Wacker Neuson G150 mobile generator. You can clearly see the "WACKER NEUSON" branding and the "G150" model designation on the side. It's a substantial, enclosed generator mounted on a tandem-axle trailer, similar in style to the Airman generator we just discussed. These are powerful and portable units often used on construction sites, for events, or as backup power in various locations, including around Tomball. The "121 HW" likely refers to its power output and specific configuration. What are you interest
