I need someone to explain this to me.

Remote Controlled Lawn Mower Lets you Sit Back and Enjoy The Show

Lawn Mower

“Its hard to find people that actually WANT to mow their lawn.” A more true statement has never been made. [Kurt's] project turns an old lawn mower into a remote control lawn mower.

The first step of this build is to replace the front drive wheels with mini-bike tires which have built-in gear tooth sprockets. The rear wheels were then replaced with large caster wheels. The 12-24V DC motors and gear boxes used come from National Power Chair. While we have seen more complicated RC lawn mowers before, this project is a great way to get started. All that [Kurt] wanted was to make lawn mowing more fun, we believe that he has succeeded. This thing is very mobile and can turn on a dime. Check out the demo video after the break.

What’s next? Add a GPS, a Raspberry Pi, and a few other odds and ends. Tie it together with some clever programming and you will have your own autonomous lawn mower. Have you already created a completely autonomous lawn mower? Let us know!

Electrified Yard Equipment Hauls Grass

mower2

[AmpEater] spent the summer converting yard equipment from internal combustion to electric power. The conversions run from a relatively tame Wheel Horse, to an insane Cub Cadet. The Wheel Horse lost its Kohler engine in favor of a hydraulic pump motor from a crown forklift. 48 volt power is supplied by MK lead acid gel cells. An Alltrax 300 amp controller keeps this horse reigned in.

On his Reddit thread, [AmpEater] says he is especially proud of his Cub Cadet zero turn ride on mower. For those who aren’t up on lawn implement terminology, a “zero turn” means a mower with zero turning radius. Zero turn mowers use two large wheels and tank style steering to turn within their own radius. We bet this style mower would also make a pretty good robot conversion, however [AmpEater’s] zero turn is still setup for cutting the grass.

After pulling the V-twin motor the 48 volt Motenergy ME-1004 was put in place. Batteries are 3 x Enerdel 48V 33 amp hour lithium ion packs. The packs are wired in series to provide 144V nominal. Right about here is where our brain started to melt. A 48V motor on 144V has to mean magic smoke, right? This is where the motor controller magic comes in.

Lawnbot400 saves wheelbarrow trips

We may be good at soldering but when it comes to hauling topsoil our scrawny arms quiver. [Johndavid400] did the smart thing here by letting the machine do all the work. Instead of hauling an entire truckload of dirt across the yard one wheelbarrow at a time, he built a shelf on the top of his Lawnbot400. We saw this lawnmower Arduino-powered, remote control mower back in November. The addition of its ability to handle some of the manual labor makes it the perfect backyard hack.
