Abstract: An assembly is provided for towing first and second push-type lawn mowers behind a riding mower. A base plate attachable to the rear of the riding mower releasably holds a tow bar. First and second tow arms are releasably coupled to the tow bar and are each adapted for pivoting motion relative to and in an arc defined by the tow bar. The first and second tow arms are received in respective first and second couplers that are attachable to the first and second push-type mowers, respectively. The first and second couplers allow releasable attachment of the respective first and second tow arms. Each coupler is configured to allow rotational movement thereof relative to the tow arm such that respective first and second mowers to which the first and second couplers are attached can follow the contours of the terrain, thereby providing an even cut. The towing assembly is easily disassembled and re-connectable. Likewise, each push-type mower is easily removed from the towing assembly for quick use.

Abstract: A wheelchair brake system is provided that allows an operator of the brake system to retard and/or stop the motion of the wheelchair. The brake system provides for independent and variable application of a braking force to wheels of the wheelchair. The brake system includes first and second brake force application assemblies, first and second braking assemblies, and actuation lines coupling the respective brake force application assembly to the braking assembly. The brake force application assemblies may be associated with handles of the wheelchair that allow a secondary or ancillary operator to apply a braking force, but may be associated with armrests of the wheelchair for use by an occupant. The brake force application assemblies are rotationally positionable and/or pivotally positionable to achieve various orientations thereof. This provides ergonomic placement of the handles for comfort and ease of brake force application.
