Power and Precision in Tight Spaces

Engine Options for Any Application

Contractors can choose between two reliable Honda engine options with the PRO436: a fuel-efficient 5.5 hp class model for lighter applications or a high-output 9 hp class for more demanding work. Both engines deliver consistent torque, smooth operation, and the strength needed for professional finishing. With this versatility, the PRO436 adapts easily to residential interiors, commercial projects, or confined slab areas where precision matters most.
