The lithium-ion technology powering the new Workman GTX Lithium is built to deliver hours of reliable performance. It’s the largest lithium-ion model in its class, so it can handle big jobs. At nearly 400 pounds (181.4 kg) lighter than traditional Workman GTX models, it makes a big impression on productivity without leaving a big impression on turf. The lithium-ion power packs are maintenance-free and have a long lifespan, so the machine is always ready to get to work.
