Emil,
That's a nice looking beast. Where's the sawmill at?
When it first starts up the front of the machine raises up, how does that work? Never seen one of those before.

[Emil Nyman]

Its built by the swedish Massey Ferguson importer. Engine, gearbox and rearaxle is a MF 165. The frontwheel arms is fastened in a point near the rearaxle. The arms is operated by hydraulic. their is also an pipe betwen left and right so when one wheel is climbing on for example a stone the other whel goes down.

There was also a swedish company that builded similar machines on Ford 5000 chassies. Another company was Volvo/ÖSA. Their was also built a small amount of machines built on David Brown shassies.

I hope you understand my bad english. If not , let me now and i try again.

Emil,
Those look like rubber tyres. Can it run without the tracks?
Nice flick,

[Emil Nyman]

Yes its possible to go without tracks. The traks are the same type as "halftrack" but a little bigger.

Great videos Emil.
You don't need much power to use the crane.

[Mark]

Emil,
Your English was very good.
What do you do with the logs? Do you have them sawed into lumber or is this firewood?
Looks like fun to me, going through 3 feet of snow.

Like Henk has said already she doesn't need much rpm's to use the crane.

Yes its possible to go without tracks. The traks are the same type as "halftrack" but a little bigger.

How do you steer without tracks? By using the front wheels as usual, or by differential steering with back wheels?

[Emil Nyman]

The steering is powered by two hydraulic tubes betwen the tractor and the trailer. Its called "midsteering" in sweden. Its the same with or without tracks. Its also possible to steer by brakes when driving without the trailer. But just now my master brake cylinder is broken. Does anyone now where to by "Mico" brake cylinders?

I have a litle sawmil. Its an sawchain powered by a 4kw electric engine. I can put up a picture on it. The smal logs end logs with poor cuality i make to firewood or sells to paperindustries.

That is an interesting way to steer. Are the front wheels fixed in the straight ahead position?

Please show us some pics of your saw mill. What sort of trees are you growing?
All the best,

[Emil Nyman]

Yes the frontwheels are in a fixed position.

I have ca 50% pine 40 spruce and 10% birch on my land.

I couldnt find any pictures in my computer but i had some pictures of my fathers sawmil. Its the same type but mine has electric feed on the sawmil(i dont have to push it forward). My fathers sawmil was sold by Jonsered and mine was sold by Husqvarna. Now the manufacture sells it by them self and its called Lenartfors. They also make an litle machin they call "the ironhorce. My father have one of this.

Wow, great flick, Emil!
Keep up the good work.

Very interesting thanks for posting. Are the hydraulics running from a crank mounted pump or the original tractor hydraulics? I to was surprised how quick it all seemed slow engine revs.

Do you stabilise the machine by dropping the nose onto the ground? I also notice that you appear to ajust the height of the tractor to axle whilst you are manoeuvering.

Am I unsterstanding that steering is effectively articulated/pivot by hydraulic rams between the tractor and the trailer?

Sorry for all the questions.

Great videos (did you do it all by your self with static camera?)

Thanks Peter

ther is a double front(crank) hydraulic pump. One pump for the crane and one for the steering, tracktensadjusting and heightadjusting. The tractor original pump is used to operate two hydraulic tubes betwen trackor and trailer. They prevent backflipping and make it posible to adjust the weigtbalanc betwen the front and backwheels

In one sequence in the flick a get stuck on a stump and i raised the front to get free again.

You have totaly right about the steering and and the way i made the video. I cut it in windovs flick.

Dont be sorry for your questions. This is a very nice way for me to train som english

Wonderful videos-thanks for sharing them! Out of curiosity, how many hectares do you operate on? I ask because I wonder if I have enough land to justify a setup like this one. Thank you!

Neat machine. Somewhere around here I have a Book on MF machinery and I was really amazed at all the stuff that they produced around the world. Some of the machines were very large. Around here we only see a few backhoes and a lot of old farm tractors. I have a MF 30D Backhoe/Loader and it has been a very good machine. Dandy Dave!
