John Deere 425
I'm having an issue with my John Deere 425 and oil consumption. It consumes around 1/2 quart of oil for the 2 acres I mow. Quite a bit if you ask me. I think the issue may be either the valve cover gasket or perhaps a cracked valve cover. One additional issue, when I replaced the mower blades (48" deck) with "gator blades" (seem much heavier than the standard high-lift deere blades) the mower starts fine but once the deck engages taxes the engine to such an extent it shuts down. Any ideas on either of these issues?????
