Homemade Electric Weed Whacker!

Electric weed whacker - diy

The following spare materials I had lying around to make a DIY weed whacker.

1. 18VDC electric motor.

2. Broom handle.

3. Pushbutton Switch.

4. LiFePO4 Battery 12.8V.

5. Microwave oven food cover.

6. PVC Trunking Cover.

7. 1.3mmsq 2 core copper wire cable.

8. XT60 connectors.

9. Miscellaneous Screws, bolts, etc.

The finished product actually impressed me with how well it cut those hard stem weeds.

Motor, Safety Guard and Cutting Blade.

The motor has 2 threaded holes for screws which I used to mount the clear plastic guard over. An 8inch length of PVC trunking cover I used as the cutting blade.

Power Supply.

This small 12.8V LiFePO4 battery is used to provide power via XT60 connectors and a pushbutton switch. The runtime is approximately 45mins.

Completion!

Homemade electric weed whacker.

With the broom handle attached with the switch and battery mounted, a short test confirmed proper clockwise rotation from the user's POV.

This whacker will be my new tool for yard maintenance since a new electric whacker is beyond my budget at this point. Also I hate those gas engine versions.
