Abstract
A transmission for a wheeled appliance responsive to pushing and pulling forces applied to a handle. The transmission includes speed reduction gearing and forward and reverse clutching elements which provide high power capacity, large speed reduction, durability, quiet operation and smooth power engagement. The main power train elements all rotate on parallel axes and the forward and reverse clutching elements are essentially independent of one another and resistant to wear.
