The mounting bracket has two U-shaped rods with downward extending legs adapted to be slid into the tubes to thereby quickly mount the blower to the cart by merely vertically lowering the blower onto the cart. The blower can be quickly dismounted from the cart by merely upwardly raising the blower from the cart with the rods merely sliding out of the tubes.

Why it's free to use
- Filed April 1, 1999 and granted June 12, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 1, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 1, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
