You were never baling in a field with a guy on one side of the tractor (the seller) telling you to slacken the bales and another guy at the other side of the tractor (the buyer) telling you to tighten them. It would do your head in. There are lots of weighbridges in the country, weigh an odd load and get an average weight per bale and work away. It riles me no end to see people talking about making decent bales when they know full well they have the density set to the bare minimum. And those who shout the loudest about it are usually the worst offenders.
