Abstract

The exit end of the discharge chute of a riding lawn mower having rotating grass-cutting blades is provided with a rotatable deflector plate, the position of which is controlled through a linkage by the operator of the lawn mower while seated and without stopping the lawn mower. The operator, through the linkage, can shift the deflector plate between an operative position closing the exit end of the discharge chute, an inoperative position opening the said exit end, and positions therebetween. The deflector plate is provided with apertures of size and spacing sufficient to prevent the passage therethrough of stones large enough to cause physical injury to persons or damage to property in the vicinity of the exit end, while permitting the passage therethrough of grass cuttings, small stones having no potential to cause such physical injury or property damage, and air forced through the discharge chute by action of the grass-cutting blades.
