How does this steer?

What kind of mechanism is this guy using to turn this track?

I saw this for sale on an episode of SOLD in TV and with a few close up
I saw the torque converter but curious if anyone can chime in
on how this puppy steers.


I'm tempted to orders his plans of eaby for $20 just to find out how
it works.
At 2:21 in th video you can freeze( stop) the video and get a better view. Looks like a disc brake on each side.But I only see one brake lever .
so turning the steering applies brake perhaps?

kind a cool

He is steering with a brake on each side. The little differentail he is using comes from
Northern hydraulics chain driven to the center open style. About 100.00 from Northern for a go cart. It works on something light like this.

is this the unit?

not seeing how this would allow slip between the two axles

what am I missing? .. The whole unit spins on a geared chain so

what allows for the differential on each side to slip... I'm assuming there are

spider gears just like a reg third member?

That is the one, it does have spider gears you are just locking up one side allowing the other to keep going you can do this with a normal open differential also from a rear wheel drive car or truck
