The simplest way to build a branch shredder involves using an electric or gasoline engine. Here’s an example of how you can make your own branch shredder:
Materials Needed
- Engine
- Shaft – cutter (e.g., rotary)
- Frame (made from steel pipe)
- Knives on the shaft for cutting branches
Creating the Design
Create a blueprint on metal as shown in the image below:
The thickness of the casing is set with a metal strip – in this design, a 60mm wide strip was used.
Main Component: The Blade Disk
The main part is the blade disk, 30cm in diameter and at least 16mm thick. This disk serves as the base for attaching blades and also functions as a flywheel.
It’s advisable to order this part from a machinist who can cut a circle from a 1.5-2 cm thick metal sheet.
Blade Installation
For the blades, drill threaded holes in the disk for mounting.
On the opposite side of the blades, attach bars to the flywheel that eject the chips during the disk’s rotation.
Casing and Frame Construction
The casing is made from 12mm thick metal, though a thicker metal can be used for increased reliability.
The frame is made from 50x50mm angle iron, at least 5mm thick.
Ensure the entire structure is thoroughly welded.
Finishing Touches
In the center of the cover, drill a hole for the shaft as shown in the image.
Drill holes in the lower plate-wall for mounting on the wall of the support bearing.
Remember, the flywheel undergoes significant load during operation, so it must be robustly constructed.
After installing the belt drive on the flywheel shaft, your DIY branch shredder is ready for use.

Note: When using the branch shredder, always ensure safety. Wear protective glasses and gloves, and avoid placing hands or other body parts near the cutter.
Understanding Garden Shredders
Garden shredders are devices used for grinding garden waste such as branches, leaves, and other plant debris. They usually operate on electric or gasoline engines and can have various design features depending on the manufacturer and model.
Components of a Garden Shredder
The body of a garden shredder is its outer shell, protecting internal components and preventing debris from flying out during operation.
-
- Engine: This is the power source that drives the cutting element. It can be gasoline or electric.
- Cutting Element: This is the device that breaks down branches and other plant waste into smaller pieces. It is typically a rotor or knife disk rotating at high speed.
Description of the Garden Shredder’s Components
Here’s a general description of a garden shredder’s device:
- Body: The external shell of the shredder, protecting internal components and preventing debris from flying out during operation.
- Engine: The power source that drives the cutting element. The engine can be powered by gasoline or electricity.
- Cutting Element: The device that breaks down branches and other plant waste into smaller pieces. Usually, it’s a rotor or knife disc spinning at high speed.
- Funnel: The opening through which branches and other waste enter the shredder. The funnel is made of metal.
- Paddles: Devices that guide branches and other waste into the shredder and help prevent clogging.
- Speed Regulator: A device that allows control of the shredder’s speed and direction. Control can be manual or automatic, depending on the model.
A garden shredder is a useful tool for processing garden waste, quickly and easily turning it into mulch or compost that can be used as fertilizer for the garden.
