Abstract: An operator presence system for a cotton harvester including an on-board cotton module builder, the system including a mount for installing a ground access ladder at a first position for providing access to a service platform for routine service and maintenance, and a second mount at a second location for installing the ground access ladder adjacent to a ladder segment extending to an upper region of the machine, the mount at the second location including a switch or other device for disabling or locking out at least a hydraulic system of the module builder when the ladder is mounted to the second mount, and which re-enables operation when the ladder is removed therefrom.

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: An air inlet and service access arrangement for the cab of a work vehicle. A plenum, having a filter mounted therein, is secured to the inside of a louvered door, such that outside air may be drawn through the louvers and the filter, to be supplied to the cab air handling system. By opening the louvered door, the filter may be removed for servicing or replacement, and access is provided to serviceable components of the air handling system and other work vehicle systems located behind the door.
