Nebraska Patent of the Month – March 2022

Lawn care is a lot more than just mowing and watering. Aerating is an incredibly effective method of increasing water, air, and nutrient flow to the grass. Aeration can be done using special devices that create holes by either digging or pulling out cores of ground. Unfortunately, these devices rarely get even penetration depth across sites or even within a single site. If the soil is too hard, the device may barely aerate the soil anyways.

Exmark Manufacturing Company, Inc. has been developing innovative solutions in landscaping and maintenance for over 30 years. Recently, they designed an aerator that uses an actuator to ensure even penetration across all soil types. The actuator sets and controls the tine depth and relays with a sensor to monitor the accuracy of this depth. A relief has been integrated to allow the tines to lift to a shallower depth if the soil hardness is deemed to be damaging. The automated system and actuator-backed support mean aerating a lawn no longer needs to be slow, challenging, or labor intensive.
