Abstract: A rotary lawn mower includes an internal combustion engine, a blade, and a deck. The internal combustion engine includes an engine block having a crankcase and a cover. The crankcase surrounds a crankshaft, which powers the blade. The blade spins below the deck during operation of the rotary lawn mower. The deck is integrally formed with the cover.

Abstract: A method and apparatus for providing improved lubrication of a spline connection between a PTO driver and a bevel gearbox in which lubricant from the bevel gear housing is directed to a location above and radially outwardly from the splined connection and the apparatus then directs the lubricant flow toward the splined connection by force of gravity. The apparatus is configured to be self-aligning when installed in an existing receptacle in the gearbox housing thereby enabling the apparatus to be conveniently installed in a housing designed to utilize gearbox lubricant to lubricate the splines.

Abstract: An improved cotton harvester having a plurality of harvesting mechanisms, each harvesting mechanism having at least one light grease receiving area including a picker bar having a plurality of rotatably driven picker spindles, and at least one heavy grease receiving area including a cam and a roller arrangement and a gear arrangement for drivingly oscillating the picker bar, and an automatic lubrication system for periodically lubricating the light grease receiving area with a light grease at a first pressure, the improvement including a heavy grease reservoir on the harvester for receiving a quantity of a heavy grease; a pump on the harvester having an inlet connected to the heavy grease reservoir and a discharge, the pump being operable for drawing the heavy grease from the heavy grease reservoir and discharging the heavy grease from the discharge at a second pressure which is substantially greater than the first pressure, the discharge being connected to one end of at least one high pressure lubricant line

Abstract: The present invention provides a lubrication system and method for a work vehicle having a lubricant reservoir and a lubricant using attachment that comprises a single bi-directional pump/motor set, a single three-position/four way control valve that directs hydraulic fluid, through one of two flow limiting devices, to the hydraulic motor to power the pump. In one mode the pump, at a slow rate of approximately one gallon per minute, moves lubricant from the reservoir to the attachment. In the other mode the pump, at a fast rate of approximately six gallons per minute, moves lubricant from a lubricant source to fill the lubricant reservoir. The flow limiting devices can be either a fixed flow rate device or a multiple flow rate device as selected by an operator of the work vehicle. The various positions of the control valve can be actuated by a solenoid, a hydraulic cylinder, a pneumatic cylinder or a cable, all of which can be operated from the cab of the work vehicle.
