Loren, this reminds me, when I got my 630 tin all painted up and back on I had the ole girl at a local show with some of our other club members. We had to park our trucks and trailers 2-3 blocks away and drive the tractors back up to the display area. When I had the tractor in high range and 4th it seemed like the governor wasn't working and the engine would bog down and not fully come up to RPM and speed. Did OK in 3rd though. Didn't think about brakes but it didn't seem like it was a brake drag because it didn't pull to one side or the other. Could governor be messing up since it sat for quite awhile?
