I have a GD Chariot Jr. with 23 kawasaki. The dealer changed the oil the first time at 6 hours. I now have almost 50 hours and need to change the oil. As you know, Great Dane has terrible manuals. Is there as easy way to drain the oil without getting it all over the place ? I see the drain plug right below the filter, but it just opens up to the flat frame. If I drained it here, it would cover the frame and run all over the place. Can I rig a drain tube so I can drain it out the back ? Any help would be appreciated.
