Wonder-Boy with 24" Rotary Mower

Here is modern mechanical help at its functional, powerful best.  You bring the rugged  4HP engine to life . . . gently set it in motion with the exclusive Joy Stick control . . . one hand starts, stops and steers.  Wonder-Boy's "soft action" clutching starts you smoothly . . .  and Two-Speed Axle provides speed a-plenty as you ride.  Patented "Full Flex" Hitching provides guided full-flotation of the mower on hills, down ditches, up slopes . . . never scalping!  And there's no power lost when you shift the cutting gear - - a governor cuts in automatically to compensate for your cutting load.  Your lawn is trimmed in no time - - and you've never left your comfortable "chair!"

DUOMATIC axle is a planetary transmission that can be shifted easily and permits dropping down to lower speed when more power is needed. Power divided equally to both drive wheels by a 4 pinion gear differential. 100% free wheeling, easy to maneuver.
