Hi Vic,
I too am new. I have a 2005 L2800 and noticed hydraulic fluid on the ground and coming from the bottom of the clutch area and followed up the wetness and found the Hydro pump inlet hose, coming from the filter area to the pump on the engine, was cracked and seeping fluid. After looking at some info on another forum site(tractorbynet), I heard it was widespread and maybe covered under warranty and/or replaced free of charge. Since it is in a negative pressure realm, there was not a large volume of fluid leaking out. I read that the big problem is that it sucks air and whatever else into the system and can ruin it. I am trying to find some more posts on this subject here but so far not much said. Have you heard of this?
