mornin, i have a t2420 with a front loader. am haveing a little problem but not sure if it's normal.when i'm digging into a dirt pile or even a SNOW pile, the hydralics will not lift the loader as i am going into a pile unless i stop or sometimes even back up a bit. the hydralic oil is up to where it is suposed to be and i changed the filter also. is this normal or is there something wrong. it has done this from the day i bought it new. any ideas would be great. thanks
