From YouTube: MictroTractor Design in Process

Description

Tractors are a multi-billion dollar industry. Open source tractors mean that 1000s of small enterprises producing tractors can be created worldwide. Join the OSE development team to create universal access to tractor design and construction. http://opensourceecology.org/wiki/OSE_Developers

What you see here at Open Source Ecology is an ambitious program based on a volunteer effort. To help us reach the goals - please consider joining as an OSE Developer in 2017-

People, what do you think of us? This is looking just beautiful. It's a 20 by 20 by 30 power, cube very tiny such that the overall width of this tractor here is about 42 inches. This is a very tiny somewhat of an equivalent of a taro dango. If you look at do a little quick measurement here, 43 inches yeah, we want to get it down to about 42 or so that's the industry standard from the Toro dingo yeah and get rid of that distance there. But this is looking like a really nice and functional tractor.

A

We're gonna add the loader arms here. These are the place holders, but this is the same style that we did last year, except the the form factor is much much lower, meaning a practical machine before it was very tall, unworkable, dangerous. So here we're gonna, still add the probably mount the cylinders right in front here. Here's the loader arm so we're gonna have a loader plus a Quick Connect plate.

A

That's got a second cylinder and right now this is just 18 horsepower or 16 horsepower, depending on what kind of engineers, but the engine we use is a simple Duramax 16 horsepower for $229 pull-start, which is good, starts up every time we've tested it works really well and that's the power cube version. 17 point: oh eight, that we're showing here you can add new motors to this.

A

By just adding one of these engines, you can add an engine pretty much readily with a hydraulic pump, as shown here, the idea being that this one hydraulic reservoir here can fuel or power multiple engine pressure, pump engine, hydraulic pump, combinations, so just adding a simple engine without without having to add another tank or another cooler, because we can actually, if we oversize this cooler a little bit, we can run both through the same cooler for cooling.

A

Here's the hydraulic motor you see, the motor mounting plates have to be adjusted a little bit there, but that's one of the motors on one of the sides. We still need to add a tensioner here, a tract tensioner and we're probably gonna do that by putting up another idler slinging it from underneath. So we can actually punch up the track if the track is really loose. Kind of like dribbles down just kind of hangs down, we're gonna push it up with an idler. That's gonna spin span through here.

A

It's gonna, be a shaft going through the underside here or through this beam here, and we're gonna be able to rotate another idler into place, we'll kind of rotate up and lift the track up to tension it so that we can connect the track while it's loose, pretty readily challenges here, don't see much I think this is. This is pretty good. The challenge is gonna, be. Maybe how do you exactly mount the loader arm cylinders, but otherwise this is looking pretty good.
