I really do not know much about forrestry machinery (though Scandinavians are supposed to i guess...), but I have seen these Log-skidders that are used in some parts of the world.
I know they are no longer used in Northern Scandinava, but have been in the past and I have read about a few cases were such machines have been converted to articulated agricultural tractors. (Such as VolvoBMs old Farming-lisa prototype from the past, see prototype section of this website)
What is the main differences between Log-skidders and ag-tractors. It seems it would be a fairly easy conversion, but then one would hear of it being done more often.
Any ideas?

Hey Laapa, The ZTS Trstena forest skidders (with Zetor/ZTS engine, why else would i know of them??) have the option of a factory installed 3p hitch. www.ztstrstena.sk |

I've never been very interested in logging machinery except maybe for the cats. Some of those old IH crawlers like the TD 8 (Renze had the site from the Polish based company posted earlier) were popular when the industry went to smaller crawlers. What I have noticed about skidders is that they're built for being bumped, hit, or rolled. They're as high as possible under the axles to provide for clearing stumps. If one would convert one for agriculture, you would have to put on a hitch system and drawbar. The operator's platforms are built for roll overs. Some don't have a steering wheel, but use a stick like an airplane.Not sure why. Gearing might be wrong. I really don't know what they use for transmissions. Old time cats had different gears for construction than for agriculture. I supposed one who was a good mechanic and fabricator could convert one pretty easily. I do know that a southern company, Franklin, also offered a smaller skidder as a four wheel drive. I don't know if it had any success. Probably not. Now it seems that they're going to equipment that cuts and processes the logs for hauling in one process. I lived in two different locations in earlier days where logging was a major industry. You never saw any of that equipment working as it was used way in the back country. I would never want to be involved in that very dangerous occupation. Here is a site I found with some history. Interesting some of them are build by Wagner, The company also build the Wagner tractor which was partly predecessor of the Big Bud and Rite. www.vannattabros.com/skidder0.html |

The ZTS trstena skidders have a Praga 4 speed automatic with torque converter. That gearbox is also used in city buses over 360 hp, so in a 150 hp skidder they will do fine, even for tillage.
