I use my Mustand MTL20, which is the same as a Gehl 70 or Tacheuchi 140, 81HP, to load up to 24' long oaks onto log trucks if the side stakes aren't too high. A wheel loader is the best for heighth, but the skid steer has it all over the wheel loader (CAT 910 in my case) for speed. I put 5' forks on my skid steer or CTL (Compact Track Loader) and it will walk all over in deep mud with a full load of hardwood logs.
I would not get any other brand or make other than the aforementioned. I know people that have tried this with bobcat, deere and case than they have had failures of either seals, cylinders or premature wear on the lift pivots. I have used mine for two years with zero issues.
I would not get a wheeled machine, with the heavy loads you will ruin the ground and will soon be loading in either deep mudd or deep dust and the wheeled machine will get stuck.
Thats my experience.
