New & Used Kubota Lowboy II GL11000TM 11kW Generator
Kubota’s Lowboy II GL11000TM is a compact, enclosed industrial diesel generator delivering up to 11 kW standby and 10 kW prime power at 120/240 V single‑phase, 60 Hz. Powered by the reliable Kubota D722 three‑cylinder, water‑cooled diesel engine, it provides efficient, low‑vibration performance for demanding applications such as construction sites, rental fleets, farms, telecom, and light commercial backup.
The Lowboy II design lowers overall height and weight, making transport, placement, and installation easier while retaining a fully enclosed, sound‑attenuated package. With a built‑in diesel tank of about 7.4 gallons, the GL11000TM offers extended run times up to roughly 7–12.7 hours depending on load, reducing refueling frequency on remote or overnight jobs. Electric start, integrated safety shutdowns, and output terminal lugs make connection straightforward for electricians and professionals who need a robust, long‑life power source.
