摘要： The present invention relates to a sliding pulley drive mechanism in cutting platform of lawn mower. An engine for the pulley drive mechanism is fixed to a chassis; a cutting platform is connected to the chassis, and can move up and down in relation to the chassis; a bracket is fixed to the cutting platform; cutting platform drive belts are fitted over the output shaft of the engine, an external spline shaft is fixed to the output shaft of the engine, and a belt pulley with an internal spline is mounted on an external spline shaft; the cutting platform drive belt is mounted on the belt pulley with an internal spline; the lower end of the belt pulley with an internal spline is connected with a shock absorbing bushing, a bearing, and a bearing base plate. The bearing base plate is connected to the bracket. In this invention, with a spline mechanism, the belt pulley on the engine can slide up or down on the output shaft of the engine as the elevation of the cutting platform is adjusted, so that the cutting platform drive belts are kept in the same plane, and therefore the belt service lifespan is elongated.

摘要： 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.
