Here is a closer view of the working harvester.
On the front is a complex, two metres wide mechanism. It has a revolving rake that lifts the crop, and presents it to the gang of scissors...the scissors cut the seeds heads off the plants along with some of the straw...the severed seed heads are then moved to the elevator by a large revolving drum screw...the elevator lifts the seed heads up to the thresher, which separates seeds from the seed heads and straw. The mechanism takes its power from the main diesel engine, and utilises it with the aid of a bewildering combination of chains, belts, rotating shafts and hydraulic rams.
A key role of the driver is to constantly tune the height of the rake and the scissors, at the same time as steering the machine and watching out for potentially disastrous tree stumps or other obstructions...all these adjustments are made with two joysticks. Na's brother and nephew have become quite adept at driving this machine.
On one side is a platform on which one or two people can operate the bagging mechanism...typically bags are made from hemp, have 4 bushell capacity, and weigh 100kg when filled.
