Recently i started my metals 3 project/ small engines project, my small engines teacher gave me a snow blower. I had the idea of using the motor to power the go cart. Im salvaging the tracks off the snow blower to set up in the back instead of wheels. The front is gonna have two wheels that is held in place with pins so i can remove the wheels anytime its snowing and change them out for skis. i need input to try to refine my idea and i need an idea on how to steer the cart.
:huh:

on some airplanes they have skis and snow. that wheels stick threw the skis so they can go on dirt. as for steering use short skis

Also one of my problems is how am i gonna steer the tracks? because the tracks are gonna keep moving forward so some how i need to slow one side down to turn that way.

You need to set up dual brakes on the rear tracks just like on a tractor or tank, this would also help with the steering. Most tractors acutally have two pedals next to eachother to control the rear braking but that won't be as easy to set up on a kart. Maybe hand controls mounted on the steering wheel would be better or rig something up so that when you turn the steering wheel it pushes down on a lever that controls the brake on that side.

Just a few quick thoughts but nothing that I've done but might help get the brain gears turning for ya.

You don't NEED to do the independent braking. Live axle karts just don't steer as well but the tire (or track) on the inside of a turn will slip a bit allowing for the vehicle to steer. Letting off the gas also helps as the axle is only spun by forward momentum, not the motor. This will save you time and money as it's much easier to set up and get working. Shorter skis will work better as they are less cumbersome and will cut sharper than long skis. Check YouTube for "ski bike".

Also, Macfarlane, your steering is a tried and true system. It's basically tie rods, spindles, a pitman arm, and steering shaft. Even if you use his ideas, do NOT use threaded rod because, quite frankly, it's sh**. Also, do not bend then rod as this will be a weak point and will lose original shape over time.

Any tracked snowblower I have ever seen has reasonably small tracks. I don't think you need a skidsteer or indy brake setup. For the size of the contact patch, the snow will provide enough slip.

If you had twin snowmobile tracks, well that may be another matter...

We don't have much of a need for snow blowers in Texas so I guess I wasn't thinking about the size of the tracks. I was just going off of what I know and that's the tracks for snowmobiles so..............my bad. :)

I'm only 3 hours from Ruidoso New Mexico, It's ok place to play in the snow when they get it.

It will do fine as, I'm assuming, the treads aren't much longer than 15". Any loose surface will give better performance, much like a live axle kart, but will be OK on pavement.

actually ya kinda like that except the treads are half the distence from eachother and more of them
~also i live in alaska so we have a beach to drive it on plus it snows frequently
~also do you think a 7 hp snow blower motor should do the trick?

My kart has a live axle (2wd) with no differential so, even on a turn, the tires both spin the same number of times as they are locked together. I'm saying you don't need to have them brake independently because one side will slip a bit and allow the kart to turn. It won't turn as well, but it will handle fine.

iv got to say im **** sure your going to need atleast a differential in the rear and skis with a fin or two for turning. a live axle with tracks and skis is not going to turn at all
