A lubrication system for a cotton harvester having a plurality of harvesting units. The lubrication system comprises a lubricant source for providing pressurized lubricant to each of the harvesting units to facilitate their operation and a control mechanism for measuring cyclic operations of harvesting units operating components during a harvesting procedure. The control mechanism controls operation of the lubricant source such that the amounts of lubricant provided to the harvesting units during a lubrication cycle is correlated to the lubricant usage of the harvesting units during the harvesting procedure. A salient feature of the present invention relates to a display for visually indicating the cyclic operations remaining for the harvesting units before another lubrication cycle is due to be commenced. The display furthermore provides a visual indication relating to the operating performance of the lubrication system.

Lubrication system for a cotton harvester

A system for monitoring cotton flow through a conveying system of a cotton harvester. The monitoring system includes acoustic sensors for generating pulses or signals as a function of sound produced from cotton impinging upon a walled conveying duct of the conveying system. The sensors are connected to detector circuitry which provides a first signal condition when cotton flow through the duct is above a first level and a second signal condition when cotton flow is below the first level. The system of the present invention further includes an alarm which is responsive to outputs from the detector circuitry.

An anti-theft security system for an off-road vehicle is disclosed. The system includes a master control module, which may be part of the vehicle's instrument cluster, and a remotely located security module, which is directly adjacent to at least one electrically-operated actuator of the vehicle normally operated as part of transporting the vehicle to another location. The security module includes a tamper-resistant housing which obstructs physical access to at least part of the actuator. The master module, which may include a microprocessor and LED display, has an operator interface such as a keypad for entering a first access code known only to authorized operators of the vehicle. When the sequence of entered keystrokes matches the first access code stored within the master module, the module automatically generates and transmits to the security module a signal containing a second and different access code. When the security module determines that the received signal is coded with the same second access code stored within its memory, a power switch within the security module is energized, thereby providing electrical power to the actuator so that the vehicle may be moved. The second access code contained in the signal transmitted between modules may be an analog signal encoded by using a special voltage, frequency or waveform, or a serial digital signal encoded with a multi-bit code. To further improve security, the master module is arranged to allow the first access code stored therein to be reprogrammed when a special sequence of keystrokes is entered.
