Lawn Dog is an electric / robotic solar charged lawn mower project that evolved from my first robot lawn mower. Lawn Dog however can reach into ditches which is awesome . The new setup allows for a variety of attachments. A solar panel charges batteries during the day but can be charged by normal 110v outlet if needed It takes 2-3 days to charge by solar, which is fine.
The main goal is to make a product that is both versatile and useful outdoors. Lawn work is not always easy and many people have trouble if they have physical impairments , advanced age or sensitivity to outdoor heat or sunlight. Lawn dog is a work horse that takes the difficulty out of property maintenance and is also good for the environment!
I have additional attachments in the works like...
Leaf and trash recovery ( made from a modified electric sweeper)
Spiked aeration turf roller
Fertilizer/ seed spender
22 inch rolling magnet picks up screws, nails and more after projects.
I used a box of 100 screws and drive them into the solid rubber tire, the screws seemed to work really well at holding grip. I may consider moving to a all rubber tractor tire , but this is working fine. The screw heads stick out .5 inches. I will clean them off and coat the tire and screws with a thick coat of liquid rubber from plastidip so I can keep them from scratching the driveway and also have matching black wheels / tires. This guy also needs a paint job !!
First time out in the yard with high grass, I immediately noticed that the wheels are too slippery to keep any grip. I will try some other options to get good grip on the soil without damaging the yard.
Ok so I picked up some hardware. 1/2" steel zinc threaded rod , nuts, wing nuts and lock nuts. Should be able to basically slide the shaft in or out by unscrewing a wing nut when done. I removed the original axle and it appears to fit in fine.
Next I need to pull out the grinder and cut away the center post that is in the way and drill out all the holes the shaft will slide through to 1/2"
started stripping down the jazzy and removing brackets , wires and controller that will not be used, it has a circuit breaker set for 30 amps , hmm I wonder if I will leave it in, 15 amps max per battery is not a very high ceiling.
