Powered rakes are often referred to as a dethatcher, which is simply a device that digs into the ground shallowly and removes dead grass, thatch and even soil. A power rake takes the burden out of pulling this material out yourself, whether it be with a hand lawn rake or thatching tool. A hand pushed electric power rake / thatcher can be of great use. These tools look much like a lawnmower except that they have bristles or tines instead of blades.
The cylinder of tines spins around rapidly once the button is pressed, making shallow cuts into the ground as it is pushed along. The onboard electric motors never need gasoline or laborious care. Most have padded handles and can fold up between uses.
One of the more common ways to power rake a lawn is to install a special tool onto your rotary lawn mower. Consisting of a piece of metal that looks much like a lawnmower blade, these devices have a set of metal or nylon tines which spin around. When the mower passes over the ground, the rake removes ground-in debris so that it can be blown or hand raked easily. The device temporarily replaces the blade on the mower. You will need a box-end and socket wrench to perform the switch.
Large lawns are better power raked with a towable unit. Large power rakes attach to any garden tractor with a hitch. Users pull the rake across the ground to perform dethatching. Full or partially pneumatic tires run across the ground smoothly while the tines dig into the lawn. These tines are replaceable, as they tend to wear out over time. These large power rakes are best suited for people with a substantial amount of grass to cover. In fact they are rarely seen outside of commercial applications. Nonetheless, their sturdy powder coated metal casing and excellent coverage can make them a valuable asset to any homeowner’s tool collection.
Why do we do power raking and thatching in our yard? As the seasons change, grass dies and collects on the ground. It can form thick layers which do not allow oxygen and nutrients to pass through. Highly trafficked areas are prone to having compacted ground from all the shoes pressing it down. This not only hinders grass growth but creates a haven for bugs and pests.
