Caterpillar D6

It didn't actually fit in the shop, but I did work on it.  It has some kind of problem with the steering.  Older dozers had simple mechanical clutches and brakes that were operated by big levers that you pulled on. They could be fixed with a crescent wrench and a hammer.  This machine has a new joystick type control.  I think there are a lot of complicated hydraulics involved.  I may to have to track down a service manual to figure it out.
