I have an L245DT with a 1200 FEL mounted. I just picked this unit up and would like to change the fluid and filter before I start using it. There is a reservoir tank by my right knee while sitting on the tractor but I don't see a drain plug. I am thinking that if I disconnect the lowest hose I would get most of the oil out of the tank. How would I drain all the hydraulic hoses and the cylinders. Maybe I am over thinking this whole thing !!
