Meet our new Tier 4 Common Rail Direct Injection Engine. It's what powers our new NX & RX Tier 4 KIOTI tractors. Featuring Daedong® Eco Technology and available in 45 hp to 73 hp, they are engineering works of art. It's the future. Available now.


Toughness Test

How Tough Are Our New Tier 4
Compliant Engines?

Performance tests were done in the Italian Alps at 12 degrees F. Then subjected to prolonged exposure to extreme heat. Performance maintained and all systems passed with flying orange colors.


Some Technical Stuff For You Gear Heads

What is Tier 4

Tier 4 is an emissions standard put in place by the EPA and Clean Air Act. KIOTI is one of the first tractor manufacturers to offer Tier 4 compliant tractors in North America.


How Did We Do It?

To comply with the Tier 4 emissions standards, KIOTI tractors use Exhaust Gas Recirculation (EGR) developed by Daedong which re-circulates the exhaust gasses to burn again.

Exhaust gasses are cooled before being re-circulated. That keeps the combustion temperature lower, reducing emission levels.

Then the Diesel Oxidation Catalyst and Diesel Particulate Filter take care of the particulate matter.

Did You Know?

KIOTI Tier 4 engines are made by Daedong, the same people who make KIOTI tractors. That means the majority of major components are designed and built in the same place. By the same people. Not many manufacturers can say that.
