 2, then go on driving

--      if they turn to type 3

---     reduce the load or the tire pressure and repeat the test

---    if they still turn to type 3, then stop!

The word derives from Latin „procedere“, meaning “to go on”. As a term, „process“  describes what happenswith details about tools and machines, working steps, time consumption, results etc.

As soon as there is any normative implication how the process should be, we talk about a method. When this method should normally be used, we call it standard method.

In detail, we can make a difference between the terms working method, operational method and manner of working.

Processing changes the state of the working product. In forest harvesting context, processing includes delimbing, topping, cross-cutting or bucking and chipping, but not felling. Felling and processing together are called harvesting (in a narrower sense).

(See more at TDiv PR1-B01)

The processor is a self-propelled machine which is designed to delimb and cut-cross felled trees into logs (buffer 31 to 33 or buffer 32 to 33). Alternatives which are commonly used in forestry for the sub-processes of delimbing and cross-cutting are the chainsaw as a tool, and the harvester as a machine.

The processor can handle multiple functions such as delimbing, measuring and cross-cutting or bunching, but the processor cannot fell trees. Therefore, the work of the processor follows the felling of the tree and is mainly performed on central places, where full trees are arriving, or on the forest road.

Processors were the technical stage before industry was able to build harvesters, Today the task of a harvester can be done by harvesters as well. Only in combination with cable yarders, we se specialized processors.  

The work with the processor is assigned to the mechanized (automatic) work.
