What would be the right way to check the hyd oil in the site glass on the 2720? I know it should be approx half way up the site glass but would you check it with all the attachments on and extended as I have a 46 hoe and front end loader or does it matter at all? The manual just says approx half way up site glass. When you have the hyd. cyl.'s with the piston rods out they take more fluid than with the piston rods in. I am not sure if it would matter if one would have almost all the piston rods out at one time or would it effect anything at all. Or is this a question best left to the dealer? Thanks for the info Bob
