The five disciplines

The World Logging Championship consists of five disciplines. We borrowed Arjen Essenstam from the Dutch national team to tell us a little bit about every discipline and the strategy for each one.

 

Tree Felling

 

Fitting another chain

 

Bucking with combined cuts

 

Precision bucking

 

Limbing

To fell a tree

The most self-evident discipline in the World Logging Championship must be Tree Felling. There are a lot of points at stake in this precision task, not to mention the amount of prestige. The discipline has been a part of WLC since the start and has since then been altered to become as fair to the participants as possible. In the early years of the competition, the material consisted of real trees out in a forest, adding a lot of factors to the estimations of the discipline execution, like wind and gradient. Now, completely straight spruce tree trunks are dug down in the ground on an open field, excluding most of the external impact.

 

A brief look at the discipline rules

The goal is to hit a target point with the felled tree, placed at least 15 meters from the spruce. The discipline score is set by three different measurements: distance between the spruce and the target, the quality of the cut and the time exceeding three minutes. This means that it doesn’t matter how fast you execute the discipline, as long as it’s no more than three minutes total. Therefore speed is of a lesser matter than in other disciplines.

The diameter of the trees can be between 28 cm and 38 cm, but the total difference between the trees cannot be more than 4 cm in one competition.  An ideal cut is performed as the image below indicates.

Strategy

As already stated, you don’t gain any point by performing the discipline as fast as possible, as long as you don’t exceed the three minutes deadline. There is not an optimal chainsaw for this discipline; the more important thing is to make sure that your machine is calibrated correct and that you have taken all safety measures before you start the felling.

The history

The Swedish logger Lars Strandell has competed in 14 World Logging Championships so far and is definitely one of the most experienced participants in the world. In the WLC held in Norway 2000 he set the unbreakable world record of 660 points, the highest score possible. In 2006, the excellent German logger Gottfried Schädlich though shared the record by just like Strandell performing a perfect score.

Since the exclusion of felling real trees in a forest, the Nordic domination of the discipline has been terminated. Nowadays it’s hard to find favorite participators to win, though Germany, Finland and Russia has performed very well in the last championships. This year it is going to be more thrilling than ever in this discipline, so please keep an eye on the Husqvarna Logger Blog the whole weekend to not miss out on anything of what’s happening down in Zagreb on the 23rd through the 26th of September.

The Art of Limbing

The limbing discipline is and has always been the last part of the championship. It is also maybe the most exciting and entertaining discipline out of the five. We would like to give you an elaboration in the discipline to let you know more about the rules, the strategy and the history.

Limbing a tree is where you get rid of all the branches sticking out from a tree bole. If done by hand, this is most effectively executed by using a good chainsaw. A well-performed limbing leaves a bole without any deep cuts of pieces or branches left.

 

 

A brief look at the discipline rules

The limbing discipline is judged on a time-based score. If not performed perfectly, the judges can give out penalty seconds. Over 5 mm deep cuts or 5 mm left branch pieces give the participant a penalty. The winner is the one limbing the bole fastest, without any mistakes.

There are 30 branches to be limbed. These are divided into nine different branch segments, where the branches are attached to the bole in specific angles. Every branch is 30 mm thick and the bole is 140 mm. The length of the bole is six meters. Below you see a chart over the nine different segments.

 

 

Strategy

When competing in limbing, it is important to be fast, to be precise and to always have a safety focus. It’s like competing in slalom skiing, you have to memorize the course and find a rhythm to perform as fast as possible. You always have to know how you to from one branch or one segment to another the fastest possible way. Saw angle and footwork are two important factors and it’s important that you let the chainsaw bar follow the bole as close as possible, so that you don’t get any penalty seconds.

A mistake made by many less experienced loggers is the prioritization of speed over accuracy. Every second is worth 4 points in the final score and a mistake gives you a 20-point penalty. It is therefore worth it to go back and “re-limb” a branch if you didn’t make it perfectly the first time. Let’s say your second attempt takes you two seconds, you still gain 12 points by doing it.

 

The history

The limbing discipline has been a part of the WLC since the beginning in 1970. The world record is 456 points and was set by Vadim Imankulov from Russia in year 2006. Russia is not traditionally one of the strongest nations in the discipline. The strongest nations over the years have been Austria, Italy and the Scandinavian nations.

If one logger should be mentioned especially, it has to be Gottfried Schädlich from Germany. He did for logging what Jan Boklöv did for ski-jumping and what Richard Fosbury did for high jump. He invented a new way of footwork, which is now heavily used. He started to jump from one segment to the next in a kind of weird looking but effective way. Schädlich himself described the new style as “schnell aber nicht schön”.
