</font><font color="blue" class="small">( Hope you don't mind a newbie jumping in here. I saw this thread and like with many this is a subject of interest.
I'm also put off buy Cub's price on this fliud and would like to have a choice. Time for the first filter change last month and I had to pay $13 for a qt of this stuff. There can't be that much magic in this stuff to warrant that kind of price.
I see where Lazy said only need to change fliud every 400 hrs. Well, not according to my manual. After initial change, filter every 50 hrs and fluid every hundred.
Tractors 2 yrs old now so when it's time for another change, I'll be looking into an alternate as I'm not about the pay $13/qt to do a complete change. )</font
