Forestry.com has visited Alstor in Dingle, Sweden, a company that, among other things, is manufacturing the popular mini-forwarder Alstor. We received a history lesson, a visit to their factory and the opportunity […]
The 70cc chainsaw segment is on fire! Both Stihl and Husqvarna is now shipping out one new chainsaw each in MS 462 for Stihl and 572XP for Husqvarna. These new chainsaws are going to ramp up the whole segment but […]
Very nice well done video. The aerial drone shot was great!
First faller with the 462 needed to do some work on his chain. It was sharp enough but just needed better depth gauge or cutter side plate settings.
The second tree felled by what looks like a pro who cuts wood daily for a living was smooth operating the 462, used his helmet screen and had a good cutting properly set chain on the saw.
The C85 chain sounds interesting and I hope we get them in Canada soon.
Thank you Willard!

Mossfeldts Skogstransporter in Ekshärad was the first in Sweden to operate a Canadian Tigercat 1085C. Their first 1085’er has now been running for over 2000 hours and their second one is newly delivered. Fo […]
So, we got our hands on a pre production Husqvarna 572xp. The purpose was to test it out and give the new chainsaw a first review.
To make it properly we hired a professional logger that now has tried out the […]
Great you’re happy with the 357.
I have one myself since like 10 years. I like it too, not modded as yours though.
Right now it does not work, it chokes when warm. Brought to a neigbour of mine and he shall have a deeper look at it.
It seems like some have had problem with the automatic decompression valve, does yours have that?
Have a…[Read more]
The 70cc chainsaw segment is on fire! Two new powerhouses released the same summer. Stihl MS 462 is a new 72cc Pro chainsaw that would like to give Husqvarna 572XP a match. At Forstmesse Lucerne we got to meet the […]
On Thursday, August 17, 2017, Husqvarna will reveal their latest chainsaw, probably it will be named Husqvarna 572XP. There is a lot of buzz right now, before the release and we thought it would be a good deal […]
It kind of amazing to see how simple, yet effective, protective clothing like chainsaw trousers or chaps actually works. A chainsaw is built for cut wood with efficiency, unfortunately, it works pretty well in […]
A new entertainment show called “Duellen” will start on Swedish public television in August 2017. The idea behind the show is that two competitors run duels in different crafts. One of the duels will be who cuts […]
A video showing a cruel Chainsaw Prank in Trondheim, Norway is currently viral. Tom Daniel Hansen Sylte pranks his friend so hard it causes him to faint.
Maybe this is taking prank to far, or what do you think?

Exactly Martin, thanks for the comment!
With 17.681 seedlings planted in 24 hours, Timo Kloft now claims a new world record in forest tree planting. The record attempt took place near Malå in the north of Sweden and was done with containerized conifer […]
Or, happy summer solstice to you!
It’s quite funny, it should be mid-summer by now but personally I’ve always felt that midsummer is in the beginning of the summer.
Today is a public holiday and a big day in Scandinavia where we celebrate the midsummer.
Wish you the best!
Fredrik Reuter wrote a new post, Komatsu SmartFlow – New Hydraulic System for Forwarder 9 months ago
Komatsu Forest showed its new technology SmartFlow for forwarders at Elmia Wood 2017, we received a review and a test run, watch the video further down.
SmartFlow came a little in the shadows in Komatsu’s feed […]
I have been in unofficial contact with a Komatsu employee about this. He claimed not to know all details but said that the valve in use is a standard Parker directional valve. They are also using hydraulic cylinders with precision position transducers (sensor).
The valve is a said to be a regular spool valve. The common way to use a spool valve is to let the one single spool control both the meter-in pump flow to the hydraulic cylinder and meter-out return flow from the hydraulic cylinder.
To get better control over the meter-out return flow from the cylinder, which many times is affected by crane inertia and weight of the load, Kamatsu is according to my source, using one separate spool valve for meter-in pump flow, and another separate spool valve for the meter out return flow. We can call this independently controlled flow metering. With this system, the cylinder speed and motion of the crane can be better controlled, and also minimize throttling energy losses over the valve orifice.
Eaton has already, 2016, introduced this type of valve CMA, with independently controlled flow metering. It means that each valve section has two separately controlled spools which also has position transducers for more exact flow metering. On top of that, each work port each has a pressure transducer.
This image shows the principles of Komatsu’s solution (not publicly verified), the standard way of valve connection and how the Eaton CMA valve connects.
So how all this will come out we will see around the 1st of September 2017, at the time when Komatsu plans to introduce forwarders with the SmartFlow system
