Abstract
The present disclosed invention relates to a quick switching mechanism for the side discharge unit and the chopper unit of a lawn mower: a side discharge unit and a chopper unit are mounted at the grass outlet on a cutting platform; wherein, the side discharge unit comprises a grass discharging gear shaft, a grass discharging hood mounted on the grass discharging gear shaft; the grass chopper unit comprises a grass chopping gear shaft, a grass chopping closing plate mounted on the grass chopping gear shaft; the small gear on the grass discharging gear shaft is engaged to the big gear on the grass chopping gear shaft; a guy wire is mounted on the cutting platform, and is connected to a rotary arm mounted on one end of the grass chopping gear shaft. In the invention, the current grass discharging hood is kept, and therefore the safety of grass discharging is not compromised; during the mowing process, when the mower runs into a place (e.g., a kerb, shrub, etc.) where the grass discharging process is difficult, the mower can be switched from grass discharging mode to grass chopping mode immediately; after the mower passes the place, it can be switched back to grass discharging mode quickly; if the mower runs into a narrow place (e.g., the space between two trees), the mower can be switching from wide discharging mode to narrow discharging mode immediately; the mower can be switched back quickly after it passes through the place.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
