Abstract: An improved lawn combine includes a frame having a plurality of rotatable wheels, including a pair of spaced-apart rear wheels, supporting and coupled to the frame, drive-actuated feed devices mounted on the frame for feeding materials in prescribed dosages to the lawn surface and drive means mounted on the frame for propelling at least one of the wheels of the frame and for actuating the aerator and the feed devices. The combine further includes a pair of manually-operable brake assemblies, each of which is disposed for cooperation with one of the rear wheels. Each of the brake assemblies is movable between a non-engaged and engaged position relative to the associated rear wheel, in the latter position of which it at least frictionally retards rotation of the associated rear wheel.
