Homemade Snowblower Tractor Drive System

The Drive System

My first snowblower donor had a chain driven reduction drive and the wiper was on the back which was problematic. It also had a shorter drive shaft and I wanted the tracking width to be as wide as possible.
5hp MTD snowblower drive system won't work for my needs.


Becuase of this I picked up a larger snowblower with a 10.5 hp engine. The wheels, driveshaft and drive system were larger. Perfect!

The drive selector was still on the rear, which makes sense for a snowblower, but not for the tractor. More on how I fixed that next.
This 10.5 hp snowblower drive system is just what I was looking for.

Homemade Tractor Made From Snowblower Parts

Our Homemade Tractor Made from a Snowblower Project


I've always wanted a small garden tractor and there aren't many to be found around my town, so I thought I'd see if I could piece one together using a common and easy to find cousin, the snowblower.

Each spring there are multiple people looking to clean up their yard of their old snowblower that "ran when put away last winter" so I snagged one for free and started looking at what I had to work with.

Separating the blower from the engine/drive and handles/controls


Snowblowers are pretty simple. The engine has a double v-belt drive pulley. One v-belt drives the wheels by spinning a friction plate and when the operator squeezes the drive handle, the friction plate swings into a waiting rubber rimmed friction wheel. This disk then turns a few gears or chain sprockets to drive the wheels. The gearing or speed of the drive system is controlled by a separate lever that moves a wiper, sliding the rubber friction wheel left or right on the shaft. As the rubber wheel crosses the center-line of the friction disk, it changes from forward to reverse.
            The second belt drives the snowblower when the handle is squeezed.
