The skid steers and CTLs are powered by Yanmar 3.3 or 3.1 liter diesel engines. The large-frame model engines provide up to 10 percent more horsepower than the previous D-Series models. Engines with more than 75 horsepower will meet Interim Tier 4 emissions requirements, while engines less than 75 horsepower will be Final Tier 4 compliant. The engines in all E-Series models feature cooled exhaust gas recirculation (EGR) with an exhaust filter consisting of a diesel oxidation catalyst (DOC) and diesel particulate filter (DCF).

The E-Series consists of nine total models. In skid steers, there are three large-frame models (326E, 328E, 332E) and two mid-frame models (318E, 320E). In CTLs, there are two large-frame models (329E, 333E) and two mid-frame models (319E, 323E). All models will be compatible with more than 100 available Worksite Pro attachments.
