Crazy Engine Awakening for a GMC Detroit 4-71 after 30 years

1950 GMC Detroit 4-71 Roars after 30 years!

During 1950 two new heavy duty diesel tractor models were released by GMC with medium duty cabs and DD 4-71 engines. They became the best selling tractors in their class because they weighed and they costed less than the competition.

The following is a 1950 GMC 4-71 Detroit Tractor that had been sitting since 1981. These guys changed the oil, the diesel and freed up all the injectors but probably didn’t make some safety precaution in insuring the emergency stop would trip from the inside of the cab…

And watch what happens when the engine finally starts! This was for sure a noisy moment…
