摘要： A mower clipping collection system for a riding mower comprises a collector housing having an interior collection chamber and having an interior cylindrical wall forming a cylindrical separation chamber positioned above and in communication with the collection chamber. A clipping transfer conduit extends from the mower deck and is mounted tangentially with respect to the cylindrical wall of the collector housing such that mower clippings, entrained in a stream of air exiting the mower, are blown tangentially into the separation chamber through an opening in the cylindrical wall. The collector housing includes a floor which slopes downward to a clipping dump opening extending across a rear side of the housing. A door is pivotally mounted to the collector housing across the clipping dump opening and moveable in and out of covering relationship therewith by a door operating assembly engageable by an operator while seated on the mower. A blower, that is selectively engageable by the operator while seated on the mower, is connected to the clipping transfer conduit to facilitate the transfer of clippings. An exhaust duct is connected to the collector housing and extends from an exhaust opening therein to a downwardly directed exhaust duct outlet near ground level.

摘要： The present invention provides variable force traction enhance systems for vehicles. The systems include one or more hydraulic cylinders connected to an implement and fluidly connected to one or more hydrostatic transmissions. The hydraulic cylinders actuate the implement in response to changes in the hydraulic fluid pressures in the hydrostatic transmissions. The actuated implement automatically shifts weight to vehicle drive wheels to improve traction and automatically prevents a rear end of the vehicle from bucking.

摘要： A computer controlled grain dryer system includes a grain drying chamber, an air heater unit, and an arrangement of grain loading and unloading conveyors. A grain moisture sampling system receives a grain sample from the grain chamber and conveys the sample to a capacitive sample cell. A grain moisture meter measures grain moisture content as a function of the dielectric constant of the sample in the cell. A digital computer is interfaced with the moisture meter and the grain conveyor and is programmed to automatically control the grain sampling and the drying process. In continuous crossflow and concurrent flow dryers, the drying process is controlled by controlling the speed of grain flow. In batch type dryers, the process is controlled by way of the time that the grain is present in the drying chamber.

摘要： A computer controlled grain dryer system includes a grain drying bin, a solenoid valved burner, a blower, and an arrangement of grain unloading augers. An air temperature sensor for the drying airflow provides a temperature signal. A grain moisture sampling system receives a grain sample from the grain unloaders and conveys the sample to a capacitive sample cell. A grain moisture meter senses grain moisture content as a function of the dielectric constant of the sample in the cell. A digital computer is interfaced with the temperature sensors, the moisture meter, the burner valves, the blower, and the auger motors and is programmed to automatically control the grain sampling and the drying process according to a set temperature limit and moisture content for the particular grain to be processed.
