“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!

[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.

We’ve always felt that the hacker community is a unique one. Make reader [Gnomic] is reinforcing that feeling by running his own contest with unused equipment. [Gnomic] is offering a free Robot lawnmower to someone, as long as they send the completed project writeup to Make. The mower is a Robomower RL 850 and you have to pick it up in Richmond Va. To enter, you have to email [Gnomic] your proposal within the next 10 days. He will then choose what he feels would be the most interesting one to give the mower to. We’d love to see one of our readers get in on the action with this one. We would really love to see our logo on the final robot when it gets published to Make.
[Grayson Sigler] rolled out a new version of his robotic mower which he calls TOBY. The previous design added motors to a reel mower but he had trouble with traction. The new design is more of a utility robot platform that is used to tow the reel motor behind it. With better wheels, a much more stable base, and plenty of power this is a significant improvement.
His parts order came since we last checked in and he now has RC fully implemented. Check out the video after the break.

Challenged by hot days and steep turf [Grayson Sigler] modified his reel mower to use electric motors. The end product will be radio controlled but he lacked the necessary parts to make it wireless right now. Not to be deterred, he used a wired controller for prototyping and testing that should be easily replaced once the parts arrive. Sadly, the grade of his yard causes the small wheels to slip so he tried inserting screws into the tread for added traction. The small mower lacks the weight and footprint that the Lawnbot400 enjoys. That being said, solar charging is one of the future goals so this build, which he named RoMOW, wins out on the green scale. We’ve included the prototype video after the break that shows the blades spinning away.

[Kirov], a regular reader and one of our most notorious commenters, tipped us off about this lawn mowing hack. On one hand we’re wary that this is bait for a huge flame war, but on the other hand it’s a hack that brings a smile to our mischievous faces. By pounding a stake into the center of the yard and connecting a mower to it with a piece of rope, [Korey99] has achieve an automated lawn mower. He tied the self-propelled mower’s throttle bar down to make the machine run unattended. There’s no kill switch or any kind of remote control for the lawn mower so we wonder what happens when the rope gets all wound up?
Driven by the relentless nagging encouragement of the Hackaday commenters, [Johndavid400] has improved the Lawnbot 400. No longer does it just sport a makeshift wooden shelf. he now has a wheel barrow attachment. It looks quite sturdy as long as that front hinge holds out. There is an actuator coming in the near future for dumping the contents as well. Also, we suspect that might be a shovel in this picture.
