Mules are slightly smaller than their horse parent, and when they grow they share traits of both a donkey (the long ears), and the horse (color, tail, etc.). A Mule in the grass.
For example, a 2014 Ford F-150 is considered a half ton truck but most variants can carry a lot more than 1,000 pounds in the bed. Since these terms are probably not going away any time soon, it's best just to think of them as smaller, mediumest, and more than medium.. (Pause for laughter).
A Squeeze: A truck that picks up 56 to 68 bales at a time and loads and off loads semi trucks. A squeeze is driven as an independent truck and is legal on all highways. A squeeze has two large hydraulic arms that are 10' long that squeeze a dump of hay to be loaded and off loaded. It takes a squeeze driver 30 minutes to load a semi truck with hay. A ton: 2000# pounds of hay to the ton. A retail three string bale weighs 100 # there are 20 bales in a ton. A feed store ton can be 16 bales. A semi holds 24 tons on a truck.
