Crop intake device for an agricultural harvester

A crop intake device for an agricultural harvester, the crop intake device comprising:

• (a) a frame;
• and
• (b) a crop pickup unit pivotably mounted to the frame, the crop pickup unit comprising:
• (i) a rotatable reel with a plurality of tines configured for picking up crop from a field;
• (ii) at least one support member for supporting the crop pickup unit on the field during use, the support member being pivotable relative to the reel for setting a minimum height of the tines by moving the reel between a lowered configuration and a raised configuration;
• (iii) a first suspension spring, coupled between the frame and the crop pickup unit such that a perpendicular distance between the first suspension spring and a pivot point of the crop pickup unit on the frame increases when moving the reel towards the raised configuration;
• and
• (iv) a second suspension spring, coupled between the frame and the crop pickup unit, such that a lifting torque provided by the second suspension spring on the crop pickup unit increases when moving the reel towards the raised configuration.
