logging HeroesThE liTmuS TEST Of mayThe sun has reappeared after the rain, and the day is as beautiful as it gets when we head off to visitSAC's Viksjö team. The team is performing final felling with a new <strong>PONSSE</strong> Ergo harvester andBuffalo forwarder on the northern side of Lake Skälsjö, near the village of Ljustorp.38Ponsse <strong>News</strong> 1 • <strong>2011</strong>
logging HeroesAfter the sleety overnight rain, the ice-glazed forest road is slippery,forcing the driver to proceed with intense concentration."The road is slippery and slushy. The bottom is a little icy, but theground is not yet frozen. This can happen at the start of the season,"says Emil Flordal, who is operating the forwarder this morning. Theteam started driving Ponsse's machines in May 2008."We perform both thinning and final felling. While the externaldimensions of <strong>PONSSE</strong> forest machines are quite small, they'reequipped with powerful engines and their load-capacities are high,"says Emil.a NEW ExPEriENcENone of the team members had operated a <strong>PONSSE</strong> machine before,but everyone wanted to test the new forest machines because they hadheard they were reliable and efficient, capacity-wise."Even though it might be a little early to say, given that brandnew machines aren't supposed to give you trouble, it looks like therumours were true. We are happy and content with the choice ofmachines," says harvester operator Nils-Göran Viklund. PhilosopherRené Descartes is known for his proposition "Cogito, ergo sum", (in<strong>English</strong>, "I think, therefore I am")."If Ponsse's founder Einari Vidgrén named his first machine aftera clever dog, does the name Ergo have its roots in the machine's fast,smart and efficient information system? Learning the new menuswas relatively effortless and by now their use is easy," says Nils-Göran,whose work efficiency has increased. Although, for the most part,everything has been positive during the first season, one change waseffected after the new machines arrived.mOrE liGhTS"I thought the visibility insufficient, since the crane is in the front insteadof where I was used to it being. I wanted more lights because thevisibility during thinning was poor, particularly to the sides. Lampswere added and after that the convenience of the crane's new locationcompensated for the poor visibility.""The crane being located away from the cabin creates betterworking conditions and reduces vibration. On top of that the cabinis roomy and of a high quality. Driving comfort is furthermore increasedby the machine's suspension, which keeps the cabin leveldespite rugged terrain."a GOOd harVESTEr hEadNils-Göran is very happy with Ponsse's new H6 harvester head. Forone thing, the needlessly long hydraulic hoses have been shortened."The harvester head works fantastically well, it's fast and its measuringaccuracy is excellent. It's handy in both thinning and final felling,"says Nils-Göran. The feed speed, which is as fast as 6 m/s, the64 cm opening, the tilt's broad movement range and precision steeringare features that should please even the most seasoned harvesteroperator. Since the machines are equipped with efficient engineswhile having relatively small external dimensions, the team can carryout both thinning and final felling."Small BuT POWErful"The machines are small, but they have big hearts," says Emil Flordal,who has pulled his forwarder over by the side of the road leading upto the storage site. He likes the fact that there is plenty of horse-powerbeneath the hood. He attributes the machine's strength and efficiency,accompanied with previous levels of fuel consumption, to thehorse-power. The forwarder's load-bearing capacity is 14 tonnes andits engine size, 270 horse-power, equals that of a harvester.Ponsse <strong>News</strong> 1 • <strong>2011</strong> 39
