Abstract: A walk-behind soil aerator includes an engine, a differential, and left and right tine assemblies driven by the first and second output shafts of the differential, and a variable speed drive means between the engine and the differential, as well as a control means accessible by an operator walking behind the aerator which allows the operator to make tight turns by gradually reducing the speed of the drive means to a desired slow speed in order for the driven tines to drive the aerator through the turn and then gradually increasing the speed of the drive means without having to change the engine speed.
