Recently purchased an new 4wd L2501 Gear Transmission with FEL and backhoe. I had read somewhere that to check the hydraulic fluid level the tractor should be shut off, FEL down on ground and Backhoe in transport position. At that point the fluid level should be 1/2 way up the view window. Mine did not show at all. Got a gallon of fluid from dealer and added it slowly with no visible fluid in view window. Added, the gallon and can just barely see fluid at the bottom of window. If I lower the backhoe bucket and extend it out completely the fluid is about 1/2 way up view window. Talked to dealer and my belief is they did not top the reservoir off after adding backhoe. he said the level I have now is correct. My question is should I be adding more fluid? or is this adequate. I do believe it was low when I received it(14 hours on unit). Any chance of any damage running it at low level. I guess it I should have checked it when delivered but we were kind of excited about our first new tractor and it was a matter of trust with the dealer. Thanks for your time. Great machine, we love it.
