JD 548D

So I’m pretty sure the main hydraulic pump went out in the skidder.( early 90’s 548D grapple). I was trying to get it closer to a road to work on. It’s several hundred yards from a road or my closest landing that I can get a vehicle to.  Nothing is working.  No tranny, no grapple function, no blade. So I tried towing it.  Didn’t work.  The rear left tire will not spin.  Or it tries to spin backwards? I’m in neutral, e brake is in the off position, and I removed the driveline between the tranny and the rear.  Any suggestions? Thanks

If your machine has a diff lock, could it still be engaged?  Had similar trouble once with a 640 that broke the lower hinge and had to be chained up to move.  Fought me tooth and nail getting lined up on a drop deck.  Once repaired the mechanic said he found it with the diff lock engaged.  Kind of a “duh” moment for me.  Never gave it a thought.  Just a suggestion!
