These are typically larger that the walk-behind machines and can have a clearing width up to 57 inches or more (nearly five feet).

They are usually fitted to the front of the tractor or lawn tractor, utilizing an available power take off (PTO), and basically work in the same way as the two stage machines referred to above.

Tractor mounted snow blowers, like those from John Deere are for large areas or for quick snow removal.

Two-stage snow blowers will handle most wet, heavy snowfalls with ease, as well as deeper snowfalls of up to twelve inches.  In addition, two-stage blowers are self-propelled, so you only need to guide them.  This doesn't necessarily mean they're easy to handle, as anyone who's ever been covered in a mountain of snow tossed by his own snow blower can attest!  Most two-stage blowers have at least two forward speeds and one reverse speed.  They also have a four-cycle engine, which is cleaner and doesn't require mixed fuel.  One disadvantage is that they do not provide as clear a path as a single-stage blower, since the auger never touches the ground.
