FORE AND AFT MOVEMENT OF A PICKUP REEL OF A CROP HARVESTING HEADER

摘要

A crop harvesting header includes a reel mounted on a pair of forwardly extending arms carried on a header frame above a table and cutting knife. The reel is rotatable about a longitudinal axis and includes bats with finge rs which pivot each about a respective bat axis so the angle of the fingers varies as the reel rotates. The angle of the fingers can be varied to increase and decrease the angle at the knife. The arms include a forward portion which is arranged at an ang le to a main portion so as to be inclined downwardly and forwardly therefrom. As the reel supports on the arms is moved forwardly along the arms and engages onto the forward portion, the reel is moved downwardly and forwardly which simultaneously changes the angle to provide a more aggressive action as the reel is moved forwardly of the knife.
