So....my L3902 is coming up on 400 hours, was getting ready to service it, decided to check front axle fluid level after thumbing through the manual, was VERY LOW. I quit counting pumps around 50 strokes from my five gallon buck pump. I'm not sure how low it was, but was clearly not filled up from factory or checked at dealer when we bought tractor, really not sure if it had anything in it at all. what now? I guess the front axles are pretty tough, pretty P.O.'D that the front axle has been running low on oil all this time....not sure how I should approach this....bet is going to be expensive when it fails down the road.
