The present application discloses a rolling lawn aerator, including a perforating device, where the perforating device is capable of rolling on a lawn so as to perforate and aerate the lawn. The perforating device includes a body assembly and a plurality of perforating assemblies, and the plurality of perforating assemblies are arranged in a circumferential direction of the body assembly; and each of the perforating assemblies includes a perforating pipe, and at least a part of a structure of the perforating pipe exceeds the body assembly in a radial direction of the body assembly.

A novel hollow tine aerator has been developed that features a bevel tip and bevel ejection system for enhanced soil penetration and seamless soil core removal. This innovative design addresses the limitations of conventional aerators, enabling efficient soil aeration and improved turfgrass health. The bevel tip design, with its inclined cutting edge, minimizes resistance and facilitates smoother penetration of hard or compacted soil. The bevel ejection system, comprising an angled base on top of the tine, guides the soil core upwards and exits through the open groove, eliminating the need for manual intervention. The integration of the bevel tip and bevel ejection system offers several benefits over conventional aerator designs. Enhanced soil penetration enables deeper aeration, promoting root growth and nutrient uptake. Seamless soil core removal eliminates the need for manual dislodgement, saving time and labor. Reduced operator fatigue enhances comfort and efficiency during aeration tasks.

An aerator includes a punching assembly including a fixed plate and multiple rows of punching nails installed on the fixed plate and extending from the bottom surface of the fixed plate, with each row including multiple punching nails; and an installation body, on which the punching assembly is installed, wherein the installation body is provided with a hand-held part, the hand-held part is configured for the user to hold while using the punching assembly to punch holes. The aerator provided herein is not only high in punching efficiency, flexible and convenient to use, but also simple in structure and low in cost.
