    Hydraulic oil / diesel fuel mix "oops"

    Thanks for the input. Sadly, the machine has been run for about 2 hours before I was made aware of the problem. I had it in mind that I will need to flush the system, but there was always the hope that someone would say awww, don't worry about it. I guess you're right ISZ, a few gallons of oil...

    John Deere 644E transmission troubles

When the machine is shifted from either forward to reverse or vice versa, it takes up to 3 seconds for the transmission to engage. Also, when it is traveling, and is shifted from 1st to 2nd, it takes up to 7...

    Ok, I see that others have had problems, so I think I will give it a try. This is my first reply, and I hope it works a couple more times so I can post a new question. Thanks for the service!
