Skidders, saws and trucks... many opinions and they all stink!
I'm partial to my manual tranny... partly cause I've never ran a skidder with a power shift. but then the Deere phsycho rage is a little different than the standared trannys is most manual skidders
A few names and by all means not a comprehensive list.
Timberjack now owned by Deere, old ones are off the shelf parts
CanCar/Garrett/Tree Farmer/Franklin, Garretts started it, they all pretty much use off the shelf parts, All names derive from the original Garrett licence, just made in various factorys and countries overt the years
Clark, heavy beasts that from all accounts are nearly indistructable
International, hard to find these as they didn't make comparitively many, but its still an international, also know as a houghs
Deere, the 440-540 skidders are everywhere and cheap!, the newer versions are like flys, parts on anything Deere can get spendy... (I own a 440a)
Mountain Loggers, These are an odd duck, powerfull well made machines, but a little rare, still off the shelf parts... they made one with a 6v71 detroit... ******* monster, 1" skid line breaking beasty... Really more of a regional thing, count yerself lucky to see one east of the mississippi...
Then there are the various tractor makes that never really took off, Masey Ferguson, Case, Allis chalmers, all made something resembling a skidder just not very many, Deer and Timberjack pretty much dominated, with garrett/cancar/franklin holding out for many many years (Garretts finally got sunk by old age)
Anyway they all have good points, just make sure you can get parts for whatever you end up getting, and that the winch works.
If I had it all to do again... And I had a choice of machines... I'd probably go with an older timberjack 200 series, with the funky off center super low slung cab. Or I would stick with the Deere, only get a slightly newer version with a turbo...
Then again I still have a feaky man crush for an old Garrett 15... v-4 ford power, gearamatic 9 winch, skinny little tires, slap stick steering...
As far as price, here you can get a decent machine for under 10k, sometimes closer to 5-6k. Not really skidder country
Don't be afraid to look for equipment out of state, shipping isn't to horribly bad to make a good deal not worth it.
