The cylinder on a Gleaner rotary is fed from the right side. In order to accomplish this, the feeder-house is narrower than seems likely to be able to feed a high capacity machine. The Gleaner overcomes this by running the feeder-chain much faster than other makes do. The crop mat delivered, is processed by the cylinder without need for turning, twisting, or folding that is necessary in other rotaries.

The integral pneumatic chaff spreader uses the massive blast of air that is delivered to the grain falling from the accelerator rolls to also distribute the chaff as it leaves the combine.

The area outlined in red is the chute that delivers the threshed straw to the straw spreader paddles.

A view of the cleaning area. The accelerator rolls are barely visible in this picture. They throw the grain downwards and slightly forward where it lands on a cushion of grain that stays on the grain pan. The air blast comes through the nylon fingers pictured. Because the grain is traveling 6 times faster than gravity would propell it, it is possible to blow high-velocity/volume air through it and not worry about blowing the heavier grain over the sieves. I maintain that there is no excuse for any chaff to ever touch the sieve of a properly adjusted Gleaner. The combination of excellent, gentle threshing and the un-surpassed cleaning accomplished by this system is the reason that grain buyers often have favorable comments on wheat harvested by a Gleaner.

The processor is accessable through a door in front of the engine. Gas assisted struts help the operator open the compartment with a minimum of lifting.

A view looking down on the distribution augers. All rotaries have a 'sweet spot' where most of the grain leaves the cylinder. If allowed to fall on the sieves directly, it will overload one part and leave another part un-used. Other makes often use cover plates to hold the grain in the thresher longer than necessary. The Gleaner allows it to leave the cage as soon as it can. It then uses the distribution augers and accellerator rolls to present a very even load to the whole width of the sieve. Yet another reason for the un-rivaled sample quality from a Gleaner.

A view of the cylinder inside the cage. The Cylinder in the R6x and R7x consists of 8 rows of cylinder bars around it's circumference. Each row of bars is composed of four bars and one discharge paddle bar that are bolted end to end to make up it's full length. The majority of the thresher/seperator bars are cast in a pattern that works in conjunction with the helical channels to move the mat smoothly through the length of the processor. Reverse bars are cast with a pattern that severely disrupts and tumbles the mat. The proper number and placement of these reverse bars is a subject of much discusion. Reverse bars take a lot of horsepower and it is now generally agreed that their use should be moderate, if at all.

The cylinder is very easy to remove on a Gleaner, so experimentation with numbers and placement is fairly painless.
