From your first post describing your use on "hills & slopes" The NH will be much more stable. Longer wheelbase and track & bigger tires/wheels. The noise might just be "hyd. noise" I had a brand new JD 260 and it was loud. The control linkage on the drive motor might be out of adjustment. Be aware that in the woods you will need over the tire metal tracks on either machine. No help on the BC oil issue, sorry.
