Can anyone identify this machine?

High track dozer?
No a dozer the sprocket isn't centered like the high track skidders are also they don't have the belly clearance. Here's a 527 swinger

I've watched a few videos of those 527's skidding, that looks like a real long day bouncing around in one of those.

Honestly they aren't that bad in the seat it also depends on the operator as well as who's cutting ahead of the yarding just like CTL running a forwarder.

 
Typically how I would set up a long log thin with a forwarder for pulp.

Ive always been curious about those.  What are the tracked machines strengths over a wheeled one?  Are these logs getting dragged from the harvester bunching to the truck with it?  How long of a skid?

Typically ground pressure, you can side hill some, as well as run much steeper ground a few local guys are tethering with a tigercat bogie skidder then another is tethering with a 527. When we thin with ours some of the skids are 1/2 mile so 2500 ft or so that's where a wheel skidder would shine.

Is the swing dozer also tasked with building roads or is there other iron for that?

Its refreshing to see some PNW action here!

A tracked grapple gets around good.

So I bought the machine, and the owner identified it as a C4 BG Treefarmer as you guys suspected. Also heavily modified with a reversed operator station. its got the ford industrial gas engine with 4speed trans going into the 2 speed transfer case with reverser (means 4 forward and 4 speeds reverse) also still has the pto output for the original winch thats not being used. Its got a 5 circuit valve bank for the hydraulics with 2 open circuits at the moment. Blade has been removed and Im unsure what the loader is from, possibly a full custom job but it works ok for now, might redo it in time. the grapple is too heavy for the machine so thats probably going to get sold. Everytime I run it I find something else that needs fixing but its a solid machine and at this point I don't feel bad about modifying it more. haha

Depends on the operations setup, we do some light road building with ours but it's really not setup to do heavy road building an issue is the blade, then the sprocket placement isn't in the best location for pushing the weight is pushed in the center vs rearward. We have an older D7F that makes a much better pusher as well as a good machine for pulling large oversize.

I wonder if at one time it had a shearer head on the front with the extra circuits.

Interesting machine, seems to go well with the stretch limo on a truck frame, looks like you will be riding in style on your way to the wood lot.

What makes you say the grapple is too big?  The lift rams look to be oriented very well for good breakout force but the curl cylinders are basically the opposite. 

Before you do any mods, toss a good pressure gauge into a tee on the main pump line and see what its relieved at.  Id be sure the pump is putting out what its rated for and if belt driven that its not slipping.  Then see if relief can be shimmed up to the hose rating. 


Id love to have that machine.  Woule have a 5ton military winch on the "back" powered by the vacant blade spools in the first week.  Skid and load with one tool... Beautiful.

Thanks for the suggestions so far everyone. Its not so much that the grapple is improperly sized but the issue is with the more with the actual weight of the implement. Its built heavy and extra steel has been added to make a makeshift rock screener out of it. Combine that with the wonky mounts and bad geometry and those hyd cyls are working hard. Oh i thought it would be wise to put a gauge on it and I just might still to find out the max forces from the cyls when it comes time to redesign it. You can almost stall the poor little gas engine before it goes over relief so I think its good for now. So many possibilities with this machine... I love it! I'm pondering over winter what route to go with it to make a versatile machine. A homemade hyd quick attach for the loader with a blade, bucket, pallet forks and a winch on the "rear" are on the short-list.

Glad you like the 5-ton limo! I'm pretty proud of it although its not finished yet. Its another one of those "possibilities are endless" type projects but I think that will be more of a play machine than a work machine so practicality might go out the window. I'll put up some updates when I can if there is interest on here.

Practical?  Whats more practical than bringing your logging crew to and from the worksite/bar/parole officer in a 6x6 limo?  Cmon. 


Make sure to put a hydraulic thumb on the forks.

I thought that 5 ton limo would be the perfect wedding rig....wyffie thinks I'm a little touched in the head. :snowball: :snowball:
