When you get your Bagger lined up where you want it bring your Forage Box over and line it up with the Baggers Auger bring your Ag Bags over with a Forklift or I use a TeleHandler pull the Bags up behind the Bagger jump in the Tractor that you have hooked up to the Bagger and it should tell you to hook up the Ag Bags. Once you do all of that jump in the Tractor that you have hooked up to your Forage Box and start unloading your Forage and then jump back into your Tractor that you have hooked up to your Bagger and it should tell you to start Dumping your Forage (Grass or Chaff). It turns your Grass or Chaff into Silage instantly no waiting for the Fermentation Process. I am currently at (26%) full with (2) Forage King Boxes of Grass dumped into the Bagger on the Alma, Missouri Map. Excellent Map by the way. My guess is that once you get the Bag to (100%) full you detach the Bagger and then you can start pulling from the Bag to fill up your TMR Mixer. I hope this helps.
