Tool Drive System
A tool drive system for transferring rotational power from a rotational tool, such as a drill or ratchet, to at least one input drive shaft which then transfers the power to at least one output drive shaft. The angle of at least one input drive shaft being adjustable relative to at least one output shaft. The tool drive system comprises a round housing with an angle adjuster attached to the input shaft that assists in adjusting and locking the angle of the input shaft relative to the output shaft in an almost circular span. The input and output shafts may be positioned in a user-selected gear ratio from the input to output shafts or vice versa.

Turf Aerator Core-Cleaning Systems
An aerator plug-core cleaning system for ground surface collection of turf cores extracted from a turf core-aerating apparatus. The core-cleaning system comprises a core-cleaner that primarily attaches to either a walk-behind or tractor pulled aerator machine. The core-cleaner entraps and pushes the extracted cores along behind the core-aeration machine until being lifted in about a vertical manner by secondary attachment to a rear raise-able portion of the core-aeration machine at which point the cores are left in a pile for disposal.
