Create a flawless striped lawn with the Cobra RM51SP80VX. This 20" (51cm) self-propelled rear roller mower is powered by Cobra’s twin 40V MAX+ battery system, delivering strong, quiet, and low-maintenance performance. The full-width rear roller produces a traditional striped finish, while 6 cutting heights from 17mm to 75mm let you tailor the cut to your lawn. A tough steel deck adds durability, and the large 70L grass bag reduces the need for frequent emptying. With its wide cutting path and powered drive, the RM51SP80VX is ideal for larger lawns and cordless convenience. (Not compatible with standard Cobra 40v batteries).
