At 14,000 RPM you are more like running a jet engine or is that a typo?

It means Mack still exists in 2105 and Vulvo failed to kill the bulldog It might have a jet engine and a beer tap!

0 B MACK Posted February 20, 2019 Share Posted February 20, 2019 I'm not sure if this is the same thing you are talking of. The company I work for has two RD MACKS dump trucks and they had a governor set up on the PTO. The engine speed was not affected dumping in a pile or while driving spreading the load. But the PTO would cut out if the RPM"s went above 1250. It was a real pain in the ass dumping loads with them.
