Grasshopper 725k

On a 725k what weight oil goes in the transmission reservoir? The grasshopper number doesn't do me any good.Was looking to see if its 10wt hyd. oil or 30 wt. ? Also does anyone know what the Napa numberv would be for the trans. filter.(grasshopper number 100850) Don't have a Grasshopper dealer in my area, so use Napa for most of my parts.Thanks to anyone that can help me.

I moved your thread to the Grasshopper Forum. You'll get a better response there. :thumbsup:

My local dealer told me that they use Castrol W30 synthetic as a less expensive replacement to the grasshopper trans oil.
