A rotary platform is provided for the harvest of specialty crops such as grass seed. In particular the conditioning rolls are removed from the header to reduce seed shatter and converging elements are added inside the conditioner opening on both sides and to the rear of the cutterbar to feed the crop around the conditioner opening corner and to the rear of the platform. Additional converging elements are provided behind the first converging elements at a angle less then 90 DEG. to the ground so as to form the top of the windrow so that there is minimal seed loss. The converging elements may or may not be powered and the angle of the second converging element can be adjustable. The rotary knives perform the cutting function more efficiently than a sickle cutterbar, and the converging elements move the crop toward the center to form a windrow with less disturbance.

A load control system, in certain aspects, may be configured to decrease the amount of noise pollution of a prime mover (e.g., engine) of a service pack in that it may not require the prime mover to operate at higher discrete operating speeds to deliver small amounts of air from the air compressor. The load control system may also only increase the speed of the prime mover to a minimum discrete speed required, keeping noise at a minimum. The load control system may also maximize fuel efficiency by not operating the prime mover at the highest discrete speed at all times. More specifically, the lower operating speeds may lead to less fuel consumption.

Method to operate a combustion device in a house or similar building, with fossil fuel furnaces, such as wood or oil furnaces. Outdoor air is supplied to a heat exchanger that is connected to the smoke tube of the furnace, in such an amount that an interior excess pressure is created, as excess air is led out of the interior of the building through one or more exhaust openings, especially exhaust devices, which are located at low places in the building at its outer side. This offers better combustion efficiency, better energy-utilization and a more uniform temperature in the building. A device for operating the method, comprises a fan (23) which takes in air from an inlet (19) near the outer walls of the building, through a tube (24) leading to the furnace, with a heat exchanger (33, 34) enclosing some of the smoke tube (18) of the furnace (17). The fan (23) is dimensioned and operated to create an overpressure in the building. There exists at least one overflow valve (25) placed in the lower parts of the building, near its outer wall, which opens upon a low inner pressure.
