In an aerator including a chassis mounted on wheels, a tine depth stop mechanism includes a base mounted on the chassis. A side wall is fixed to the base and has a plurality of apertures therein. A stop arm is movably mounted with respect to the side wall and has an abutment. The abutment has a periphery. A tine weldment is attached to the stop arm, and a tine wheel is rotatably mounted to the tine weldment. A pin passes through one of the apertures of the side wall and engages the periphery of the abutment of the stop arm. Upon a downward movement of the tine wheel, the stop arm moves with respect to the side wall until the pin abuts the periphery of the abutment, thus adjusting a maximum depth of the tine wheel below the chassis.

1. A tine depth stop mechanism for a self-propelled power aerator including a chassis having a forward end and a rearward end and a plurality of wheels engaging the ground comprising: a base mounted on the chassis;a side wall fixed to the base, the side wall having a longitudinal axis and a plurality of apertures therein, the plurality of apertures being distributed along the longitudinal axis of the side wall;a stop arm movably mounted with respect to the side wall, the stop arm having an abutment, and the abutment having a periphery;a tine weldment pivotally attached to the stop arm;a tine wheel rotatably mounted to the tine weldment;a pin adapted to be placed within a selected one of the apertures of the side wall and engaging the periphery of the abutment of the stop arm,wherein upon a downward movement of the tine wheel relative to the chassis, the stop arm moves with respect to the side wall until the pin abuts the periphery of the abutment of the stop arm, so that a maximum depth of the tine wheel below the chassis is adjusted by the pin passing through the selected one of the plurality of apertures. 2. The tine depth stop mechanism of claim 1, wherein the base has a vertical position relative to the chassis, and the vertical position is hydraulically adjustable. 3. A tine depth stop mechanism for a self-propelled power aerator including a chassis having a forward end and a rearward end and a plurality of wheels engaging the ground comprising: a base mounted on the chassis;a side wall fixed to the base, the side wall having a plurality of apertures therein;a stop arm movably mounted with respect to the side wall, the stop arm having an abutment, and the abutment having a periphery;a tine weldment attached to the stop arm;a tine wheel rotatably mounted to the tine weldment;a pin passing through one of the apertures of the side wall and engaging the periphery of the abutment of the stop arm,wherein the side wall is a sleeve having a longitudinal axis, a forward sleeve end, and a rearward sleeve end,wherein the stop arm has a forward end portion and a rearward end portion, and the abutment comprises a longitudinal slot extending rearwardly from the forward end portion, the longitudinal slot having a forwardmost end portion, the stop arm being telescopically mounted within the sleeve with the forward end portion of the stop arm oriented toward the forward end of the chassis,wherein the tine weldment is rotatably attached to the rearward end portion of the stop arm,wherein the pin passes through one of the apertures of the sleeve and engages the longitudinal slot of the stop arm, andwherein upon a downward movement of the tine wheel relative to the chassis, the stop arm moves translationally with respect to the sleeve until the pin abuts the forwardmost end portion of the longitudinal slot, so that a maximum depth of the tine wheel below the chassis is adjusted by the pin passing through one of the plurality of apertures. 4. The tine depth stop mechanism of claim 3, wherein the forward end portion of the stop arm protrudes from the forward sleeve end. 5. The tine depth stop mechanism of claim 3, wherein the apertures are essentially perpendicular to the longitudinal axis of the sleeve. 6. The tine depth stop mechanism of claim 4, wherein the apertures are essentially perpendicular to the longitudinal axis of the sleeve. 7. The tine depth stop mechanism of claim 3, wherein the base has a vertical position relative to the chassis, and the vertical position is hydraulically adjustable. 8. The tine depth stop mechanism of claim 4, wherein the base has a vertical position relative to the chassis, and the vertical position is hydraulically adjustable.
