hello all, new guy here. I have an 873 f-series that I use with a Danuser post driver. The post driver manual says to put the lift arms in float once you have the post positioned where you want it. So my question is: can you put the arms in float with the arms lifted in the air. I tried putting it in float by pushing down against the post but no go. What am I doing wrong? All i do is lift the front end off the ground. Thank you.
