Good post Hobo.
The parking brake extender is the best deal ever if you're old or fat or both.
Reaching down to your shoe to set the brake was not one of Ford's better Ideas. They changed that in 76 on the 3600s.
And yes, there have been a lot of that era tractor went up in smoke because of a pinched battery cable. I bought the tractor in the photo because of a fire.
I miss the foot throttle on mine.
Had an original Ford one for about 10 years but gave it up for some fancy British made 3000 fenders and step plates to match.
Had run N fenders up until then.
