Computers have Taken Over!!!!

I was at Ag Power Enterprises picking up a part and I took this picture of one of the technicians. With todays equipment, technicians have to be good with a wrench and computer. Many times the first thing a technician does is plug in his lap top computer into the computer system on the tractor. In fact, with the newest tractors, the service manager at the dealership might know you have a problem with your tractor before you do. The computer system on the tractor is in contact with the technician at the dealership. If the computer throws a code it contacts the technician. He then knows what is wrong, how to fix it and what parts he might need! Do we need someone in the cab anymore?????
