    Grasshopper Z721D transmission fluid question

    You don’t need to pull all the lines. Drain the tank and pumps and replace filters. Moreover, you should refill with AW68 and run/drive it lightly to circulate. Drain again (flush) and repeat until fluid looks clear, then do a final fill. That should fix the weak performance on inclines.
