Bobcat hydrostatic drive motor fluid

This is a narrow, hands-on how-to: an owner draining and refilling the hydrostatic drive motor brake cavity fluid on his own T66, one side only. He shows the exact bolt sizes (9/16), measures drain volume against a 12-ounce bottle, gives the part number, notes the 500-hour/annual interval, and compares old vs new fluid color. Good for owners doing this specific service themselves; other maintenance is saved for separate videos.
