A louver position sensing system for a sieve and chaffer of a combine harvester. One system provides that at least one sensor is in actual, physical contact with one or more louvers of the sieve and chaffer. Another system provides that a one or more magnet holders are mounted on louvers and, spaced away, sensors sense magnets in the magnet holders to determine the rotational position of the louvers. Either system allows for accurate, on-the-fly adjustment of the louvers in order to maximize the efficiency of operation of the sieve and chaffer. Preferably, the sensing systems are configured such that sensed position of the louvers is broadcast on the CAN bus of the combine harvester. As a result, the position information can be used to dynamically adjust the openings between the louvers of the sieve and chaffer to achieve more efficient grain cleaning as the machine and field variables change.

An hydraulically operated vehicle lift having an electro-hydraulic power unit mounted on one of the lift columns for supplying fluid to the hydraulic actuator for raising the lift carriages. The electro-hydraulic power unit has an electrical junction box mounted on the motor and a manually operable switch and a lift limit control switch mounted on the junction box and electrically connected inside the box to each other and to the motor windings. The lift limit control switch is actuated by a flexible switch actuating line that has a portion extending crosswise between the lift columns at a level to be engaged by the roof of a vehicle being raised, to stop the power unit.
