Abstract

A self-contained steering, clutch, and brake assembly is provided having a housing for connection to a rotating drive shaft having a drive hub mounted on an extension thereof, a brake hub mounted to the housing, and a clutch drum movable to engage either the drive hub or the brake hub. These engagements are made through coaxial, multi-disk clamping assemblies which serve to increase engagement surface area within the minimal confines of the housing. The clutch drum is constantly connected to a standard size wheel axle through a compound reduction chain drive which is also enclosed by the housing. The clutch drum is normally biased into engagement with the drive hub and a rotary cam actuator is provided to move the clutch hub against the biasing spring and into engagement with the brake hub. The housing is adapted to be bolted directly to the mower deck without special deck reconfiguration.
