This is something every homeowner needs! A Kit that easily converts a 21inch Lawnmower into a robot that can be driven with remote control or for the adventurous made to cut the lawn autonomously.
We have built many remote control lawnmowers over the years and keep getting requests for a DIY kit. This kit will allow you to take a standard 21-inch lawnmower and modify it to mount to this chassis. By default, the lawnmower is not included but if you wish you can select for us to include it in the options below. We can modify this kit to work with other lawnmower decks if needed but the mower we are using is Huskee 21" mower. If you need something customized
contact us for a custom robot quote.
The frame of this robot is made from tube steel and heavy gauge steel cut on our CNC plasma table. It is welded together in a jig we set up so the lawnmower inserts into the frame using the existing wheel mounts, which also lets you set the height of the deck.
The robot is driven by the provided 13-inch tires in the back driven by heavy-duty wheelchair motors. The 6-inch casters in the front allow easy maneuverability. This mower is faster, more powerful and has longer run time than our previous version.
The robot weighs about 180lbs with motors, batteries, and lawnmower.
