US Market vs Grey Market Mitsubishis

[sschriber]

About 15 years ago I nearly purchased a Mitsubishi MT180D tractor from a local dealer. Flash forward 15 years - when looking at pre owned Mitsubishis, is there a way to tell the ones that were originally built for and sold in the US market vs. imported/rebuilt "grey market" tractors? Is there a difference in safety and functionality?

There is no difference in safety and functionality. On a US model pushing the throttle forward makes the engine run faster. On a Japanese model it runs slower.
