backhoes
 
There have only ever been a few Technic backhoes and the oldest two are functional marvels, among the most complex of any Technic models.  The newer two are smaller and only slightly less full featured.  The list of features is basically the same, but the means of accomplishing those functions is quite different.  One does almost everything with pneumatics and uses 10 pneumatic cylinders, another uses only 3 pneumatic cylinders and does everything else with gear systems, and yet another uses mini mechanical linear actuators.  All feature raising and dumping buckets, functional excavators including slewing, outriggers, and steering.

One obvious point of similarity is that every single backhoe has been yellow.  This is a common color in many Technic heavy equipment models, although there are some exceptions in excavators.

It is impossible to pick a favorite here.  For sheer pneumatic glory, 8455 has no rival among any Technic set.  But 8862 is even bigger and the gear systems are wonderful.
