A new harvester for the cost of a used one

What’s the cost of a used harvester that’s been run hard for 14,000 hours? That was the benchmark used when Kranman developed a harvester aimed at DIY forest owners. The result was presented at SkogsElmia.

The machine comes in two versions, the 520S and the 620S, and had its world premiere at the fair. Kranman is sticking its neck out by calling it the world’s first harvester for woodlot owners who actively manage their forest holdings.

“This is a group that currently buys used professional harvesters and gets a heap of problems thrown in for free,” explains Magnus Johansson, who helped design the Kranman machine. “We’ve chosen to make a simple, stable machine that starts and does its job when you go out on the weekend to do some thinning.”

The result is a real harvester in a smaller format. The newly developed crane is equipped with parallel linkage, and at the crane tip is a Jobo harvester head customised to Kranman’s specifications. It can handle trees with a root collar diameter of 30 cm, which means that the machine is suitable for doing first and second thinning. It also includes a basic measurement and control system that keeps tabs on diameters and lengths.

The difference between the two versions is that the basic model, the 520S, has a petrol engine while the 620S runs on diesel. The latter also has more equipment.

“Even before we calculated the price there was a lot of interest, and that’s grown here at SkogsElmia,” Johansson says.

Kranman has previously developed a hybrid machine but experience shows that using two machines – a harvester and a forwarder – works better. The forwarder, called Bison, is already on the market.

“Our goal was a new harvester for the same price as a hard-run used one costs,” says designer Magnus Johansson.
