Gibson Model D Remote Run/Stop and Throttle Controls

I'm guessing the person who installed the Petter AC1Z diesel engine on this Gibson tractor just hadn't gotten around to installing engine controls where the operator could reach them from the driver's seat, as both the throttle and stop lever were only on the engine. This photo below shows the Run/Stop lever, and under it is the throttle control, in which the threaded knob is turned out to slow the engine down and turned in to speed up the engine. You can kind of see a string on the stop lever, which was a less-than-ideal method of shutting the engine down from the driver's seat.

1948 Gibson Model D - Clutch Remedy

Hmm, a couple days ago I had a Gibson tractor in the garage. Now I have two. Was my Super D2 pregnant when I bought it? Apparently, because now I have two Gibson tractors in the garage, the Super D2 and now a D.

The D is older than the SuD2 by a couple years. It was also quite a bit more of a bare-bones offering by the Gibson company. Whereas my SuD2 has a proper steering wheel, hood, fenders, dash, and hydraulics, the D is absent all those "luxury" features. So, how do you steer, you ask, if there is no steering wheel? Tiller, of course. While it isn't very visible in this photo, it is there near the engine air cleaner. Pull the tiller to the rear to go right, push forward to go left.

Gibson Super D2 Tractor T96 Shifter Repair

When I bought this tractor, I knew either the shifter or transmission needed help, as it was sometimes almost impossible to shift between gears, and on a couple of occasions got stuck in two gears at once. I've had the shift tower off the transmission several times, greasing and oiling to no avail, and finally the last time I had it off (always the last time, right), I realized what was going on. The shift lever was twisting sideways and causing the square bottom end of the shift lever to bind between the two shift forks when in gear (red arrow below).

Gibson Super D2 Tractor Hydraulic Valve Repairs

I recently purchased this 1950 Gibson Super D2 tractor and have been slowly fixing the issues it came with. I've wanted another Gibson for some time as I'd owned one a number of years ago that I bought from my brother. Here is the Super D2 in all its glory a couple days after I got it home:
