The TMG-GLA19 Walk Behind Lawn Aerator is a self-propelled walk-behind machine designed to relieve compacted turf by removing small plugs of soil. Opening the surface allows air, water and nutrients to move more easily into the root zone, making it a practical choice for seasonal lawn care and ongoing grounds maintenance.

Its 24-tine coring drum creates a consistent pattern across the working path, while removable counterweights let the operator adjust downward pressure for changing ground conditions. The self-propelled drive moves the machine through the work area, reducing the effort required to maintain a steady pace over compacted lawns.

A 7 HP Kohler CH270 engine powers both the coring and travel systems. Separate controls for movement, tine engagement and parking keep operation straightforward from the handle position. Built for landscapers, property-maintenance crews and homeowners, the TMG-GLA19 provides an efficient way to prepare compacted lawns for healthier-looking growth.
