DIY "good at everything" small hybrid tractor for the yard

[VeNoM387]

Hello,

I've needed a machine like this for a while now for my 4500 sq meteres yard (1.1 acre) so I started building it
It is a "good at everything" DIY small hybrid tractor for the yard. Traction is 4x4, the motors are electric. The attachments are powered by a 7HP gasoline engine that also rotates a 24V 100A alternator that charges the batteries and supplies the energy for the two motors.
The first attachment I've done and has 2 x 41 cm blades, the one in the picture, is for cutting grass/weeds. It works GREAT.
Next comes a vacuum cleaner, a rotary brush, and possibly a snow blower.

To give you an idea of the size, the wheels are of a motor cultivator and have a diameter of 40 cm.
It is currently controlled with a FrSky Taranis controller, but the ultimate goal is to be autonomous.

Wow, interesting project for sure.

What's the weight? I think I'd prefer a wider tire for when the ground is a bit soft.

 

[VeNoM387]

The weight is over 120 KG. The wheels are 10 cm wide.
I used only 2/3 mm thick steel sheet cut on CNC plasma.
The frame is made of 40x40x2 mm square pipe.

One of our customers builds something similar. BURRO

thats pretty cool

Burro is really cool.

I just orderd a Raspberry Pi 4 8GB and Coral USB accelerator. I will use object detection and GPS to make my tractor autonomous.

I applaud your efforts, I don't have the smarts or the patience to tackle something like this, but what you've done is way cool.

I have the material (videos/photos) to do a full how to. I hope to do it soon.

Quick look : The 2nd test run:

That's very cool.
I assume your range is such that your don't have to follow it around. Can you also use it quietly on battery power alone for other uses?

 

[VeNoM387]

FrSky Taranis has quite a range, I tested it for a few KM with a rc paraglider.
I have to folow it to be precise near fences.
With the current batteries I can use it for 10 - 20 min on battery alone.
The next attachment.
Is a vaccum cleaner with 2 impellers.

Are you sure your not making props for a horror movie?
