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.

A lawn combine, comprising: a frame including a plurality of rotatable wheels supporting and coupled to said frame; a drive-actuated rotatable aerator movably mounted on said frame for movement between a lower operative position, in which it is disposed for engagement with a lawn surface and an upper raised, inoperative position, in which it is disposed for non-engagement with the lawn surface; means for moving said aerator between said operative and inoperative positions thereof, mounted on said frame; drive-actuated feed means mounted on said frame for feeding materials in prescribed dosages to the lawn surface in an area generally beneath said frame, said feed means comprising a main hopper mounted on said frame having a lower opening through which material fed to said hopper is dispensed and a plurality of bins mounted on said frame, each of which has a lower slot-shaped dispensing aperture for feeding a particular material to said main hopper, said bins each including drive-actuated regulator means for metering material fed thereto in prescribed dosages to said main hopper, said regulator means each including a rotatable, cylindrical sleeve having a plurality of longitudinally-extending slots formed therethrough spaced about the periphery thereof, which sleeve is rotatably supported on said frame such that at least a portion thereof is disposed beneath one of said slot-shaped dispensing apertures parallel to the longitudinal axis thereof, said slots being movable in a rotary fashion between a loading position, in which the slots oppose said slot-shaped aperture, and a discharge position, in which material fed into said slots is discharged into said hopper, said regulator means also each including a plurality of interconnected rods, each of which is slidably mounted in one of said slots of said sleeve, said rods having a first portion having an upper surface which lies substantially flush with the outer circumferential surface of said sleeve and a second portion having an upper surface which lies substantially flush with the inner circumferential surface of said sleeve, said rods being movable between a first end position, in which said first portion thereof is disposed beneath said slot-shaped aperture, and a second end position, in which said second portion thereof is disposed beneath said slot-shaped aperture to thereby respectively permit and stop feeding of material to said hopper, said regulator means each also including control means for controlling the position of said rods; drive means mounted on said frame for propelling at least one of the wheels of said frame and for actuating said aerator and said feed means; and a pair of manually-operable, frictional brake assemblies, each of which is disposed for cooperation with a different one of said rear wheels, each of said brake assemblies being 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.
