[etlioglu]

Hi,
Nowadays I am researching the technical innovations in backhoe loaders. I found some of innovations. These are
*intelligent hydraulic system
*articulated backhoes
*4 wheel steering and crab steering
*Power shift mechanism
*a control system which restricts the movement field of backhoe part of vehicle because of the obstacles.

Do you know the other technical innovations in backhoe loaders?
Thank you...
