I have a new holland l445 with a Wisconsin engine. Just got it at an auction. This is the only skid steet I have that does not have down force. When I press the pedal for the tilt it will lift it, but the arms raise like there is no resistance. Furthermore, if I drop the bucket tilt down and then drop the lift arm pedal down it doesnt lift the machine. The arms just stop. I was wondering if this is normal for this machine or if there is a valve or something.
