摘要:
In a sickle cutting system, it has been found that a significant reduction in average stubble length, which is calculated based on the distance crop is pushed forwardly without cutting occurring, can be obtained by a combination of features where the length of the cutting edge of each knife blade is increased to a length greater than 2.2 inches; the width at the rear of the ledger surface of each guard is increased to greater than 1.2 inches; and the front edge of the blade is formed with an apex to shed crop material to one or other side of the apex. Each blade has at least one cut out opening through the blade extending from a rear edge of the opening adjacent to but spaced from a rear edge of the blade toward the tip.
