I just bought a L2002.It is going to need piston rings because it is very hard to start and blowing oil out the exhaust and blowby tube.I understand my little Gray L2002 is a lot like a L275.Tractordata shows the L275 has a live PTO and my L2002 does not.Is this correct?What type of fluid goes in the rear L&R gear housings at the axles?
