Embodiment Construction

[0027] The terms "side to side", "to one side", "laterally" or "lateral" refer to a direction that is horizontal and generally parallel to the longitudinal extent of the reciprocating cutter and the longitudinal extent of the agricultural harvesting head itself . This direction is perpendicular to the direction "V" of movement of the agricultural harvesting machine and agricultural harvesting head as it moves through a field to harvest crops. The terms "in front", "in front", "forward", "forward", etc. refer to the direction of movement "V". The terms "rear", "rear", "behind", "to the rear", etc. refer to a direction opposite to the direction of movement "V".

[0028] figure 1 Here, header height sensor device 100 includes a mounting bracket 102 , a sensor arm 104 and a sensing element 106 .

[0029] Mounting bracket 102 is configured for securing to an agricultural harvesting header 108 ( figure 2 ). The mounting bracket 102 is pivotally coupled to the sensor arm 104 to...

Abstract

A header height sensor arrangement (100) configured to be fixed to an agricultural harvesting head (108) comprises a four bar linkage comprising four bars (110, 112, 118, 124) and a sensing element (106), wherein the sensing element (106) is disposed to sense relative movement of at least one bar of the four bar linkage with respect to another bar of the four bar linkage.

Description

technical field [0001] The present invention relates to agricultural harvesting equipment. More specifically, the present invention relates to sensors for detecting the height of agricultural harvesting headers. Background technique [0002] Agricultural harvesting machines, such as windrowers or combines, typically have an agricultural harvesting head supported in front of the agricultural harvesting machine that carries the agricultural harvesting head to harvest crops in a field. [0003] These agricultural harvesting headers are typically dynamically adjustable in height relative to the self-propelled vehicle. This adjustment is typically made by an electronic control unit (ECU) monitoring a height sensor that indicates the height of the agricultural harvesting head above the field. [0004] The ECU reads the height sensor, determines if the agricultural harvesting head is too low or too high, and if the agricultural harvesting head is too high or too low relative to t...
