I just picked up a 642b. I was wondering if the service manual you can order through the Bobcat website is the same as the actual service guys get, or is it a watered down consumer version. It is in good shape, and I want to go through it to keep it that way! Unfortunately, it does not have auxiliary hydraulics, but with the info from the manual, I wanted to find out if it could be added, as it was an option on this model. Thanks in advance! I'm sure I will have more questions along the way! Ed
