The cylindrical roller portion is provided as a handrest. The first end of the cylindrical roller portion is oriented opposite to the second end of the cylindrical roller portion.

Tine assemblies (100a, 100b, 104) are secured by a single bolt (126) extending diametrically through each tine (120) located in a cavity (112) of a tine plate (110). An outer tine assembly (104) is connected to a sleeve (116) rotatably mounted on independently rotatable shafts (102) to which inner tine assemblies (100a, 100b) are connected. A tine cover (50) removably closes an opening (40) in the top plate (28) and in which weights (70) are removably received over the tine assemblies (100a, 100b, 104). Transport wheels (134) are moveable by pivoting a stop plate (140) to position an upper pivot axis (150a) of an abutment bar (150) ahead of or behind the stop axis (142) and lower pivot axis (150b). A stop (146) positioned on the stop plate (140) without the use of tools adjusts the depth of the tine assemblies (100a, 100b, 104).

An agricultural tillage implement has a vertical tillage section and an aerating section behind the vertical tillage section, each extending substantially perpendicular to the pull direction of the implement. Individual vertical tillage elements, such as disc blades, can be indexed with individual rotary tine assemblies of the aerator section so that discrete holes formed by the aerator section are positioned between substantially continuous slits formed by the vertical tillage section. A ground deposit system deposits a component on the ground and may be configured for conducting and depositing a granular component, such as seeds, fertilizers, minerals or the like, or liquid components, such as liquid manure.

An aerator with variable delay of the coring head includes a lift/lower control on an aerator control panel that raises and lowers a coring head and starts or discontinues rotation of a coring head crankshaft that reciprocates a plurality of coring tines. A delay timer provides a variable time period between starting to raise or lower the coring head and the rotation of the crankshaft. A switch is provided on the control panel to preset the time period.

A gardening apparatus including a housing having an inner chamber, a handle, a hose coupled to the handle and configured to actuate release of a granular substance, a receiving clip, a plurality of wheels, a rotatable structure, and a plurality of circular devices including a plurality of projections, wherein the plurality of circular devices is removably attached to the plurality of wheels. The gardening apparatus is useful for simultaneously fertilizing and aerating a lawn or garden, while promoting speedy germination of plants, flowers, vegetables, and more.

A tension control mechanism includes a drive wheel and a jack wheel rotatably mounted with respect to a chassis of a self-propelled power tool. An idler arm is pivotally mounted to the chassis and carries an idler wheel. A flexible drive member entrains the drive wheel and the jack wheel and drives the idler wheel. First and second bias members bias the idler arm in opposing rotational directions, which move the idler wheel toward or away from the flexible drive member to respectively increase or decrease tension. A ratchet arm is attached to the idler arm has a hook. A ratchet head is fixed to the chassis and has ratchet teeth for engaging the hook to permit relative motion between the hook and the ratchet teeth to increase tension, and to limit relative motion between the hook and the ratchet teeth to prevent an excessive decrease in tension.
