National 6280HD Gladiator Walk-Behind Scraper

Manuals, parts diagrams, maintenance schedule and specs

The National 6280HD Gladiator is an electric, hydraulically driven walk-behind scraper with a 1.5 HP motor. National designed it for hard goods such as ceramic tile and hardwood, and says it handles soft goods too. It shares many features with the 6280 Commander but carries a heavier torque rating, a rounded front weight, siped wheels and built-in wheel scrapers.
