I noticed the machine (mill) wasn't level in some of those pictures. Its extremely important to keep a mill as level as possible while cutting for a number or reasons. Keeping the down pressure on the rear mouldboard correct is one reason, Mouldboard pressure and grade control sensors are affected when the mill isn't level. The cut may have extra milling(s) material left in it because the Mouldboard isn't scraping correctly. The sensors may not hold the exact depth desired.
this is the final phase the hatfieldd meats expantion.
