Good morning,

I had a thread a few days ago asking about a snowmobile engine on a hydro. With the vast knowledge on this site it sounds like that is a terrible idea. So here is what I am thinking instead.

I want to take the snowmobile engine and torque converter system and have it drive a live axle.

This would be a completely custom build from the frame, axle, body panels, ext..,

So here are the questions

1- would a 1inch live axle with keyed wheels hold up to pulling?

2- what sprocket ratio would I need to put the most torque to the rear axle?

3- Would this even work for a pulling application?


I hope what I am wanting to do makes sense, it's a little hard to describe in word. I will get pictures up of the components tonight.

1. Probably, though 1 1/8 would be better.

 

2. One of the Cub guys would have to figure what the total reduction is through their drive train.....   and if you want to change the ratio, what then???

 

3. Maybe. I thought you wanted to plow snow, too?

 

Anything is possible. One guy who pulls in this area has a Suzuki Hayabusa engine.

I did want to snow plow but you know how things change. I suppose the old 180 JD will have to keep doing that job since the cub rear end is not much use with this engine. (FYI I have a hydro cub rear end for sale cheap)

 

I was searching online the other day and found a chart that gave me the gear ratio on 4wheeler sprockets (basically the type of drive I am thinking) and If I put a 11 tooth gear in the front and da 72 in the rear it make it basically 4.10 gears. Now I know that is pretty good for pulling trailers with a truck but I didn't know if that would be low enough for tractor pulling.

Exactly what I am thinking. Is that yours or just a video on youtube?

Here are a few pictures of what I am starting with.

 

The whole snowmobile

I am going to custom build a frame from some scrap channel iron from a hay wagon we rebuilt at school. I am on a search for a hood from an older tractor or may just fab my own. Im thinking I will use some trailer fenders over the tires and an old tractor seat. 

 

So the next question is how long should the frame be 6-7ft?
