Open the CIPO recordAbstract From the Canadian patent
An implement lift mechanism for a grounds care device uses a lost motion interconnection between a rotary lift flange and an integral lift/connector link coaxial therewith to selectively control the height of the implement. The lost motion interconnection allows the implement to float upwards over uneven terrain. Additionally, a spring (or other means to apply force) can be used to assist in aiding the implement and reducing lift force.

Why it's free to use
- Filed June 13, 1997. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended June 13, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 13, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
