Practical, Quality Design...

Cutaway view (at right) shows the completely functional design of the Gravely . . . the motor, chassis and attachment flowing cleanly and simply into one complete, compact, precision machine.

Each part is designed and machined to be used with the others — they're not merely assembled. The Gravely uses the same type of drive and transmission as an automobile, to give DEPENDABLE power.

Powerful, Compact and Rugged!

The Gravely engine is conservatively rated at 6.6 hp. It's large bore and stroke at a comparatively low piston speed mean dependable power for the toughest jobs . . . real lugging power.

Gravely's built for work... the really tough jobs. Everything is compact, functional, precision machined; every part is a heavy-duty part, built to withstand day-in and day-out use and abuse.
