55kW

The JCB 55kW (74hp) EcoMAX engine meets current emissions legislation without the need for aftertreatment.  Adhering to the current EU Stage IIIB and US Tier 4 emissions legislation for engines between 37 and 56kW, these set emissions differ slightly to higher power ratings.

Our One-can solution

JCB engines over 56kW (74hp) meet stringent Tier 4 emissions legislation by using a compact, highly efficient SCR system for NOx reduction, while JCB engines less than 56kW (74hp)  require no after-treatment.
With the JCB compact 'One-Can' solution, the Tier 4 engine delivers an engine package that, unlike many competitors, can be installed in existing machinery without bulky alterations to body work.
