PowerTech M and E 2.4 L engines from John Deere have gone from Tier 2 directly to Interim Tier 4 and European Union Stage IIIA compliance. The M engines are rated from 36 to 37 kW (48 to 49 hp) and are suited for low-power applications. Mechanical controls provide flexibility, and aspiration is turbocharged. The PowerTech E is rated from 45 to 51 kW (60 to 68 hp) and offers an electronically controlled unit pump fuel system with improved cold-start performance, engine speed control, and torque curve shaping. Both engine series feature two-valve cylinder heads, fixed-geometry turbochargers, self-adjusting poly-vee fan drives, and 500-h oil changes.
