The Black Ops Edition Warrior Equipment Tomahawk WE-2047P puts a 14 HP propane engine behind the same 4 head planetary grinder as the electric Tomahawk. With no cord, generator or panel hookup to plan around, your crew can grind, polish and remove coatings on job sites that have no electrical service. The gear-driven drivetrain carries 383 lbs of head pressure across a 20.47 in path at 829 RPM, prepping 800 to 1,100 square feet per hour.
