Thanks blue steel. I misunderstood dealer about computer. They had to reprogram the computer so it will recognize the new solenoid in the injection pump. They had to get a new computer from LS to be able to program the tractors computer. I got tractor back today but didn't have time to do anything but park it in the shop. If tomorrow is not as hot as today (102)I plan to hook up the flail mower and test her out. Hopefully no more problems. Dealer has been great trying to take care of everything.
