Well, I just changed the fluid in my 1711 Hydro due to a leaking gasket on the rear end. I didn't realize changing the filter would be such an ordeal. The mule drive assembly is in the way of getting the filter in position easily. Anyway, what I'm wondering about is if there is another way of putting the fluid back in other than through the dipstick tube. It took forever. As I put the fluid in, air belched back out through the tube. I have looked all over for another orifice to add fluid, but found nothing. That's why I'm turning to the experts. Any help is appreciated.
