Modified Mower Hacks the Heavy Stuff

Clearing brush is no fun. Sure, swinging a machete on a hot, humid day sounds great, but when you’re sitting in an oatmeal bath the next day because you didn’t see the poison ivy, you’ll be looking for a better way. [RoboMonkey] did just that with a field-expedient brush trimmer that’s sure to help with his chores.

This is a hack in the true Junkyard Wars sense of the word. A cast-off electric push mower deck caught [RoboMonkey]’s eye, and a few spare brackets and bolts later his electric hedge trimmer was attached across the front of the mower. With a long extension cord trailing behind, he was able to complete in 10 minutes what would normally take him an hour to accomplish, without spending a dime on either a specialized brush cutter or a landscaping service. The video after the break reveals that it may not be the most powerful tool in the shed, and it won’t likely stand up to daily use, but for this twice a year chore, it’s more than sufficient. And since the hedge trimmer wasn’t modified, it’s still available for its original purpose. Reduce, reuse, recycle – and repurpose.

While we haven’t seen many brush cutters before, we seen plenty of mower mods. From LiPo electrics to a gas-powered RC unit, the common push-mower seems to be a great platform for all kinds of hacking.

[Lou’s] haircut really sucks

Ah yes, at some point a brilliant inventor combined the electric trimmer with a vacuum cleaner and the art of cutting hair was never the same again. [Lou] is showing us how to give a haircut that really sucks up the waste. And he did it using rubbish he had lying around.

Most people will recognize this as a DIY version of the Flowbee. Not surprisingly, you can still buy one of those if you want, but [Lou] is looking for a vacuum cutter for trimming his dog’s hair so he’s not about to shell out cash for it. He already has the trimmer, and just needed a way to attach the vacuum hose to it. In the image above you can see the grey crevice attachment for his vacuum. He taped it onto the trimmers, then cut a plastic soda bottle to use as a hood near the business end of the trimmer. It’s all wrapped in packing tape to hold everything in place and seal around the joints. You can see it in action in the clip after the break.

How to convert an internal combustion engine to run from steam power

We had no idea that what’s needed to convert an internal combustion engine to steam power is actually rather trivial. [David Nash] shows us how it’s done by performing the alterations on the engine of a string trimmer. These are the tools used to cut down vegetation around obstacles in your yard. The source of the engine doesn’t really matter as long as it’s a 2-cycle motor.

This engine had one spark plug which is threaded into the top of the block. [David] removed this and attached his replacement hardware. For now he’s using compressed air for development, but will connected the final version to a boiler.

There are only a couple of important parts between the engine and the boiler. There’s an in-line oil reservoir to help combat the corrosive nature of the steam. There is also a check valve. In the video after the break [David] shows the hunk of a ball-point pen that he uses to actuate the check valve. It’s really just a spacer that the piston pushes up to open the valve. This will be replaced with a metal rod in the final version.
