140H Caterpillar Motor GraderThe Caterpillar 140H motor grader was first produced in 1995.

It features a 3306 turbocharged engine that produces up to 185 flywheel horsepower (fwhp), and direct drive powershift transmission with electronic control. Other specifications may differ slightly based on where a 140H motor grader was built and in what year.

Caterpillar 140H motor graders built in the United States have the serial prefix 2ZK, 8JM or 8KM. Australian models use the 9ZN prefix, and Brazilian models use the prefix 3AS, 5HM or 9TN.

The 8JM, 8KM, 5HM and 3AS units have engine power management, while other models have variable horsepower.
